** Setup
First you need to install [[http://www.gnu.org/s/emacs][Emacs]]. Then you have 2 ways to install
[[https://github.com/ergoemacs/ergoemacs-mode][ergoemacs-mode]].
#+begin_o_blog_row 5
#+HTML: Using elpa
If you are using emacs 24 it should be very easy to install.
type:
#+HTML: Alt +x list-packages
#+HTML: After, find the package ergoemacs-mode
and install it with i x
Then add the following to your =~/.emacs= or =~/.emacs.d/init.el=
file:
#+begin_src emacs-lisp
(package-initialize)
(require 'ergoemacs-mode)
#+end_src
#+o_blog_row_column 6
#+HTML: Manual setup
Start by cloning the main branch /git/ repository from [[http://github.com][Github]]
#+begin_src bash
cd ~/.emacs.d
git clone -b master --single-branch https://github.com/ergoemacs/ergoemacs-mode.git
#+end_src
And add following to your =~/.emacs= or =~/.emacs.d/init.el= file:
#+begin_src emacs-lisp
(add-to-list 'load-path "~/.emacs.d/ergoemacs-mode")
(require 'ergoemacs-mode)
#+end_src
#+end_o_blog_row
** Enabling ergoemacs-mode
To enable emacs, add the following to your =~/.emacs= or =~/.emacs.d/init.el= file:
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-theme nil) ;; Uses Standard Ergoemacs keyboard theme
(setq ergoemacs-keyboard-layout "us") ;; Assumes QWERTY keyboard layout
(ergoemacs-mode 1)
#+END_SRC
For other key themes and keyboard layouts the initilization code
[[file:key-setup.html][should be different]]. However, for QWERTY, the key bindings are:

The current changelog is [[https://github.com/ergoemacs/ergoemacs-mode/commits/master][here]].
The historic changelog is below:
** Version 5.8.0.1 2013-07-5
There are many changes that were missed, but will be added to this
changelong in future releases. The biggest change for this release is
movind to o-blog to generate HTML and changing `variants' to `themes'.
I believe that theme is easier to understand.
** version 5.7.5, 2013-01-29
some minor fix to prevent byte compile errors.
** version 5.7.4, 2013-01-26 much more fixes and features by Matthew Fidler
to be documented later.
also, the commands “ergoemacs-forward-block” and
“ergoemacs-backward-block” improved. Now they skip empty lines with
whitespace in them properly.
** version 5.7.3, 2012-12-14 major rewrite by Matthew Fidler
A rewrite of the mode, with the following user-visible changes and
features:
*** Generate layout diagrams in SVG format
Call “ergoemacs-extras” to generate diagrams in SVG format for all
supported layouts.
The files are generated at the `user-emacs-directory' e.g.
〔~/.emacs.d/ergoemacs-extras/〕.
SVG files can be viewed in InkScape or modern browser (Firefox, Google
Chrome, IE9, …).
*** Generate AutoHotkey source code
for System-wide ErgoEmacs keybinding on Microsoft Windows.
Call “ergoemacs-extras” to generate AutoHotkey source code.
*** Generate Bash 〔.inputrc〕
for ErgoEmacs keybinding for unix terminal.
Call “ergoemacs-extras” to generate.
To install, follow the instructions in the generated file.
*** Generate Mac OS X 〔DefaultKeyBinding.dict〕
for system-wide ErgoEmacs keybinding or Mac.
Call “ergoemacs-extras” to generate.
To install, follow the instructions in the generated file.
*** Customizable by “customize-group”
You can customize keys by calling emacs's “customize-group” then give it “ergoemacs-mode”.
Here's some technical description:
- Added the customizable variable `ergoemacs-variable-layout' which
defines keys based on the QWERTY layout. You can customize this
variable to suit your needs. Also you can save your customization
so that You do not have to learn new keys every time a new ergoemacs
mode is introduced.
- Added the customizable variable `ergoemacs-fixed-layout' which
defines keys that are the same regardless of the layout. This
includes standard keys such as 【Ctrl+s】 for saving. For this
layout I added 【Ctrl+z】 for undo, 【Ctrl+Shift+z】 for redo,
【Ctrl+y】 for redo
- Added the customizable variable `ergoemacs-minor-mode-layout'. From
this variable all of the minor mode and major mode hooks are created
and setup. When using `minor-mode-overriding-map-alist' as the
keybinding to modify, an additional keybinding variable is created
per mode.
If you wish to freeze your keybindings, but keep current with the
ergoemacs trunk, you can save all of the customizable variables and
your layout will be saved between upgrades.
*** For developers: a better mechanism for key/command map
The internal working of the mode for mapping commands to keys has
completely changed.
Now, each layout are defined using visual diagram similar to
ASCII-art. This allows developers to easily add new layouts or change
keys.
See 〔_README.txt〕 file that describes the tech detail of how layout
format to be read by ErgoEmacs emacs lisp code.
** version 5.6.0, 2012-11-21
The command for cancel “keyboard-quit” is changed from QWERTY 【Alt+n】
to 【Esc】. Reason: I think it's overall slightly better, because: ①
it's more familiar. ② involves a single key. The disadvantage is that
on terminal, Meta can no longer be pressed by 【Esc】 (but can still
be done by 【Ctrl+[】). I think Esc for Meta is really bad, from the
1980s. I think it's rare to find a terminal app today that do not
support Alt as Meta.
** version 5.5.7, 2012-09-28
Added functions:
“cut-line-or-region”
“copy-line-or-region”
Replacing previous “defadvice” functions:
“kill-region-key”
“kill-ring-save-key”
because these “defadvice” functions causes emacs to spit this warning
“ad-Orig-kill-region called with 3 arguments, but accepts only 2”,
since about emacs 24. Haven't looked into why it's doing that.
** version 5.5.6, 2012-08-14
removed a bad code:
(eval-when-compile (log-edit-mode))
there's no function “log-edit-mode”.
** version 5.5.5, 2012-07-10
Added commands “unfill-paragraph”, “unfill-region”. These are useful
when doing keyboard macros. (in addition to “compact-uncompact-block”)
** version 5.5.4, 2012-07-10
Modified forward/backward bracket functions
(e.g. “backward-open-bracket”) so that they don't print a error when
reaching end.
** version 5.5.3, 2012-06-05
• Added a French layout support.
• Added 【Alt+6】 for “select-current-block”. Experimental.
• Added 【Alt+7】 for “select-current-line”. Experimental.
** version 5.5.2, 2012-05-25
• 【Alt+Shift+u】 was “beginning-of-defun”, is now “backward-block”
• 【Alt+Shift+o】 was “end-of-defun”, is now “forward-block”
Rational: after tried the beginning/end of defun, i didn't find it as usable in comparison to backward/forward block. Because, in many modes such as python, HTML, plain text (email, irc, text document), the defun one is useless. However, the move by block is applicable to vast majority of modes.
I think the navigation of defun and sexp has one nice key group. e.g. Ctrl+Alt+arrow move by sexp, and Ctrl+Alt+home/end does defun. So, that's a nice set there.
** version 5.5.1, 2012-05-25
*** Changed behavior of 【Alt+‹arrow keys›】
Before, 【Alt+‹left/right›】 move cursor backward/forward to left bracket positions, and, 【Alt+‹up/down›】 does the same to right bracket positions.
Now, 【Alt+←】 does “backward-open-bracket”, and 【Alt+→】 does “forward-closing-bracket”.
Now, 【Alt+↑】 and 【Alt+↓】 does backward/forward block.
A “block” is text between empty new lines. (similar to emacs's “paragraph”)
Rational: Several advantages with the new way.
① reduces the number of keys needed for navigating to all possible left/right bracket points. Before, it needs 4 keys, now 2.
② the new way is more intuitive with emacs. The forward key moves to end of things, and backward to beginning of things.
③ advantage of backward/forward block: GNU Emacs has {【Ctrl+↑】, 【Ctrl+↓】} for backward/forward paragraph. The problem is that “paragraph” is dependent on major mode's syntax table, so the behavior is unpredictable, and “paragraph” isn't well defined in computer language modes. e.g. in “html-mode”, it seems to move in funny way. The new behavior is predicable and useful. It's useful because vast majority of text uses empty lines to separate blocks of text.
** version 5.5.0, 2012-05-24
Major change.
• 【Alt+Shift+j】 was “beginning-of-buffer”, is now “backward-open-bracket”
• 【Alt+Shift+l】 was “end-of-buffer”, is now “forward-close-bracket”
• 【Alt+Shift+u】 was “backward-paragraph”, is now “beginning-of-defun”
• 【Alt+Shift+o】 was “forward-paragraph”, is now “end-of-defun”
Rational: the beginning/end of buffer command is not frequently used. Their replacement, the backward/forward bracket is much more useful in any programing language with brackets: (){}[].
Similarly, the movement by defun is probably more useful than movement by paragraph, because most emacs users are programers. The concept of “paragraph” isn't well defined in programing languages. But the defun movement also work with C-like syntax languages as well as lisp.
Thanks a lot to David Capello for suggestion and discussion. See: http://dacap.com.ar/programming/keyboard-layout/
〈Comandos de programación básicos de Emacs (forward-sexp, beginning-of-defun)〉 @ http://youtu.be/BuxJesmNc64
Also, implementation of {forward-open-bracket, backward-open-bracket, forward-close-bracket, backward-close-bracket} is reverted to not dependent on syntax table. Because, for example, in cperl mode, the curly bracket {} doesn't have bracket syntax.
** version 5.4.9, 2012-05-22
*** improved implementation of forward-open-bracket, backward-open-bracket, forward-close-bracket, backward-close-bracket
They now include the straight double quote char (Unicode U+22)
Part of the new implementation are now based on syntax table.
Not sure this is a improvement, because depending on syntax table makes the command unpredictable.
This is experimental change.
** version 5.4.8, 2012-05-20
*** added 【Alt+Del】 to delete word to the right.
** version 5.4.7, 2012-05-17
*** added 【F4】 for paste previous “yank-pop”
** version 5.4.6, 2012-05-15
*** added commands to traverse brackets.
“forward-open-bracket” 【Alt+→】
“backward-open-bracket” 【Alt+←】
“forward-close-bracket” 【Alt+↓】
“backward-close-bracket” 【Alt+↑】
Note: other minor modes may over-ride these keys. e.g. “org-mode”.
*** added “forward-block”, “backward-block”
These commands currently don't have a key. You may bind the keys for “forward-paragraph” and “backward-paragraph”. Call “describe-function” on “forward-block” for detail.
*** added commands to select line, block text, string
Added:
“select-current-line”
“select-current-block”
Modified
“select-text-in-quote”
to also work on single quotes. e.g. 'some thing'
** version 5.4.5, 2012-05-14
*** on Windows, now the 【Menu】 key does emacs's “execute-extended-command”,
just like emacs on linux's default behavior. Rational: This is better than the 【Alt+a】. Because 【a】 is pinky, and it involves 2 keys. Now it's single key. Also, this makes it compatible with emacs on linux .
*** interactive search (“isearch-forward”) is now QWERTY 【y】
, instead of 【;】.
Rational: this is a highly frequently used command. 【;】 is on home-row, but by pinky. 【y】 is far, but by strong finger. Reaching for y may be a fraction of second slower, but more comfortable and healthy than using pinky.
*** 【Ctrl+f】 is now interactive search (“isearch-forward”).
(was “search-forward”)
Feature incomplete. Need to add repeated 【Ctrl+f】 to invoke next match.
*** added more than 10 additional keys starting with function keys.
【F1 1】 describe-function
【F1 2】 describe-variable
【F1 3】 describe-key
【F1 4】 describe-char
【F1 6】 lookup-all-dictionaries
【F1 7】 lookup-google
【F1 8】 lookup-wikipedia
【F1 9】 lookup-word-definition
【F1 0】 lookup-answers.com
【F1 [】 lookup-word-dict-org
【F1 ]】 lookup-wiktionary
【F1 `】 elisp-index-search
【F2】 ,cut
【F3】 ,copy; 【Ctrl+F3】 ,copy-all
【F4】 ,paste
【F5】 ,undo; 【Ctrl+F5】 ,redo
【F8】 ,ctl-x-map. Emacs's C-x prefix key.
Rational: these are single key or single key sequence additional keys. The copy, cut, paste, undo, ones are frequently used. Single key is good. The F8 is a additional key for emacs combo key C-x. The F1 key sequences adds many convenient or helpful commands.
** version 5.4.4, 2012-05-12
*** added 【F1+m】 for “describe-major-mode” and 【F1+o】 for “where-is-old-binding”. Rationale: keep in sync with the 【F1】 = 【Ctrl+h】 equivalence.
** version 5.4.3, 2012-04-29
*** Removed 【Ctrl+Shift+w】 for “delete-frame” (close current window).
rationale: Close Current Window should really follow OS's key convention. Or, in ErgoEmacs, 【Alt+F4】 does it. This way, it's more standard. Less keys.
On the Mac, current behavior is ok too.
The reason for a 【Ctrl+Shift+w】 for closing window doesn't seem strong.
*** If inside minibuffer, “close-current-buffer” now do do nothing.
Fixed bug #92 http://code.google.com/p/ergoemacs/issues/detail?id=92
Previously, it prompt if user want to save, etc.
Thanks to dek1999@live.com
** version 5.4.2, 2012-04-11
Fixed “open-in-external-app”. Before, on linux, emacs freezes until external app is closed. Thanks to Thanks to Ozan Erdem.
** version 5.4.1, 2012-04-09
trivial changes.
*** fixed a leaked variable “item” in 〔ergoemacs-unbind.el〕.
*** updated 〔_INSTALL.txt〕.
*** updated a few files that points to the dead 〔http://tecladobrasileiro.com.br/〕 to 〔http://xahlee.org/kbd/pt-nativo_keyboard_layout.html〕
** version 5.4.0, 2012-03-03
*** 2012-03-03 Added a command “open-in-external-app”. The key 【Ctrl+Shift+o】 is now bound to it, instead of “open-in-desktop”.
*** 2011-11-22 GNU emacs's 【C-x d】 for “dired” is no longer unbound (it's available now).
Originally, it's unbound because the thought was that 【Ctrl+o】 for “find-file” with a dir input is a good clean substitute. But now, i think in some situations, calling dired directly is necessary. For example, calling dired then give “~/emacs/*.html” to list all HTML files. If using “find-file”, it'll try to open all files.
Now, since it's necessary to call “dired” directly sometimes, it's convenient to have a key. Since GNU Emacs already has 【C-x d】 for it, and this key doesn't conflict with ErgoEmacs, so we use it.
Thanks to Joseph Buchignani

