Looking up and CALLING a key binding

Looking up and CALLING a key binding

[TheLonelyStar]

Hi,

I know very little elisp have basicly no practical expirience with it.

I know I can lookup a keybinding with lookup-key and similiar.
But how do I look it up and call it (execute it)?

Thanks!
nathan

what exactly you want to do?

are you writing a elisp program? ... or you trying to do something in
emacs?

once you know what command the binding is associated with, you can
just call the command by typing Alt+x commandName.

if you are writing elisp... once you get the command name, say it is
forward-word, then you can run it by just (forward-word) ... some
example of your case would be good to clarify.

C-h f call-interactively

If you are trying to find WHERE a command is mapped, C-h w <command-
name> runs where-is and gives you the keystroke-sequence

If you are trying to find the NAME of a command, C-h k <keystroke-
sequence> runs describe-key and gives you the command-name mapped to
the keystroke-sequence.


Once you know the name, then you can execute it via M-x as Xah said.

Hi,

I need this for the following two things:

1. I want to bind a key (the tab key) to a special function which can fail.
If the function fails, I want to call the original  binding of the key
(which is differerent depending on which mode I am in).

2. I want to bind a key to the insertion of a little code snippet.
i.E. { -> to
{
  |
}
But since in many modes the "{" and "}" keys are bound to some special
function, I want to call these keybindings for the insertions of the "{" and
"}".

This is what tabkey2 mode (and its predecessor) tries to do. Please
see EmacsWiki.

You can use a minor mode for this. Minor mode key bindings comes
before major mode.

do it like this:

(funcall (lookup-key (current-global-map) (kbd "M-r")))

this will find out the function assigned to the key “Alt+r”, then call
the function.

It will call the function with no arguments, so if it has required
arguments it will fail.  Use call-interactively instead of funcall
to provide any required arguments.
