create new key prefix

create new key prefix

[ken]

I've defined quite a few new keys over the years and so would like to 
create a new key prefix.  I.e., I want to be able to define keys such as 
"C-c p s", "C-c p m", etc.  So how do I tell emacs that (for all 
possible modes) I want "C-c p" to look for the new key definitions.

 From what I've read so far, how this is done depends a lot on the 
particular emacs version.  Mine's 22.1.1.


Thanks

`(global-set-key (kbd "C-c p m") 'func-name)` doesn't work for you?
The caveat to that is that modes down the line can possible shadow the
binding. But that's easy enough to solve with `(eval-after-load…`
forms.

Timmy,

Thanks much for the reply.  I have almost no idea what you said, but it 
got me to try the code which I already wrote (which I didn't do before 
because I didn't think it would work, thought sure there was something 
missing).  The code I already wrote and left sitting there untested for 
a couple-three hours... it works!!

Well that's a completely new experience for me.  B^D

LOL. Good to know.

As an aside, what are you confused about regarding what I said? Maybe
I can help clear some things up for you?

What I read in several docs on the web implied that a command was needed 
first to create a sparse map (i.e., define-prefix-command) and then to 
assign it to a key prefix, in my case, "C-c p".  So when you 
wrote/asked, "`(global-set-key... doesn't work for you?", it didn't 
compute with me at all at first because it seemed like you were 
ignoring/forgetting all that.  But then 1% of me thought, maybe this guy 
is one of the 0.02% who knows what he's talking about, prompting me to 
try running my own code (which was likewise ignoring/forgoing sparse map 
creation etc.).  My crap not only ran without error, but it also worked 
perfectly!

The other part is the reference to "(eval-after-load..."; from your 
context I gather that it's meant to remedy some other code stepping on 
my keybindings (and perhaps too other definitions).  But how, when, and 
where to actually implement that function gribbles the laft whicher 
bonkhaft.

Generally you use sparse maps, etc. when you're defining a keymap for
a mode that you're writing or when you want to activate a group of
keys all at once. In your case you probably aren't intending to do
that.

`eval-after-load` is just a way to evaluate a function after a library
is loaded. In other words, if I wanted to have `C-c p p` do something
but `mode-x` defined `C-c p p` to do something else, the easiest way
I've found to step on the mode's definition is to do an
`(eval-after-load 'mode-x '(local-set-key (kbd "C-c p p")
'func-name))`. That will reset they key in that mode back to what you
want it to be.