*** 2011-11-18 minor improvement on “toggle-letter-case”. Now better guess at initial state.
** version 5.3.9, 2011-04-17
*** 2011-04-17 Fixed shift key selection with cua-mode
r647
Fixed a bug
http://code.google.com/p/ergoemacs/issues/detail?id=91
with a default GNU Emacs, when cua-mode is NOT turned on, load ergoemacs-mode and turn it on, then keys with Shift will also highlight text. This is because ergoemacs-fix-cua--pre-command-handler-1 tries to set symbols from cua-mode but they are not there.
thanks to (zyangm...@gmail.com) for bug report.
fixed by temp turning on cua-mode.
*** 2011-03-22 Added a compatibility fix for auto-complete-mode
Added a ergoemacs-auto-complete-mode-hook.
http://code.google.com/p/ergoemacs/source/detail?r=638
Thanks to Renier (renierm@gmail.com) for code. http://groups.google.com/group/ergoemacs/msg/f5f9337e34b4eab3?hl=en
*** 2010-11-18 added a hotkey 【Ctrl+Shift+t】 for open-last-closed
r556
This key follows browser convention. But won't work in Terminal.
*** 2010-12-10 copy/cut with no text selection will include the line ending.
r578.
Thanks to Max Arnold for bug report.
** version 5.3.7, 2010-11-15
*** Added open-in-desktop command with key 【Ctrl+Shift+o】.
*** Added open-last-closed command.
*** More international layouts
Added Danish layout. Thanks to Michael Budde
Added ergoemacs-layout-pt-nativo.el. Thanks to Xavier Pinho
You can see all supported layouts and their contributors in the directory 〔ergoemacs-keybindings〕.
See also: 〈Dvorak, Maltron, Colemak, NEO, Bépo, Turkish-F, Keyboard Layouts Fight!〉 @ http://xahlee.org/kbd/dvorak_and_all_keyboard_layouts.html
*** minor fixes
**** 【Ctrl+Backspace】 for backward-kill-word
This is a standard key together with 【Ctrl+Arrow】 and 【Ctrl+Del】.
r477 Technically, removed the unbinding of 「」
**** Added ergoemacs-keyboard-quit-key to ergoemacs-layout-gb.el
A bug fix. Thanks to Jorge Dias.
** version 5.3.4, 2010-08-16
*** Added a Swedish layout
Contributed by Kristian Hellquist.
*** remapped split window keys for all layouts.
OLD COMMAND NEW
【Alt+1】 delete-other-windows 【Alt+3】
【Alt+!】 delete-window 【Alt+0】
【Alt+2】 split-window-vertically 【Alt+4】
【Alt+@】 split-window-horizontally 【Alt+$】
Reason: the 1 and 2 keys are two of the most difficult to press keys on the top row.
3 and 4 are the best for left hand.
8 and 9 are the best for right hand.
(this can be verified by looking at the original Dvorak layout for number keys)
For emacs commands, according to command frequency statistics, the order are roughly this, from most used to least:
delete-other-windows
split-window-vertically
delete-window
split-window-horizontally
therefore this change. For Xah Lee's personal experience in this, see:
http://xahlee.org/emacs/vi_esc_syndrome.html
Note that 【Alt+0】 for delete-window was in the original ErgoEmacs keybinding design for about a year, but got changed to 【Alt+Shift+1】 (【Alt+!】). The thinking was for some logical consistency with 【Alt+1】. My experience since is that logical consistency is bad for ergonomics advantage. Logical consistency is good at beginning for learning, but once muscle memory is developed, ergonomic efficiency is far more important, and will be used for years.
** version 5.3.3, 2010-05-24
*** 【Ctrl+p】 now asks for confirmation before printing
【Ctrl+p】 will now ask user confirmation before printing the current buffer.
This is to prevent unintentional printing.
Old Emacs users tends to press 【Ctrl+p】 a lot because that used to be moving cursor up.
See: http://code.google.com/p/ergoemacs/issues/detail?id=60
** version 5.3.2, 2010-05-22
*** Added United Kingdom layout (gb).
Thanks to Jorge Dias (aka theturingmachine)
http://code.google.com/p/ergoemacs/source/detail?r=371
http://groups.google.com/group/ergoemacs/browse_frm/thread/3e1b9326b6cc2cc4
*** Added United Kingdom Dvorak layout (gb-dv).
Thanks to Phillip Wood
http://code.google.com/p/ergoemacs/issues/detail?id=73
*** fixed keybinding conflict problem. You can now change bindings
by David Capello. (and thanks to maddin)
Added ergoemacs-hook-list variable, ergoemacs-add-hook function, and ergoemacs-global/local-set/unset-key functions
and added “defadvice” for local/global-set/unset-key functions. http://code.google.com/p/ergoemacs/source/detail?r=369
http://code.google.com/p/ergoemacs/issues/detail?id=67#c3
*** Copy and Cut to copy/cut current line
Added a feature so that copy/cut will get the current line if there's no text selection.
** version 5.x.x
Italian layout has been created, by By David Capello, with help by Francesco Biccari
A Colemak layout is added or sometimes before. The bulk of key mapping was helped by Ivan Haralamov (aka postivan), and vockets?
** version 5, 2009-09-15
*** Changed into a minor mode, with support for many keyboard layouts
By David Capello.
This version is now a full featured minor mode. It supports 3 different keyboard layout: US QWERTY, US Dvorak, and “Spanish (Spain)” (aka “Spanish (International sort)”). Also supports a new command where-is-old-binding (with shortcut 【Ctrl+h o】).
** version 4.3.13, 2009-08-28
*** improved shrink-whitespaces. Now, when called twice, it removes the remaining single space. Thanks to David Capello for the code.
** version 4.3.12.2, 2009-08-15
*** Fixed a bug where delete-selection-mode might be turned off. Changed “(delete-selection-mode t)” to “(delete-selection-mode 1)”.
** version 4.3.12.1, 2009-08-14
*** A minor implementation improvement. In one place, changed the use of functionp to fboundp for checking the existing of a emacs 23 feature recenter-top-bottom. Was using functionp because i forgot about fboundp.
** version 4.3.12, 2009-08-13
*** 【Alt+p】 is now “recenter-top-bottom” for emacs 23 users. In emacs 22, it is “recenter”.
** version 4.3.11, 2009-08-05
*** Added a hook to fix message-mode.
** version 4.3.10, 2009-06-14
*** fixed a previous/next reversal for f11/f12 keys in rcirc-mode-hook.
*** diff-mode uses some bindings in “M-‹key›” space. Fixed by adding a diff-mode-hook. (thanks to lwarxx)
** version 4.3.9, 2009-06-14
*** unbind 「C-x 3」 (use 【Alt+@】 for split-window-horizontally)
*** unbind 「C-M-%」 (use 【Alt+%】 for query-replace-regexp).
*** unbind 「C-@」 (use 【Alt+Space】 for set-mark-command).
*** unbind 「M-{」 (use 【Alt+u】 for backward-paragraph).
*** unbind 「M-}」 (use 【Alt+o】 for forward-paragraph). Thanks to marciomazza
** version 4.3.8, 2009-06-14
*** added 【Alt+7】 to select-text-in-quote.
** version 4.3.7, 2009-05-27
*** ibuffer's 「M-s」 changed in emacs 23, such that 「M-s」 is now a prefix. For Dvorak users, 「M-s」 should be isearch. This is reclaimed to be isearch. For qwerty users, 「M-s」 should be other-window. Fixed.
** version 4.3.6, 2009-05-26
*** dired's 「M-s」 changed in emacs 23, such that 「M-s」 is now a prefix. For Dvorak users, 「M-s」 should be isearch. This is reclaimed to be isearch. For qwerty users, 「M-s」 should be other-windox. Fixed.
** version 4.3.5, 2009-05-10
*** experimental modification to shrink-whitespaces.
** version 4.3.4, 2009-04-19

