Finding commands and key bindings in GNU/Emacs
Since I use GNU/Emacs for everything, I can't remember all the key
bindings for all the different modes (org-mode, gnus, geiser,
etc.). So I often use the command names using
Sometimes, I don't even remember the exact name of the command and I
will use the TAB completion to see suggestions. But for that, I need
to remember the beginning of the name of the command. If I remember a
part of the name of the command, say, find, typing
followed by TAB will propose all available commands whose name
So far so good.
If I don't know at all the name of the command, there are a couple of
things that I can do. One would be browsing the menus in the menu
bar, but since my menu bar is hidden1 in order to increase
screen real estate, I would need to show it (
and grab the mouse. Instead, pressing
F10, a pop-up menu which can
be keyboard driven appears and I can browse the menus.
I only would do this if I was bored, but this is rarely the case, so
I prefer another possibility. I use
C-h m, which is bound to the
describe-mode command which displays the documentation for all
active modes for the current buffer.
In this documentation there is a table showing all the available key bindings and the corresponding commands. When in an org-mode buffer I get this:
key binding --- ------- C-a org-beginning-of-line C-c Prefix Command C-e org-end-of-line TAB org-cycle C-j org-return-indent C-k org-kill-line RET org-return C-y org-yank ESC Prefix Command | org-force-self-insert ...
Usually, this allows me to find the command I need and recall (at least for 5 minutes) the corresponding key binding.
If I am not sure if a command does what I need, I can always use the
describe-function (bound to
C-h f) command to get its
documentation. If I invoke the command with the cursor on one of the
commands of the table above, this will be used as default command to
be described by
Nice and efficient.
