How to change keys for uncomment (C-u C-c C-c)?

[JS]

When I want to uncomment someting I first need to press C-u followed by C-c
C-c but that is not very handy. Is it possible to reconfigure C-u C-c C-c
into ie.:

C-c C-c C-v instead?

Which major mode are you talking about?  For me M-; works fine in
all major modes i use.  See C-h k M-;

hm nothing happens if I select some code and press M-. The selected area
disappears and in the tiny buffer in the buttom there is only this text:

any idea?

Ok I have this in my code:

/*   if (f != NULL){ */

When I select that line with the mouse and press:

M-; (Holding down my Alt key and ";")

I get this error:

No M-x tags-search or M-x tags-query-replace in progress

Hmm... What says C-h k M-; ?

I have just tried C-h k M-; and it gives me:


M-, runs the command tags-loop-continue
   which is an interactive compiled Lisp function in `etags'.
(tags-loop-continue &optional FIRST-TIME)

Continue last M-x tags-search or M-x tags-query-replace command.
Used noninteractively with non-nil argument to begin such a command (the
argument is passed to `next-file', which see).

Two variables control the processing we do on each file: the value of
`tags-loop-scan' is a form to be executed on each file to see if it is
interesting (it returns non-nil if so) and `tags-loop-operate' is a form to
evaluate to operate on an interesting file.  If the latter evaluates to
nil, we exit; otherwise we scan the next file.

--------------------
On my keyboard I get ";" by pressing Shift-,

If I try to press M-shift-,  nothing happens.

So I guess the problem is that I can only get ";" if I press Shift at the
same time.

And with C-h k before "M-shift-," (Holding down Alt *and* shift
and then ",")?

Anyway, that's probably not a convenient key binding. You may as
well try:

        (global-set-key "\M-," 'comment-region)

or get an US Keyboard ;)

I have just entered this in my .emacs fil:

(global-set-key "\M-," 'comment-dwim)

When I start up emacs I get this error:




An error has occurred while loading `/home/johs/.emacs':

of the error in your initialization file and remove it.  Start
Emacs with the `--debug-init' option to view a complete error

I have then tried to start emacs like this: emacs --debug-init and then I
get this:

Seems like your newreader put some extra magic characters in the
parent post. Try this:

 (global-set-key "\M-," 'comment-dwim)

When I do C-h k followed by "M-shift-," I get this:


M-; runs the command comment-dwim
   which is an interactive compiled Lisp function in `newcomment'.
(comment-dwim ARG)

Call the comment command you want (Do What I Mean).
If the region is active and `transient-mark-mode' is on, call
  `comment-region' (unless it only consists of comments, in which
  case it calls `uncomment-region').
Else, if the current line is empty, insert a comment and indent it.
Else if a prefix ARG is specified, call `comment-kill'.
Else, call `comment-indent'.


So I guess it should work. I have some commented text that I select with the
mouse. The I press "M-Shift-," but nothing happens.

I have then changed the value for transistent-mark-mode to "on" and now it
seems to work, but now everything gets painted in yellow when I use
-space...but I guess it ok.

All things are possible.  But `C-c C-c C-v' is not necessarily a good
choice, because its prefix key `C-c C-c' is already bound to
comment-region (as you know) and all `C-c C-LETTER' keys are reserved
for major modes.  But since all of the `C-c LETTER' keys are reserved
for users, how about `C-c c' or `C-c u':

(add-hook 'this-major-mode-hook         ; e.g. 'c-mode-common-hook
	  (lambda ()
	    (local-set-key "\C-cc" 'uncomment-region))) ; or "\C-cu"

I just wrote this in my .emacs file:


(add-hook 'this-major-mode-hook
          (lambda ()
            (local-set-key "\C-cc" 'uncomment-region)))




But when I restart emacs the program is split in two and I get this error:



An error has occurred while loading `/home/johs/.emacs':

Symbol's value as variable is void:

'this-major-mode-hook is supposed to be replace by the name of the
mode hook whose mode you actually want the key defined within.

Perhaps if you just use this.

(global-set-key "\C-cc" 'uncomment-region)

And move to something more complicated (such as the prior suggestion)
if this causes you problems.

That form would not (in fact, cannot) cause that error.  Either you
mistyped it or there is another error in your .emacs file.

So why don't you try that?  It will bring up a *Backtrace* buffer
showing the stack of function calls that led to the error.

I don't know about you other guys, but something seems fishy with JS'
.emacs file. When I read the post above, each supposed-to-be space
character has a magenta coloured backlshash in front of it, suggestion
some special or control-character.

I won't paste his text here again (it is above), but if you do not see
what I see, this is how it looks (drawn in normal ascii):

  (add-hook 'this-major-mode-hook
  \ \ \ \ \ \ \ \ \ \ (lambda\ ()
  \ \ \ \ \ \ \ \ \ \ \ \ (local-set-key\ "\C-cc"\ 'uncomment-region)))

When I put the cursor on one of those and used C-x =, this is what I
got:

Char: \  (04240, 2208, 0x8a0, file 0xA0) point=961 of 1442 (67%) column 0 

Note: I had to use normal ascii to be sure that the "backslash-space"
char above was displayed correctly. It is indeed only one character.

Anyway, just a thought.

iso-8995-1 0xA0 is "non-break space".  Perhaps JS's newsreader (Knode) is
"trying to be helpful" in pre-empting the possibility of the line being
broken up by filling.