*** Removed 「C-x o」 for other-window. (use 【Alt+s】 and 【Alt+Shift+s】 instead.)
** version 4.3.1, 2009-03-04
*** A better implementation for making 「M-t」 call 「M-TAB」. So that, describe-key on M-t will show better documentation.
** version 4.3.0, 2009-03-02
*** Added 【Alt+Shift+x】 for cut-all and 【Alt+Shift+c】 for copy-all.
** version 4.2.4, 2009-03-01
*** Removed 【Ctrl+x Ctrl+w】 for write-file. Use 【Ctrl+Shift+s】.
*** Fixed 【Ctrl+o】 for ibuffer to run find-file instead of ibuffer-visit-buffer-other-window-noselect.
** version 4.2.3, 2009-03-01
*** fixed a dired binding so that 【Ctrl+o】 runs find-file instead of dired-display-file
** version 4.2.2, 2009-03-01
*** Removed the default keybinding for split-window-vertically 【Ctrl+x 2】. Use 【Alt+2】 instead.
*** The key 【Ctrl+x Ctrl+b】 is now ibuffer, instead of list-buffers.
*** 【Ctrl+h m】 now calls describe-major-mode.
** version 4.2.1, 2009-02-28
Changed the keybinding for previous-user-buffer from 【Ctrl+←】 to
【Ctrl+PageUp】. And previous-emacs-buffer from 【Ctrl+Shift+←】 to
【Ctrl+Shift+PageUp】. Similar for the “next” versions. Rationale: The
【Ctrl+Arrow】 are standard editing shortcuts command in Windows, Mac,
Linux.
** version 4.2.0, 2009-02-27
Added 【Alt+t】 for keyword completion. Rationale: The default 「M-TAB」 is used by Windows, Mac, Linux, to switch apps.
** version 4.1.8, 2009-02-15
Corrected the keybinding for Save As (write-file)
** version 4.1.7, 2008-12-10
Made compact-uncompact-block to work on text selection if there's one.
** version 4.1.6, 2008-12-09

Sometimes when closing a buffer not associated with a file, it'll prompt whether to kill instead of whether to save.
** version 4.1.3, 2008-10-18
*** Fixed minor bug in toggle-letter-case.
It now works non-english letters such as éÉ and single letter word “a teapot” or words starting with a number “1st timer”. Thanks to Andreas Politz and Nikolaj Schumacher.

*** Removed unfill-paragraph and unfill-region
Because they are defined in ourcomments-util.el bundled with emacs 22, also because they are not used in this file now (compact-uncompact-block replaced most of their functionality).
** version 4.1, 2008-10-06
*** Added keys for about 9 commands
previous-user-buffer, next-user-buffer, next-frame-command, previous-frame-command, query-replace and query-replace-regexp, move-cursor-to-next-pane, move-cursor-to-previous-pane, split-window-horizontally, toggle-letter-case. Combined delete-blank-lines and just-one-space to shrink-whitespaces.

