List of current key maps

List of current key maps

[Will]

Hi!

Is there a way to find all active key maps used in the current buffer 
with their actual variable names so one can use those names to make 
lcoal keybindings like

(define-key ess-mode-map [(control ?c) (control ?t)] "Test!")
             ^^^^^^^^^^^^

Using the variable search function C-h v map [enter] is not helpful as 
it searches only for variables beginning with "map" not containing "map" 
somewhere in its name (opposite to "C-h a"-behavior, is this a bug of 
C-h v???)

Thanks for helping,

Will

Try M-x apropos-variable

and no, the C-h v behavior is correct, not a bug.

http://www.emacswiki.org/cgi-bin/wiki/Icicles

In Icicles:

* `C-h v map S-TAB' completes to variables whose names contains "map".

* `C-h v map TAB' completes to variables whose names start with "map" (just
as in vanilla Emacs).

* You can use `M-*' to match against multiple patterns (e.g. "map",
"mode",...) - as many as you want. So, for example, `C-h v map M-* local M-*
mini' completes to variable names that contain "map", "local", and "mini",
in any order.

* You can use `C-~' (complement) to remove matches. So, for example, `C-h v
map M-* local M-* mini C-~' matches variable names that contain "map" and
"local" but do not contain "mini".

* You can use regexps, not just substrings, as match patterns for `S-TAB'.
So, for example, `C-h v [^-]map' completes to variables whose names contain
"map" following any character except `-'. And `C-h v map.' completes to
variables whose names contain "map" but don't end in "map" (more precisely,
contain "map" followed by a non-newline character).

* The same completion features are available for any kind of completion:
buffer name, file name, command, and so on. So, for example, `C-x C-f map'
completes to files whose names contain "map".

* You can use `C-M-mouse-2' to get help about selected completion candidates
on the fly, before choosing one to use. So, for example, `M-x map S-TAB'
followed by `C-M-mouse-2' on selected completions in buffer *Completions*
prints the descriptions of those clicked commands (whose names contain
"map") - as many as you like, in any order. (Hit `RET' to finally choose one
to execute, or hit `C-g' to cancel.) Or, for example, `C-x f ab TAB'
followed by `C-M-mouse-2' on selected file names (which all begin with "ab")
prints file properties (file type, permissions, size, times, etc.).

Icicles has a lot to offer, and the doc describes it all, but the basic
features are simple to use - you can take advantage of them without reading
any doc. And `C-?' during completion gives you summary help.

Thanks, Tim for the hint. However, it does not deliver the necessary 
"map" variable names, one has to submit a numerical argument like

C-u 1 M-x apropos-variable

or add this line to your .emacs file

(setq-default apropos-do-all 1)

Typically, the keymap is not defined at startup, so you can't do the above
directly: you have to do it in a hook or somesuch.  So a common solution is
to do:

  (add-hook 'ess-mode-hook
            (lambda ()
              (local-set-key [(control ?c) (control ?t)] "Test!")))
