efficient editing question (hot key , ccmode)

[Ronald]

If I press ``M-(", there will be a space before `(' ,
how to inhibit it?
And how to let ``{}" work in the same way?

When the caret is in the middle of a line,
how to new a line and move the caret there automatically?

(setq parens-require-spaces nil)	;no space before parens with M-(

> And how to let ``{}" work in the same way?

Unfortunately it is not working out of the box analogous because M-{
is already taken by forward-paragraph.  Or is there some hack in
cc-mode, please let me know.

At least I got M-" running without interfering something:

(global-set-key [?\M-\"] 'insert-pair) 	;insert pair of quotes (`"'), see lisp.el

what do you mean exactly by caret? (Sorry, not a native speaker
myself.)

Found that AUC-TeX has C-c { for inserting a pair of braces.  Maybe
it's the same with cc-mode?

If by caret you mean point: C-e RET

Maybe I should get the function,``insert-pair",first.

Maybe I should define something like C-; , who has less key strokes.

It's a standard Emacs (22) function.

When it's not taken already, why not?

Oops, sorry for not checking that.