*** Features
Currently ergoemacs-mode:
- Changes the default emacs keybindings in two ways:
- To be more ergonomic by binding frequently used commands to easy
to reach keys
- Implement [[file:standard-shortcuts.html][standard keyboard shortcuts]] in emacs.
- Allows keyboard themes for:
- [[file:gradual-adoption.html][Gradual ergoemacs-adoption]]
- Backward Compatability
- Ergonomic personalization
** Design Basis
:PROPERTIES:
:PAGE: design-basis.html
:TEMPLATE: blog_static_no_title.html
:END:
Here's the outline of how this design is arrived.
Statistics of emacs commands are compiled from emacs users, and are
listed by frequency of use. The top about 30 ones, are given a
keyboard shortcut.
To assign the key position, the following rules are used. The rules
are listed roughly in order of priority:
1. Home row keys are the best.
2. 2nd and 3rd fingers (pointing finger and index finger) are better
than 4th (ring finger) and 5th finger (pinky).
3. The row above home row is considered better than the row below home
row for 2nd and 3rd fingers. (for 5th finger the row below is
considered better.)
4. Right hand's keys are considered better than left hand's keys. (because most people are right handed)
5. @@html:@@Alt@@html: @@ is considered better
than @@html:@@Ctrl@@html: @@. (@@html:@@Alt@@html: @@
is a natural thumb curl, @@html:@@Ctrl@@html: @@ is
stretched pinky. Thumb is most powerful finger, pinkie the weakest)
6. In general, cursor moving commands are placed all for the right
hand, while text changing commands are all placed for the left
hand. (grouping advantage)
7. Similar commands should be grouped together to avoid
scattering. For example, cursor moving by single char is together
(@@html:@@I@@html: @@ @@html:@@J@@html: @@ @@html:@@K@@html: @@ @@html:@@L@@html: @@). Undo, Cut, Copy, Paste are together (@@html:@@Z@@html: @@ @@html:@@X@@html: @@ @@html:@@C@@html: @@ @@html:@@V@@html: @@). Delete
char/word left/right are together (@@html:@@E@@html: @@ @@html:@@R@@html: @@ @@html:@@D@@html: @@ @@html:@@F@@html: @@).
8. Commands with logical reversal or extension are done with @@html:@@⇧ Shift@@html: @@
key, after other priorities are considered. Examples: Undo/Redo,
move cursor to previous/next pane, find replace by string/regex,
isearch forward/backward, move cursor by beginning/ending of
line. Delete line to the right/left.
The design is based on finger positions, not on first letter of
command names. The shortcut set is the same for QWERTY and Dvorak. The
ease of remembering what commands are on what keys are based on
grouping and positioning. For example, cursor movings are all right
hand, text changing are all left hand, moving or deleting to the
left/right have keys that are place left and right together, and
similar for up/down (by screen or to beginning/end of file). Undo,
Cut, Copy, Paste are the familiar row @@html:@@Z@@html: @@ @@html:@@X@@html: @@ @@html:@@C@@html: @@ @@html:@@V@@html: @@.
In this design, only the @@html:@@Alt@@html: @@+@@html:@@‹key›@@html: @@ space is used. Some @@html:@@Alt@@html: @@+@@html:@@⇧ Shift@@html: @@
is used too. @@html:@@Ctrl@@html: @@+@@html:@@‹key›@@html: @@ space is not used except 7 standard
keybindings (Open, Close, Save, Save As, Print, Select All). The
operation and consistency of emacs is not affected.
** Standard Shortcuts
:PROPERTIES:
:PAGE: standard-shortcuts.html
:TEMPLATE: blog_static_no_title.html
:END:
This shows the standard shortcuts implemented in ergoemacs:
|---------------+--------------------------+------------------+---------------------|
| Standard Name | Ergoemacs-key | Emacs Key | Emacs Command Name |
|---------------+--------------------------+------------------+---------------------|
| Copy | Ctrl+c | Alt+w | =kill-ring-save= |
| Cut | Ctrl+x | Ctl+w | =kill-region= |
| Paste | Ctrl+v | Ctrl+y | =yank= |
| Undo | Ctrl+z | Ctrl+_ or Ctrl+/ | =undo= |
| Redo | Ctrl+⇧ Shift+z or Ctrl+y | NA | =redo= |
| Open New File | Ctrl+n | NA | Not builtin |
| Open | Ctrl+o | Ctrl+x Ctrl+f | =find-file= |
| Print | Ctrl+p | NA | |
| Select All | Ctrl+a | | =mark-whole-buffer= |
| Find | Ctrl+f | Ctrl+s | =search-forward= |
|---------------+--------------------------+------------------+---------------------|
Standard shortcuts for cursor navigation are also supported. For example:
- Ctrl+← ⇒ move cursor to to previous word.
- @@html:@@Home@@html: @@ ⇒ move cursor to beginning of
- Shift+↓ select text downward.
** Preserving Emacs Commands while maintaining familiar shortcuts
:PROPERTIES:
:PAGE: cua-conflict.html
:TEMPLATE: blog_static_no_title.html
:END:
*** Conflict for Emacs command keys and familiar shortcuts
There is a conflict between standard shortcuts and emacs shortcuts.
In most applications Ctrl+c is copy and Ctrl+x is cut. In emacs
Ctrl+x generally refer to global commands, while Ctrl+c refers to
language specific commands.
Ergoemacs provides a few options to work with the Ctl+c and Ctl+x keys.
**** Binding Ctrl+c and Ctrl+x to both copy and cut and emacs keys
Like =cua-mode=, =ergoemacs-mode= allows Ctrl+c and Ctrl+x to be
bound to both copy/cut, and the emacs key sequences.
The default method will copy text when selected with Ctrl+c and cut
text when selected with Ctrl+x. This is fine, but if you wish to
perform an emacs command on selected region, this could be problematic
as discussed in Xah's [[http://ergoemacs.org/misc/emacs_keybinding_and_cua-mode_keys.html][blog]]. (For example python shift indent is bound
to 【Ctrl+c <】)
When you wish to do issue emacs commands on a region you can:
- Add a shift to the first Ctrl+c and Ctrl+x.
- For example press 【Ctrl+⇧ Shift+c <】 for python's shift indent
command
- This will not work in a terminal (most terminals cannot tell the
difference between 【Ctrl+⇧ Shift+c】 and 【Ctrl+c】)
- Press the next key within 0.2 seconds.
- This can be tuned by setting =ergoemacs-ctl-c-or-ctl-x-delay=
- If you tune this to a higher setting, it takes longer to copy and
cut and other problems may be introduced.
If you wanted the time required to press the next key be 1 second,
you could use the following in your emacs startup file:
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-ctl-c-or-ctl-x-delay 1)
#+END_SRC
**** Binding Ctrl+c and Ctrl+x to emacs commands only
Another option is to ditch copy and paste with Ctrl+c and Ctrl+x, even
though they are standard keys. Instead you can use Alt+c and Alt+x to
do copy and paste.
This can be done in ergoemacs by the following variable:
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-handle-ctl-c-or-ctl-x 'only-C-c-and-C-x)
#+END_SRC
The disadvantage to this approach is that you use different keys in
different applications.
**** Binding Ctrl+c and Ctrl+x to only copy and cut
If you wanted Ctrl+c and Ctrl+x to only be copy and cut, you add
the ability to copy/cut the current line when nothing is selected.
This can be done by:
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-handle-ctl-c-or-ctl-x 'only-copy-cut)
#+END_SRC
The possible disadvantage to this is you would have to use another key
to access the defined emacs commands. Currently ergoemacs-mode allows
you to use QWERTY 【▤ Menu d】 or 【Ctrl+⇧ Shift+x】 to access emacs
Ctrl+x commands and QWERTY 【▤ Menu f】 or 【Ctrl+⇧ Shift+c】 to
access Ctrl+c commands.
The 【▤ Menu】 keybindings are slightly different than plan Ctrl+x or
Ctrl+c:
- For Ctrl+x, the Alt and Ctrl keys are swapped. Hence for the
equivalent of 【Ctrl+x Ctrl+b】, you would press 【▤ Menu s Alt+b】
- For Ctrl+c, control keys are mapped to plain keys. Plain keys
are mapped to Alt keys. Alt keys are mapped to Ctl keys. Hence:
- 【Ctrl+c Ctrl+c】 would be 【▤ Menu f c】
- 【Ctrl+c c】 would be 【▤ Menu f Alt+c】
- 【Ctrl+c Alt+c】 would be 【▤ Menu f Ctl+c】
- This is called unchorded mapping
- You can swap between Normal, Alt<->Ctl and unchorded keyboard
translations in ergoemacs by pressing 【▤ Menu】
** Included Key Themes and Layouts
:PROPERTIES:
:PAGE: key-setup.html
:TEMPLATE: blog_static_no_title.html

*** Supported Key Themes and Keyboard Layouts
To use key theme and layout, use the following in your =.emacs= or
=.emacs.d/init.el=.
#+ATTR_HTML :id dot_emacs
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-theme nil)

** Setting your own keys
:PROPERTIES:
:PAGE: own-keys.html
:TEMPLATE: blog_static_no_title.html
:END:
Emacs has its own methods to set keys globally. Ergoemacs-mode
attempts to honor this.
** Key Themes
:PROPERTIES:
:PAGE: key-themes.html
:TEMPLATE: blog_static_no_title.html
:END:
*** Why key themes?
Key themes are a big part of the new ergoemacs-mode. These allow
more than one keyboard binding to be packaged but still use the
ergoemacs-mode engine. This allows:
- [[file:gradual-adoption.html][Gradual ergoemacs-adoption]]
- Backward Compatability
- Sharing of your personalized ergoemacs-theme
- Keeping ergoemacs compatibility fixes such as:
- Using the arrow keys in the terminal when Alt+O or Alt+o is bound
- Providing fixes for known minor and major modes so they respect
the ergonomic keyset.
- Keeping some additional ergoemacs features like:
- Applying your personalied ergoemacs-theme [[file:system-wide.html][everywhere]]
*** Creating your own ergoemacs theme
You can manually code your own ergoemacs theme. I am currently
working on a simlper method to theme keys.
** Keyboard Layouts
:PROPERTIES:
:PAGE: keyboard-layouts.html
:TEMPLATE: blog_static_no_title.html
:END:
All the layouts in ergoemacs are easy to generate. To add your own
personal layout you just need to match the keybindings for your in a
layout variable from =ergoemacs-layout-XXX=. For the US and UK
layouts, the defining variable adds the layout:
#+BEGIN_SRC emacs-lisp

This lists the keyboard positions from left to right for the unshifted
and shifted states of he keyboard. After listing the keyboard
descriptions it provides a description of the layout which is used for
the customization variable `ergoemacs-keyboard-layout'. By simply
defining your layout before ergoemacs-mode is loaded, you add it to
the ergoemacs-keyboard-layout variable with its description.
If you have generated a keyboard layout that ergoemacs-mode does not yet
support please [[https://github.com/ergoemacs/ergoemacs-mode/issues/new][drop me a line]].
** Changes to Modes
:PROPERTIES:
:PAGE: minor-modes.html
:TEMPLATE: blog_static_no_title.html
:END:
Most major and minor modes are setup to respect =ergoemacs-mode=
keybindings. There are additional changes described below
*** Org mode
Ergoemacs-mode in general respects org-mode's Ctrl+Enter and Alt+arrow
keys. The following exceptions are of note:
**** Ctrl+Enter in tables
In org-mode tables Ctrl+enter activates cua rectangle mode. The
paste knows what was copied, and will use cua-mode, or org-mode's
default pasting mechanism depending on if a rectangle was copied last.
**** Alt+arrow keys
The alt+arrow keys are respected based on context for org-mode. When
in text, you can use the ergoemacs-mode defined key, or the org-mode
defined key by changing the value of a few variables
|-----------+--------------------------------------------------------+--------------------|
| Key | Variable to Enable ergoemacs function in org-mode text | Enabled by default |
|-----------+--------------------------------------------------------+--------------------|
| | ergoemacs-use-ergoemacs-metaleft | yes |
| | ergoemacs-use-ergoemacs-metaright | yes |
| | ergoemacs-use-ergoemacs-metaup | no |
| | ergoemacs-use-ergoemacs-metadown | no |
|-----------+--------------------------------------------------------+--------------------|
The values of these variables could be changed by:
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-use-ergoemacs-metaleft nil)
#+END_SRC
*** Cua-mode
Cua mode is not enabled by default, but ergoemacs-mode can use some of
its features. To enable CUA rectangles, use:
#+BEGIN_SRC emacs-lisp
(cua-selection-mode t)
#+END_SRC
If =cua-mode= is enabled before =ergoemacs-mode= is loaded,
=ergoemacs-mode= changes to =cua-selection-mode=. If you attempt to
enable =cua-mode=, only =cua-selection-mode= will be enabled.
CUA rectangle support is enabled by changing the Alt+
keys to Win+ keys.
If you do not know what CUA rectangles are, the following describes
CUA rectangles and gives the keys used for ergoemacs-mode.
**** Rectangle support
Cua-mode's rectangle select region has bound it
Emacs's normal rectangle support is based on interpreting the region
between the mark and point as a "virtual rectangle", and using a
completely separate set of "rectangle commands" [C-x r ...] on the
region to copy, kill, fill a.s.o. the virtual rectangle.
cua-mode's superior rectangle support uses a true visual
representation of the selected rectangle, i.e. it highlights the
actual part of the buffer that is currently selected as part of the
rectangle. Unlike emacs' traditional rectangle commands, the
selected rectangle always as straight left and right edges, even
when those are in the middle of a TAB character or beyond the end
of the current line. And it does this without actually modifying
the buffer contents (it uses display overlays to visualize the
virtual dimensions of the rectangle).
This means that cua-mode's rectangles are not limited to the actual
contents of the buffer, so if the cursor is currently at the end of a
short line, you can still extend the rectangle to include more columns
of longer lines in the same rectangle. And you can also have the
left edge of a rectangle start in the middle of a TAB character.
Sounds strange? Try it!
To start a rectangle, use [C-return] and extend it using the normal
movement keys (up, down, left, right, home, end, C-home,
C-end). Once the rectangle has the desired size, you can cut or
copy it using C-x and C-c (or C-w and M-w), and you can
subsequently insert it - as a rectangle - using C-v (or C-y). So
the only new command you need to know to work with cua-mode
rectangles is C-return!
Normally, when you paste a rectangle using C-v (C-y), each line of
the rectangle is inserted into the existing lines in the buffer.
If overwrite-mode is active when you paste a rectangle, it is
inserted as normal (multi-line) text.
If you prefer the traditional rectangle marking (i.e. don't want
straight edges), [M-p] toggles this for the current rectangle,
or you can customize cua-virtual-rectangle-edges.
And there's more: If you want to extend or reduce the size of the
rectangle in one of the other corners of the rectangle, just use
[return] to move the cursor to the "next" corner. Or you can use
the [M-up], [M-down], [M-left], and [M-right] keys to move the
entire rectangle overlay (but not the contents) in the given
direction.
[C-return] cancels the rectangle
[C-space] activates the region bounded by the rectangle
If you type a normal (self-inserting) character when the rectangle is
active, the character is inserted on the "current side" of every line
of the rectangle. The "current side" is the side on which the cursor
is currently located. If the rectangle is only 1 column wide,
insertion will be performed to the left when the cursor is at the
bottom of the rectangle. So, for example, to comment out an entire
paragraph like this one, just place the cursor on the first character
of the first line, and enter the following:
C-return M-} ; ; C-return
cua-mode's rectangle support also includes all the normal rectangle
functions with easy access:
[Win+a] aligns all words at the left edge of the rectangle
[Win+b] fills the rectangle with blanks (tabs and spaces)
[Win+c] closes the rectangle by removing all blanks at the left edge
of the rectangle
[Win+f] fills the rectangle with a single character (prompt)
[Win+i] increases the first number found on each line of the rectangle

