Bind C-. in emacs -nw

Bind C-. in emacs -nw

[Thierry Volpiatto]

Hi,
i am unable to bind something to `C-.' in emacs -nw.
It seem the "C" of Control is not read, it print only "." like
self-insert-command.

If i bind `C-l' for example no problem.

So:

(global-set-key (kbd "C-.") 'foo) ==> fail
(global-set-key (kbd "C-;") 'foo) ==> fail
(global-set-key (kbd "C-l") 'foo) ==> OK

Is it a bug or i misunderstand something?

The binding works just fine, I'm sure, as you can check by typing C-x @ c
. (to emulate C-.).  It's the key C-. itself that cannot be typed on a
terminal (and apparently results for you in just the . being sent).

No xterm (version 250) is worst, instead of just printing "." it print:

27;6;46~

I use mostly rxvt-unicode.

I will find another key just for use in (x)terms, that is for anything.
Thanks.

Without .xdefaults setting, it does the same.
It print 27;6;46~, but that is only in minibuffer.
(My anything command is run from minibuffer)

If i set the same key in global map from scratch buffer like:

(global-set-key (kbd "C-.") 'somesimplecommand)

when i hit `C-.'  it print "~" (and don't call the command)" .
Same for `C-:' it print "~".
If i bind `C-,' or `C-;' i have C-, or C-; is not defined.
