Use of 'pause' as key prefix

Use of 'pause' as key prefix

[Kenneth Jacker]

I'm trying to use the 'pause' key as a prefix "character" so that I
can bind functions to key sequences like "pause a", "pause b", etc.

My efforts so far have failed (mainly elisp syntax errors).
I could find no help in 'info' and/or "searching the web" ...

Is this possible?  Suggestions on how to so define?

Thanks,

  -Kenneth

(defvar pause-map nil "Keybindings with Pause as prefix")
(define-prefix-command 'pause-map)

(global-set-key '[(pause)] 'pause-map)
(define-key pause-map '[(t)] '(lambda ()
				(interactive)
				(insert "Testing Pause Prefix")))


Note however, that I'm not really sure whether this is the supposed
way to do it. Maybe someone with deeper understanding of this could
enlighten us?

Wow, thanks Stefan, for the fast reply!

Sorry, but I don't understand how to use the above to define
additional associations using 'pause-map', e.g., "pause a", "pause b",
etc.  Maybe time for me to RTFM?  ;-)

Thanks again,

  -Kenneth

Does

(define-key pause-map '[(a)] '(lambda ()
				(interactive)
				(insert "pause a pressed")))
(define-key pause-map '[(b)] '(lambda ()
				(interactive)
				(insert "pause b pressed")))


help?

I see, the `t' (for "Testing" I assume) is the character following
the "pause"  ...  duh, I feel like an idiot!

Yes, very much.

Sorry I didn't "grok" your original example.

Thanks, Stefan!

The following snippet is from my ~/.emacs file

(defvar PauseMap nil "function keys with prefix [pause]")
(setq   PauseMap (make-keymap))
(define-key global-map [pause] PauseMap)
...
(define-key PauseMap "h" 'highlight-regexp-current-word)
...

OK, more useful example code ...

Thanks to you and all the others who helped!

Re: Use of 'pause' as key prefix

One more question!

I have defined 'pause' as a prefix, and am able to bind to 
"pause pause" with this:

   (define-key pause-map '[pause] 'f0)

How can I bind a function to "pause pause pause"?

Again, I tried various syntax combination, but wasn't able
to do it in a way that worked.

(define-key pause-map '[pause pause] 'f1)

(kbd "<pause> a") == [pause ?a]

  jb> (kbd "<pause> a") == [pause ?a]

Ah, so I'd do something like this?

   (global-set-key  "[pause ?a]" 'f0)
   (global-set-key  "[pause ?b]" 'f1)

No need for a "map"?

Thanks, Johan!