writable dired mode (wdired-mode). Then [Ctrl+c] [Ctrl+c] or [Apps]
[m] will commit the changes.
*** Helm-mode
Helm mode's actions are in general executed with the Return key. The
persistent actions can be executed with Alt+Return. The prefix-based
persistent actions can be execute with Alt+Shift+Return.
The exception to this is when finding files. Return will expand the
directory within helm (equivalent to helm's execute persistent action
for a directory). And Alt+Return will open dired. This is equivalent
to ido-mode. In my opinion it is more likely that you want to do
than to open in ido-mode. Therefore an unchorded key is more
ergonomic than a key combination like Alt+Return. However, you can
turn off this behavior by changing the following setting:
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-helm-ido-style-return nil)
#+END_SRC
*** Visual Regexp
When [[https://github.com/benma/visual-regexp.el][visual regexp]] is installed, ergoemacs-mode changes
=query-replace-regexp= to =vr/query-replace=
*** Browse-kill-ring and pasting
The package =browse-kill-ring= can be integrated into the way that
ergoemacs-mode pastes. For information see

** Icicles with ergoemacs-mode
:PROPERTIES:
:PAGE: icy-mode.html
:TEMPLATE: blog_static_no_title.html
:END:
*Authors:* Nikolay Kudryavtsev and Matthew L Fidler
Icicles is a complicated library with many different
keybindings. Ergoemacs also has quite few keybindings of it's
own. Since both packages were originally developed separately it is
understandable that there can be a conflict between them. This
documentation lists the known cases of conflict.
*** Things that work differently with ergoemacs
**** Icicle history element cycling is moved to F11 and F12
Icicles uses M-p and M-n for `icicle-previous-history-element` and
`icicle-next-history-element`. Since those are perfect examples of
non-ergonomic keys, ergoemacs changes them to F11 and F12. This is
consistent with changes to other packages.
**** Icicles insert history element with M-F11 or M-F12
In icicles you can [[http://www.emacswiki.org/emacs/Icicles_-_History_Enhancements#toc4][insert an element from your minibuffer history]],
thus limiting your candidates only to the ones in your minibuffer
history. In `ergoemacs-mode` This can be done by M-F11 or M-F12.
**** Icicles candiate cycling is moved to QWERTY M-i and M-k
In the vanila icicles `icicle-previous-candidate-per-mode` and
`icicles-next-candidate-per-mode` are cycled using C-p and C-n. This
is not ergonomic, so in ergoemacs it was moved to M-i and M-k.
Whenever icicles binds a standard key like C-p or C-n, or C-s,
ergoemacs-mode looks up the change and runs the mode-based changed
key.
**** Key Completion
In icicles you can [[http://www.emacswiki.org/emacs/Icicles_-_Key_Completion][easily see all available keys using key
completion]]. The default key for this is S-TAB for buffers and M-S-TAB
for the minibuffer. Due to M-TAB being used by default by some window
managers including Windows, ESC-S-TAB is also available by
default. Since ESC works like C-g in ergoemacs, ESC-S-TAB binding
would not work with it.
When icicles and ergoemacs-mode is enabled, pressing f1 in the key
sequence will start the key completion.
*** Things that do not work with ergoemacs out of box
Things here conflict with some ergoemacs keybindings, but can be
easily fixed by the user.
**** How to redifine keys from icicles
The most basic ergoemacs theme component for icicles looks like
this. Since most of the icicles keybindings are connected to
minibufer, you should put your keybindings within "when
`icicle-minibuffer-setup-hook`" form.
#+BEGIN_SRC emacs-lisp
(ergoemacs-component ergoemacs-icicles-user ()
"Ergoemacs-mode theme component for icicles"
(when icicle-minibuffer-setup-hook
(define-key minibuffer-local-map (kbd "M-p") 'icicle-insert-history-element)))
(ergoemacs-require 'ergoemacs-icicles-user)
#+END_SRC
**** C-M-j - icicle-insert-list-join-string
Icicles [[http://www.emacswiki.org/emacs/Icicles_-_Multi-Completions#toc2][allows you to match only those candidates that have particular
text within them]]. A rather complex example is available [[http://www.emacswiki.org/emacs/Icicles_-_Nutshell_View#toc6][here]].
***** How to fix
C-M-h is a good candidate, since it's close enough to the original
key, but does not conflict with ergoemacs:
#+BEGIN_SRC emacs-lisp
(define-key minibuffer-local-map (kbd "C-M-h") 'icicle-insert-list-join-string)
#+END_SRC
** Bug report

Before reporting a bug, please check if it is already known about.
Indeed, it may already have been fixed in a later release of
=ergoemacs-mode=, or in the development version. Here is the issues
list: https://github.com/ergoemacs/ergoemacs-mode/issues
If you are able to, try the latest =ergoemacs-mode= to see if the
problem has already been fixed.
To report a bug please be sure your issue is =ergoemacs-mode= related.
An easy way to do that is to get a clean environment to see if you can
reproduce the error. If you can load ergoemacs, then this can be
accomplished by Alt+a =ergoemacs-clean=.
Otherwise, this can be accomplished by
#+BEGIN_SRC sh
emacs -Q
#+END_SRC
Then in the =*scratch*= buffer adding
#+BEGIN_SRC emacs-lisp
(setq debug-on-error t) ; Activate debugging
(add-to-list 'load-path "/path/to/ergoemacs/")
(require 'ergoemacs-mode)
(setq ergoemacs-debug t)
(setq ergoemacs-keyboard-layout "us") ; Layout you use.
(setq ergoemacs-theme nil) ; For standard theme.
(ergoemacs-mode 1)
#+END_SRC
Then type Alt+x =eval-buffer=.
See if you can reproduce the bug from this empty environment. If you
can reproduce the bug this way, that rules out bugs in your personal
customizations. Then your bug report should begin by stating that you
started Emacs with =emacs -Q=, followed by the exact sequence of steps
for reproducing the bug. If possible, inform us of the exact contents
of any file that is needed to reproduce the bug.
When you hit an error, a =*Backtrace*= buffer will appear on the
screen. Save this buffer to a file and attach it to your bug report.
Please report documentation bug too.

#+begin_quote
After some 30 years of using Emacs constantly, I recently switched
from using Microsoft keyboards (of various sorts) to using Apple
keyboards. Needless to say, Emacs Pinky arose and I found myself
consuming most all of what Xah Lee has written in the area of using
Emacs ergonomically with Apple keyboards. Most impressive material.
Being a bleeding edge Emacs User (and occasional developer, although
it embarrasses me to think about how long it has been since I made any
substantial contributions), I use the development nightly builds as a
matter of course. So when I bit the bullet and installed ErgoEmacs,
my instance blew up (in that nothing worked as expected) and I decided
to back off a bit from going whole hog. [Mea culpa, but I did not
have the time to debug the problems. At least not yet.]
To make a long story shorter, I embraced the notion of remapping keys
to use the recommended ErgoEmacs layout, but tried to shortcut the
process by turning "caps lock" into a "menu" key and creating key
sequences that were productive for me; remapping the "control" key to
"command", the "option" keys to "control" and the "command" keys to
"option". But I did not take the pains of programmatically changing
the key bindings for other packages (like org-mode) so I quickly ran
into hassles.
To resolve the issue of other package interference with the ErgoEmacs
keybindings I used (on Meta), I switched back to using the Mac default
modifier keys and mapped the ErgoEmacs bindings to the "command" keys
via Super.
One of Xah's best suggestions for me was the notion of "curled thumbs"
to symmetrically type the Super keys. That has been a huge win, both
in eliminating Emacs Pinky and improving my typing productivity. Who
knew? :-)
I am still a bit anxious that OS X will intervene on some of my
rebindings with the "command" key in particular but so far so good.
In all of this work that I've done, the major factor has been
significantly reducing the need to use C- and M- chords and
instead using "menu" key sequences and s- chords.
Another factor has been standardizing on the short Apple keyboard (the
one found on recent Apple laptops) which I once hated because of the
lack of "control" key symmetry. I found that once I started using
curled thumbs for chords, the short keyboard actually worked quite
well for me. Especially since I use some half dozen MacBook Air/Pro
laptops and Mac Mini systems on a regular basis.
There are probably a few other steps taken that I have forgotten but I
think this captures most of a positive experience in embracing
ErgoEmacs keyboarding.
fwiw,
-pmr

I've just found ErgoEmacs (http://ergoemacs.org), another Emacs distribution for Windows that tries to make Emacs easy to use for ordinary users… and it does so: I was able to use it immediately, with all the standard Windows shortcuts--the only things that tripped me up briefly were the file commands (C-xf moved to C-o and C-xw moved to C-w), and that they moved M-x to M-a (M-x now cuts the entire line). This looks like a distro that might ease the learning curve enough to drive more widespread adoption of Emacs (and org-mode!): it really does seem to be as easy to use as Notepad right out of the box, yet doesn't take away any of the power of Emacs (as far as I can tell, except that I did have to load an org-mode file before capture would work, but that may be a setup problem on my part). If you're on Windows, take a look and see what you think… and for org newbies on win32, I think this is the version I would recommend.

