Aide-mémoire pour GNU Emacs

Cette page est un (non exhaustive & usage personnel) aide-mémoire sur les raccourcis de GNU Emacs. Mais ce serait super si cela pouvait aider quelqu’un d’autre.

Misc

Shortcut	Description
C-x C-f	Open file
C-x C-s	Save the buffer to file
C-x C-w	Write the buffer to new file
C-/	undo (alternative: C-x u)
C-h ?	View help options

Selection

Shortcut	Description
C-Space	Begin selection (set mark)
C-g	Cancel selection
C-x h	mark-whole-buffer, put the whole buffer in selection

Deletion

Shortcut	Description
Backspace	Delete the previous character or selection
C-d	Delete the next character (delete-char)
M-d	Delete current or next word
M-\	Delete spaces and tabs around point (delete-horizontal-space)

Killing and Yanking

Shortcut	Description
C-w	Cut selection
C-k	Kill (or cut ) rest of line or multiple lines (kill-line)
C-S-Backspace	Kill an entire line at once (kill-whole-line)
C-y	Yank (or paste) the last kill into the buffer
M-y	Yank earlier kills, or replace the text just yanked with an earlier kill

Buffers

Shortcut	Description
C-x C-b	List available buffers
C-x b <buffer_name>	Switch to <buffer_name>
C-x k	Kill a buffer
C-x Right Arrow	Move to next buffer
C-x Left Arrow	Move to previous buffer

Multiple windows

Shortcut	Description
C-x 0	delete-window
C-x 1	maximize-buffer
C-x 2	split-window-below
C-x 3	split-window-right
C-x o	Move the cursor to the other window (“o” for “others”).

Search

Shortcut	Description
C-s	Incremental search forward
C-r	Incremental search backward
Alt %	Query replace keywords

Example usage:

Type C-s <keyword> to start a search for <keyword>. Type C-s again to search for the next occurrence of <keyword>. Type <DEL> to go back to an earlier location of the <keyword>. If there are no earlier occurrences, the <DEL> erases the last character in the search string. Type <Return> (or C-g) to terminate the search.

Backward search: use C-r instead of C-s. Everything that we have said about C-s also applies to C-r, except that the direction of the search is reversed.

Type Alt % to do query-replace, then y to confirm the replacement at each occurrence, n to skip, ! to confirm without asking, and C-g to cancel the search.

Multiple cursors

Add private configuration to config.el:

(require 'multiple-cursors)
(global-set-key (kbd "C-S-c C-S-c") 'mc/edit-lines)

(global-set-key (kbd "C-<") 'mc/mark-previous-like-this)
(global-set-key (kbd "C-c C-<") 'mc/mark-all-like-this)
