In general we try to make our key bindings fit with the overall Emacs
style. We also have the following somewhat unusual convention of our
own: when entering a three-key sequence, the final key can be pressed
either with control or unmodified. For example, the
slime-describe-symbol command is bound to C-c C-d d, but
it also works to type C-c C-d C-d. We’re simply binding both key
sequences because some people like to hold control for all three keys
and others don’t, and with the two-key prefix we’re not afraid of
running out of keys.
There is one exception to this rule, just to trip you up. We never bind C-h anywhere in a key sequence, so C-c C-d C-h doesn’t do the same thing as C-c C-d h. This is because Emacs has a built-in default so that typing a prefix followed by C-h will display all bindings starting with that prefix, so C-c C-d C-h will actually list the bindings for all documentation commands. This feature is just a bit too useful to clobber!
“Are you deliberately spiting Emacs’s brilliant online help facilities? The gods will be angry!”
This is a brilliant piece of advice. The Emacs online help facilities are your most immediate, up-to-date and complete resource for keybinding information. They are your friends:
“What does this key do?”
Describes current function bound to <key> for focus buffer.
“Exactly what bindings are available?”
Lists the current key-bindings for the focus buffer.
“Tell me all about this mode”
Shows all the available major mode keys, then the minor mode keys, for the modes of the focus buffer.
“Woah, what key chord did I just do?”
Shows you the literal sequence of keys you’ve pressed in order.
Note: In this documentation the designation C-h is a
canonical key which might actually mean Ctrl-h, or F1, or
whatever you have
help-command bound to in your
.emacs. Here is a common situation:
(global-set-key [f1] 'help-command) (global-set-key "\C-h" 'delete-backward-char)
In this situation everywhere you see C-h in the documentation you would substitute F1.
You can assign or change default key bindings globally using the
global-set-key function in your ~/.emacs file like this:
(global-set-key "\C-c s" 'slime-selector)
which binds C-c s to the function
Alternatively, if you want to assign or change a key binding in just a
particular slime mode, you can use the
in your ~/.emacs file like this:
(define-key slime-repl-mode-map (kbd "C-c ;") 'slime-insert-balanced-comments)
which binds C-c ; to the function
slime-insert-balanced-comments in the REPL buffer.