ErgoEmacs 初探
一直以來,我都是從 Xah's Emacs Tutorial 獲得一些 Emacs 使用上的小技巧。前幾天突然發現 Xah Lee 弄了一個專案 --- ErgoEmacs。一個很有趣的專案,同時也是破壞 Emacs 傳統的專案。
Emacs 專屬的 keybindings 可以說是一項足以自豪的傳統。對於那些不使用滑鼠的高手來說,keybindings 一定背的滾瓜瀾熟。但非人使用 Emacs 超過十年了,熟悉的 keybindings 不會多過 10 個。並不是非人不想背下來,而是太複雜了,今天背了明天就忘了。再加上非人非常地依賴滑鼠,所以總是記不了幾個 keybindings。而 ErgoEmacs 這個專案主要就是在改變 keybindings,讓 Emacs 更能符合現代使用電腦的習慣。這個套件可以從這裡下載。

I totally agree with the remap caps-lock solution, that helps quite a
bit. To go even further, I tried and liked the Ergoemacs
keybindings. The project is being actively developed, and supported
quite well. I personally don't use it because it's not integrated with
Mac OS X (some EMACS Keys are integrated in Cocoa), though it seems
someone has posted an inputrc file with Ergoemacs keybindings. Another
trick I've been playing with is enabling StickyKeys. It's supported on
many platforms and alleviates some of the problems specific to
chording (as opposed to just overuse): it is apparently recommended on
the emacswiki: http://www.emacswiki.org/emacs/StickyModifiers

Subject: Re: ergonomic keybinding. Need qwerty testers.
Some comments:
I've been giving your keyboard mapping a try and generally like it. In
particular, I like the cut/paste series (M-x, M-c, M-v) and the
window-splitting series (M-0, M-1, M-2). I do regret, however, that
the M-c binding does conflict with the default capitalize-word
binding, as I use the capitalization functions bound by default to
M-c, M-u, and M-l pretty frequently. At the moment, I've configured a
"windows" key to be Hyper and bound the capitalization functions to
H-c, H-u, and H-l, so I'll see how that works out.
(I've noticed a slight anomaly - since M-x is bound to kill-region,
M-a is used for execute-extended-command, but when one hits M-a, one
is still presented with a prompt "M-x ".)
As far as the cursor movement bindings, the single character movement
bindings seem natural enough, but I suspect I'll prefer to continue to
use arrow keys. I'll have to give the other movement bindings more of
trial before making a final judgement, though the combinations
involving M+S (Alt+Shift) seem a little awkward to me.
I've bound M-g to goto-line for some time now, and am happy with the
standard C-k for kill-line, so prefer not to rebind M-g.
Similarly, I've bound M-p to ps-print-buffer, and since I don't use
the recenter function too often, am happy to stick with C-l for it.
I found the binding of M-d to delete-backward-char somewhat
disconcerting, because even though I've bound C-delete to kill-word,
I'm still acustomed to having M-d perform the same function in other
contexts (⁖, in Bash).

I have used your ergonomic_keybinding_querty.el a bit. It is
interesting, it looks like it is the right way to go. Solution is
elegant and does not interfere with or disable common shortcuts. There
are two small issues I encountered: The first is that if CUA is
enabled in emacs 22 moving around with page up/down (M-Shift-i and M-
Shift-k) sets mark and starts selecting a region. The other issue is
that on Windows pressing righ-alt + right-shift sometimes changes
Windows keyboard layout.
The main issue for me still remains position of Control keys, but this
needs to be addressed by a keyboard manufacturer.
Thanks,

Pretty impressive.
Do you have the frequency of the C-x prefix ? I use it pretty often,
just wondering what's his rating. I definitively want to try your
layout. Two remarks though. C-h = delete-backward-char is mandatory
for me.
Too many applications use it that way. And the h key is a perfect spot
on the Dvorak keyboard.
Also, C-t, M-t and M-c on a Dvorak keyboard definitely deserve better
shortcuts than the default ones.
I am currently using C-t as the C-x prefix and M-t as M-x.

That's nice, but the best thing about that website is the ‘ergonomic

comfortable.
I know that for long-time emacs users a new layout is perhaps not
something attractive, but for me, being new to emacs, a more modern
and ergonomic layout is just what I needed to get up to speed.
They even have a Dvorak version. Great resource, thanks, I had been

:PROPERTIES:
:PAGE: banish-key-chords.html
:TEMPLATE: blog_static_no_title.html
:END:
This is an experimental ergoemacs feature to banish key chord and
replace ergoemacs keys. The background is given in the following pages
- Why it would be good to [[http://xahlee.info/kbd/banish_key_chords.html][banish key chords]].
- Xah's quest to [[http://ergoemacs.org/emacs/emacs_keybinding_redesign_2.html][totally redesign the keys]].
*** Changing Ctrl+x and Ctrl+c
For emacs, the most common key sequences start with C-x or C-c. This
usually requires the use of the control key, and leads to the dreaded
[[http://ergoemacs.org/emacs/emacs_pinky.html][emacs pinky]]. It also conflicts with the standard Cut and Copy
commands (see [[file:standard-shortcuts.html][standard shortcuts]]).
I've thought about how to take out the use of the
control key and reduce the key chord reduction. This is how
I came up with the Ctrl+c and Ctrl+x replacements:
- Ctrl-x commands can be accessed by QWERTY
@@html:@@Menu@@html: @@ @@html:@@d@@html: @@
- This is *not* the same as the traditional Ctrl+x. Heres how its
different:
- By default all @@html:@@Ctrl@@html: @@ commands are translated to @@html:@@Alt@@html: @@ commands.
- Ctrl+x Ctrl+b could be accessed by @@html:@@Menu@@html: @@ @@html:@@d@@html: @@ @@html:@@Alt@@html: @@+@@html:@@b@@html: @@ (list-buffers)
- C-x b could be accessed by @@html:@@Menu@@html: @@ @@html:@@d@@html: @@ @@html:@@b@@html: @@ (switch-to-buffer)
- Pressing @@html:@@Menu@@html: @@ will
change the type of key translation used. The default for Ctrl+x is
translate/swap the Alt and Ctl keys. Pressing Menu again will:
- Make the keyboard translation for C-x "unchorded"
- The pressing Menu would remove the keyboard translation for Ctrl+x.
- Finally pressing Menu again would result the translation/swap
of Ctrl and Alt (as at the beginning).
For your information, an "unchorded" filter/translation would translate:
- Ctrl key combinations to standard keys. For example Ctrl+b would be
just b.
- Standard keys like b would be translated to Alt+b.
- Alt key combinations would be translated to Ctrl key combinations.
Therefore Alt+b would be translated to Ctrl+b.
- C-c commands can be accessed by QWERTY
@@html:@@Menu@@html: @@ @@html:@@f@@html: @@
- This is *not* the same as the traditional Ctrl+c. Heres how its
different:
- By default the "unchorded" filter is on. This is because by [[http://www.gnu.org/software/emacs/manual/html_node/elisp/Key-Binding-Conventions.html][convention]],
major modes bind control keys like Ctrl+c Ctrl+r and leave keys like
Ctrl+c r to be bound by the user. This means that you would put
less strain on your hand to have these key combinations to be
unchorded by default.
- @@html:@@Ctrl@@html: @@ commands are translated to @@html:@@Alt@@html: @@ commands.
- Like C-x, pressing Menu changes the filter
- First Menu press changes the unchorded filter to the ctl <->
alt filter
- Second Menu press removes the filter
- Press Menu again to go back to the unchorded keyboard filter.*

repeatable. Therefore [Menu] [k] [k] [k] would move the cursor down
two lines. If this is followed by [i] this would have the cursor
move up a line. To exit the repeatable movement/delete keys press
[Menu]. This is similar to VIM's edit mode, with a toggle of the
[Menu] key.
- Shifted keys still are allowed. For example, page up can be
accomplished in QWERTY by [Shift+i].
- Any command that enters the minibuffer also exits the repeatable
movement/deletion.
- Any undefined key in the keymap (like 1) would exit the mode and
insert the character
- To reduce the shifted key-chords, on QWERTY you can also press
[Menu] [i]. Therefore [Menu] [i] [i] is equivalent to one page
up. Followed by a [k] will be the page-down equivalent
- Again, [Menu] stops the movement mode and anything that enters
the minibuffer removes the movement mode.
- Any undefined key in the keymap (like 1) would exit the mode and
insert the character
- Shift and the key is the unshifted command. Therefore [Menu] [i]
[i] [Shift+k] would be Page Up followed by down one character.
***** Method #2 -- Modal Ergoemacs-mode
You can press [F6] to get all the [Alt+] commands bound letters
themselves. For example [Alt+k] is bound to [k]. [Alt+Shift+] keys
are bound to [Shift+] or [Alt+] keys. Hence, [Shift+Alt+m] is bound
to both [Shift+m] and [Alt+m]. To exit ergoemacs modal mode, you
can press [Return] or [F6].

