In Emacs, almost any keystroke, optionally combined with one or more modifier keys, or any sequence of such keystrokes, can be "bound" to any command.
Modifier keys naming convention
| Modifier key | Abbr. | Remarks | Example | Action |
|---|---|---|---|---|
| Alt | A | Relatively seldom used in Emacs, because Meta is often "logically" mapped to the "physical" Alt key. | A-x | Type "x" while holding down the (non-Meta) Alt key |
| Control | C | C-x C-f | While holding down Ctrl, type first "x" then "f". (This runs the command find-file). | |
| Hyper | h | Often not mapped to any key (by default). | h-x | Type "x" while holding down hyper |
| Meta | M | Often mapped to Alt on your keyboard | M-x find-file RET | Either:
(M-x activates the minibuffer) Then type "find-file" in the minibuffer, then Return. |
| Shift | S | S-x | Type "x" while holding down Shift | |
| Super | s | Often not mapped to any key by default, or to Window or Menu if present | s-x | Type "x" while holding down super |
By convention, when multiple modifiers are specified, they go in alphabetical order: [C-M-x] not [M-C-x].
Printable cheat sheet for popular modes
Emacs ships with cheat sheets of common and useful key bindings. The pdf files are located in the refcards/ subdirectory of data-directory.
Change key bindings
You can add, remove and change key bindings for any command.
- M-x global-set-key or M-x local-set-key
- Hit the key sequence you want to bind
- Type the command to bind to that key sequence
- Type {{Command|C-x ESC ESC|repeat-complex-command}. The output you see is the full lisp command which does the binding. You can copy this to your Emacs configuration file.