*** Whats the difference between ergoemacs and ergoemacs-mode?
[[http://ergoemacs.org/][Ergoemacs]] is a set of customizations that make emacs easier to use.
It also includes [[file:index.html][ergoemacs-mode]]. The minor mode, [[file:index.html][ergoemacs-mode]],
implements the keybindings (and some other features) via a minor-mode
that can be toggled to get back to standard emacs.
*** How do you select text when using ergoemacs-mode and ergoemacs-arrow keys
You can hold the left @@html:@@Alt@@html: @@,
then right hand press space to mark, then right hand using any of
QWERTY
@@html:@@i@@html: @@
@@html:@@j@@html: @@
@@html:@@k@@html: @@

@@html:@@u@@html: @@
@@html:@@o@@html: @@ to move

Of course, you can also use the [[file:standard-shortcuts.html][standard shortcuts]]. For example,
to select all, you can press Ctrl+a. To move up, you can press ⇧
Shift+↓ to select text downward.
Another option is to use the ergoemacs reduction key theme. Then the
shift-movement keys work.
*** Some of my backspace keys have been muted by ergoemacs-mode
Ergoemacs-mode allows key sequences to be changed with a backspace
key. This masks some of the delete key sequences like C-x Backspace which
runs backward-kill-sentence. You can turn this off by the following
#+BEGIN_SRC emacs-lisp
(define-key ergoemacs-normal-translation-local-map (kbd "DEL") nil)
#+END_SRC
If you wish to remove it from the other specialized translations you can do that as well:
#+BEGIN_SRC emacs-lisp
(define-key ergoemacs-ctl-to-alt-translation-local-map (kbd "DEL") nil)
(define-key ergoemacs-unchordedl-translation-local-map (kbd "DEL") nil)
#+END_SRC
You can also allow ergoemacs-mode to translate the Delete key to
backspace, so Ctl+x backspace can be typed as Ctrl+x Delete key
*** How do you get a 【▤ Menu】 key in Mac OS X
Some of ergoemacs keys make use of the 【▤ Menu】 key.
One way to set this up in a mac is to replace the Caps Lock key with
F13 or above, and tell emacs that F13 is actually the menu key. This
is done by:
1. Downloading and installing [[https://pqrs.org/macosx/keyremap4macbook/pckeyboardhack.html][PCKeyboardHack]]
2. Going to the system prefences and PCKeyboardHack
3. Change the caps lock mapping to F13
4. Adding the translation to emacs startup script (like ~/.emacs or
~/.emacs.d/init.el) as follows:
#+BEGIN_SRC emacs-lisp
(define-key key-translation-map (kbd "") (kbd ""))
#+END_SRC
*** Why don't you use the standard emacs key notation?
The [[http://www.emacswiki.org/emacs/EmacsKeyNotation][emacs key notation]] is common across emacs, but not common for new
users. One of the goals of ergoemacs-mode is to allow new emacs users
to not have to learn anything about the keys to start using emacs.
Therefore, all keys are defined in Ctrl+s notation instead of =C-s=
notation.
*** I was expecting C-j to be mapped to copy but instead it's C-c on my dvorak
You have some options to get to copy and paste:
- You can Alt + the normal key positions for undo cut copy paste
- If you want, you can easily do it with:
#+BEGIN_SRC emacs-lisp
(global-set-key (kbd "") 'ergoemacs-cut-line-or-region)
#+END_SRC
- If you want you can keep /all/ standard shortcuts in the normal
QWERTY positions by:
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-theme nil)
(setq ergoemacs-change-fixed-layout-to-variable-layout t)
(setq ergoemacs-keyboard-layout "dv")
(require 'ergoemacs-mode)
(ergoemacs-mode 1)
#+END_SRC
*** I want to modify my modifiers to work differently on a mac
Ergoemacs-mode uses the option as an alt key because you can press it
with a thumb. If you want a different option, set:
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-use-mac-command-as-meta nil)
#+END_SRC
* Tips
** Gradual Adoption
:PROPERTIES:
:PAGE: gradual-adoption.html
:TEMPLATE: blog_static_no_title.html
:END:
If you are a long time emacs user, you may find it painful to adopt
this setup.
This difficulty is nothing special. It's the same difficulty when you
switching to dvorak after years of qwerty. Basically, it's about
changing muscle memory.
Here are some key-themes that may help you adopt
ergoemacs-mode:
**** Level 1
If you find it too painful to switch, don't use the whole
package. Instead, start off with just the arrow key movements.
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-theme "lvl1")
(ergoemacs-mode 1)
#+END_SRC
Either put the above in your emacs init file (usually at =~/.emacs= or
=~/.emacs.d/init.el=), or customize ergoemacs-mode to set the theme to
lvl1.
With only the above change, you will increase your emacs productivity,
especially if you are a touch typist. These single char cursor moving
commands are the top 4 most frequently used emacs commands by
statistics, roughly accounting for 43% of commands that have a
shortcut.
Once you used the above for a couple of weeks, you may add more keys
to adopt.
file:ergoemacs-extras/lvl1/ergoemacs-layout-us.png
**** Level 2
Adding keys for moving around words and deleting words.
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-theme "lvl2")
(ergoemacs-mode 1)
#+END_SRC
file:ergoemacs-extras/lvl2/ergoemacs-layout-us.png
**** Level 3
Full ergoemacs keyset without the / unchorded keys.
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-theme nil)
(ergoemacs-theme-option-off '(apps apps-apps apps-punctuation apps-swap))
(ergoemacs-mode 1)
#+END_SRC
file:ergoemacs-extras/lvl3/ergoemacs-layout-us.png
**** Full Ergoemacs Keys
Try to use the full ergoemacs mode.
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-theme nil)
(ergoemacs-mode 1)
#+END_SRC
file:ergoemacs-extras/ergo-layouts/ergoemacs-layout-us.png
**** Guru
The guru theme takes away the arrow keys and page up/page down keys.
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-theme nil)
(ergoemacs-theme-option-on '(guru))
(ergoemacs-mode 1)
#+END_SRC
**** Hardcore
The hardcore theme takes away the backspace key as well as the arrow
and page up/down keys.
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-theme nil)
(ergoemacs-theme-option-on '(guru no-backspace))
(ergoemacs-mode 1)
#+END_SRC
** System Wide Keys
:PROPERTIES:
:PAGE: system-wide.html
:TEMPLATE: blog_static_no_title.html
:END:
*** Bash
You can [[http://www.gnu.org/software/bash/manual/html_node/Readline-Init-File-Syntax.html][make bash understand]] ergoemacs-mode keys by creating an
appropriate =.inputrc= and placing it in your home-directory.
When ergoemacs-mode is enabled, this can be done easily by typing
Alt+a =ergoemacs-bash=
This should also be available in the ergoemacs menu.
*** Windows
In windows some of the ergoemacs keys are implemented system wide by
assuming apps follow the CUA-style keys like CTRL-f for find, CTRL-h
for replace. This also optionally implements:
- CapsLock as Menu in emacs
*** Mac OS X
** Customizing your keys
:PROPERTIES:
:PAGE: customize-keys.html
:TEMPLATE: blog_static_no_title.html
:END:
You may want to customize your ergoemacs-mode bindings to fit your
particular workflow. This can be accomplished in many ways,
*** Ergoemacs defined keys
These keys are defined in the =ergoemacs-keymap=. When the layout
changes by changing options, these keys are lost. However, you may
create your own theme to allow these keys to be saved.
**** Adding a ergonomic key
Ergonomic keys can be added by:
#+BEGIN_SRC emacs-lisp
(ergoemacs-key "M-a" 'execute-extended-command "Execute")
#+END_SRC
This adds the Alt-a command to all keyboards based on the QWERTY
layout. This only applies to the currently selected keyboard theme.
Note the last parameter is optional and allows Ergoemacs to document
that this is an "Execute" command when generating keyboard layout diagrams.
**** Adding a fixed key
Fixed keys can be added by:
#+BEGIN_SRC emacs-lisp
(ergoemacs-fixed-key "C-o" 'ido-find-file "Open File")
#+END_SRC
This adds the fixed key to the currently selected emacs theme
Note the last parameter is optional and allows Ergoemacs to document
that this is an "Open" command when generating keyboard layout diagrams.
**** Adding an ergonomic key map with fixed mappings
When you want to add an ergonomic keymap with fixed mappings such as
the ergoprog theme you can add them as follows:
#+BEGIN_SRC emacs-lisp
(ergoemacs-key "M-m s" 'save-buffer "" t)
#+END_SRC
This converts the QWERTY M-m keybinding and the fixed keybinding s to
save buffer
*** Using standard emacs functions
**** Defining keys globally
Ergoemacs respects emacs globally defined keys. To define a global
key, you can use:
#+BEGIN_SRC emacs-lisp
(global-set-key (kbd "M-a") 'backward-char)
(global-set-key (kbd "C-a") 'backward-char)
#+END_SRC
This uses [[http://www.emacswiki.org/emacs/EmacsKeyNotation][emacs key notation]]. In short =M-a= represents Alt+a, =C-a=
represents Ctl+a. For these two examples the key is bound to emacs function
=backward-char=.
When you define a global key that conflicts with ergoemacs-mode
keybindings (after loading ergoemacs-mode) the binding will no longer
active in ergoemacs-mode. Therefore, the binding should be active in
most places in emacs.
There is still a possibility that another major or minor mode will
bind the key. If that occurs, you can locally override the bindings.
Assuming this occurs in =silly-mode=, you can usually override the
settings by setting the keys locally in the major-mode:
#+BEGIN_SRC emacs-lisp
(add-hook 'silly-mode-hook
(lambda()
(local-set-key (kbd "C-a") 'backward-char)))
#+END_SRC
Also note that the order that you define the global-keys matter when
using =ergoemacs-mode=. For example, if you decide to change the
global binding before =ergoemacs-mode= loads, the key definition is
typically ignored when =ergoemacs-mode= is enabled. For example:
#+BEGIN_SRC emacs-lisp
(global-set-key (kbd "M-a") 'backward-char)
(require 'ergoemacs-mode)
(ergoemacs-mode 1)
#+END_SRC
The keyboard definition for =backward-char= is ignored when
=ergoemacs-mode= is enabled. However, if you use:
#+BEGIN_SRC emacs-lisp
(require 'ergoemacs-mode)
(global-set-key (kbd "M-a") 'backward-char)
(ergoemacs-mode 1)
#+END_SRC
then ergoemacs-mode will respect the Alt+a backward character
assignment.
This behavior allows ergoemacs keybindings to override the keys in an
emacs configuration like prelude, emacs-live, etc. If you do not like
this behavior, you can turn it off by:
#+BEGIN_SRC emacs-lisp
(global-set-key (kbd "M-a") 'backward-char)
(setq ergoemacs-ignore-prev-global nil) ; Will not ignore any globally
; defined keybinding
(require 'ergoemacs-mode)
(ergoemacs-mode 1)
#+END_SRC
In this example Alt+a will be bound to =backward-char= for
ergoemacs-mode as well as globally.
If you are loading =ergoemacs-mode= before loading one of these emacs
settings and you want to /ignore/ the keybindings of the settings,
you can also ignore them by using the following code
#+BEGIN_SRC emacs-lisp
(global-set-key (kbd "M-a") 'backward-char)
(require 'ergoemacs-mode)
(ergoemacs-mode 1)
;; Load starter kit here
;; Ignore starter-kit keys in ergoemacs-mode
(ergoemacs-ignore-prev-global) ; Globally defined keys defined
; before this point are ignored
#+END_SRC
One of the disadvantages of using globally defined keys it they will
be bound globally even if =ergoemacs-mode= is not active.
Additionally, they are not Layout independent. For example, defining
Alt+j on QWERTY will not change to Alt+n for colemak.
** Making Keys Easier to type
:PROPERTIES:
:PAGE: aliases.html
:TEMPLATE: blog_static_no_title.html
:END:
Emacs commands are very long and descriptive. It may be a good idea
to shorten commands you use frequently. This can be done by defining
[[http://ergoemacs.org/emacs/emacs_alias.html][aliases]].
Ergoemacs-mode already adds support for a few commonly used commands
like allowing =eb= be the same as =eval-buffer=. These are defined
in the variable =ergoemacs-aliaeses= which may be customized. This
can also be turned off by setting =ergoemacs-use-aliases= to nil:
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-use-aliases nil)
#+END_SRC
** Smart Commands
:PROPERTIES:
:PAGE: smart-commands.html
:TEMPLATE: blog_static_no_title.html
:END:
*** Beginning of Line
Often you wish to move to the beginning of some part of a line. For
example:
#+BEGIN_SRC emacs-lisp
(progn
(ergoemacs-mode 1)) ; This turns ergoemacs-mode on.|
#+END_SRC
With the cursor =|= at the end of the line, you might want to go to
the beginning of the comment:
#+BEGIN_SRC emacs-lisp
(progn
(ergoemacs-mode 1)) ; |This turns ergoemacs-mode on.
#+END_SRC
That way you can delete and change the commment (With QWERTY 【Alt+g】).
You may even want to go to the end of the code line:
#+BEGIN_SRC emacs-lisp
(progn
(ergoemacs-mode 1))| ; This turns ergoemacs-mode on.
#+END_SRC
That way you can delete the comment entirely (With QWERTY 【Alt+g】).
Often you may want to go back to the first non-whitespace character
of the line like:
#+BEGIN_SRC emacs-lisp
(progn
|(ergoemacs-mode 1)) ; This turns ergoemacs-mode on.
#+END_SRC
Or even the fist actual first character of the line:
#+BEGIN_SRC emacs-lisp
(progn
| (ergoemacs-mode 1)) ; This turns ergoemacs-mode on.
#+END_SRC
Once there it is not too useful to go to the beginning of the line
again. So, you may wish to:
- Goto the last text block (separated by 2 new lines; default, [[http://ergoemacs.org/emacs/emacs_key_combo.html][why?]])
- Issue a page-up command
- Goto the beginning of the buffer
All of these can be accomplished by the smart ergoemacs-mode
=beginning-of-line= function, which is bound to 【Alt+h】.
If you don't want ergoemacs-mode to ignore comments when going to the
beginning or end of the line you can change this behavior by:
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-end-of-comment-line nil)
#+END_SRC
You may want to only go to the beginning of line, instead of the
beginning of the indentation (the first non whitespace character).
This can be changed by
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-back-to-indentation nil)
#+END_SRC
You can change the command that is issued at the beginning of the
line by using one of the following commands.
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-beginning-or-end-of-line-and-what 'block) ; Beginning
; of text block
(setq ergoemacs-beginning-or-end-of-line-and-what 'page) ; Page Up
(setq ergoemacs-beginning-or-end-of-line-and-what 'buffer) ; Beginning
; of Buffer
#+END_SRC
You may worry about smart mode-specific commands such as org-mode's
beginning or end of line. Don't worry ergoemacs-mode will respect
it, and do the right thing. This is because ergoemacs-mode actually
replaces the =move-beginning-line= with whatever the mode defines
=move-beginning-line= to be.
For example set:
#+BEGIN_SRC emacs-lisp
(setq org-special-ctrl-a/e t)
#+END_SRC
And then go to an =org-mode= headline:
#+BEGIN_SRC org
,* TODO Install ergoemacs-mode |
#+END_SRC
By pressing the beginning of line command, you would go to:
#+BEGIN_SRC org
,* TODO |Install ergoemacs-mode
#+END_SRC
As hoped/expected.
*** End of line
The end of line command for ergoemacs is just as smart as beginning
of line. For example if your cursor is =|=, and you are at:
#+BEGIN_SRC emacs-lisp
(progn
| (ergoemacs-mode 1)) ; This turns ergoemacs-mode on.
#+END_SRC
may wish to go to the end of the code block:
#+BEGIN_SRC emacs-lisp
(progn
(ergoemacs-mode 1))| ; This turns ergoemacs-mode on.
#+END_SRC
or the end of the line:
#+BEGIN_SRC emacs-lisp
(progn
(ergoemacs-mode 1)) ; This turns ergoemacs-mode on.|
#+END_SRC
The after that you can:
- Goto the next text-block (default, [[http://ergoemacs.org/emacs/emacs_key_combo.html][why?]])
- Issue a PageDown command
- Goto the end of the buffer.
Currently this command is bound to 【Alt+Shift+h】
You can ignore the comment feature by the following initialization code:
You can change the command that is issued at the end of the
line by using one of the following commands.
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-beginning-or-end-of-line-and-what 'block) ; End
; of text block
(setq ergoemacs-beginning-or-end-of-line-and-what 'page) ; Page Down
(setq ergoemacs-beginning-or-end-of-line-and-what 'buffer) ; End
; of Buffer
#+END_SRC
Note that this command also respects mode specific changes to
end-of-line commands (like in =org-mode=).
*** Beginning or end of buffer
This smart will:
1. Goto the beginning of the buffer
2. If at the beginning of the buffer it will go to the end of the buffer.
If you want to go to the beginning of the buffer only, you can turn it
of by setting =ergoemacs-repeatable-beginning-or-end-of-buffer= to
nil:
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-repeatable-beginning-or-end-of-buffer nil)
#+END_SRC
*** Paste
Ergoemacs can allow a paste command to cycle through the previous
items that were copied.
In this case Ctrl+v:
- Pastes the first item
- Upon repeating, Ctrl+v cycles through previous items pasted.
Note that if you move/type then this pattern repeats itself, you will
paste and then cycle through the items pasted.
If you wish to paste an item twice, you can use Ctrl+Shift+v.
When this is disabled, the Ctrl+v only pastes and
Ctrl+Shift+v cycles through the previous items pasted. This can be
disabled by
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-smart-paste nil)
#+END_SRC
This is enabled by default because it reduces pinky usage.
When installed, ergoemacs' smart paste can also use browse-kill-ring
When calling Ctrl+Shift+v if the last command was not a paste, it
starts browsing the kill ring. The standard ergoemacs-mode keys
apply. Pressing Ctrl+v or Alt+v will cycle forward through the kill
ring. Pressing Ctrl+Shift+v or Ctrl+Alt+v will cycle backward
through the kill ring. To accept the text, press enter.
If you want the second paste to call =browse-kill-ring=, you can
enable this by:
#+BEGIN_SRC emacs-lisp
(setq ergoemacs-smart-paste 'browse-kill-ring)
#+END_SRC
*** Smart punctuation
*** Smart Capitalization
This command is an extension of the [[http://ergoemacs.org/emacs/modernization_upcase-word.html][smart Letter-Case command]]. It
also toggles camelCase words when it detects you are in a variable.
When you are outside of a word, it corrects the last mis-spelled
word.
The camel-case is determined by the major-mode's mode's settings in
=ergoemacs-toggle-camel-case-chars=. In emacs-lisp it is more common
to separate variables with =-= rather than =_=. The default setting
for =emacs-lisp-mode= allows toggling between the various variables.
For exampleVariable emacs-lisp toggles between the following:
- exampleVariable
- ExampleVariable
- example-variable
- example_variable
In =R= it is likely that you separate variables by =.= or =_= so
exampleVariable would be toggled between
- exampleVariable
- ExampleVariable
- example.variable
- example_variable
In some modes, like =org-mode= only the toggle letter case is
active.
Any of these can be customized by customizing the variable
=ergoemacs-toggle-camel-case-chars=.
