Adding a keybinding for a major mode

Adding a keybinding for a major mode

How come the short cuts for M-x comment region (C-c C-c) and M-x (C-u C-c C-c) uncomment-region only work in some major modes an not others (for example emacs-lisp mode)? And how would I enable them for certain modes?

Maybe because they break the conventions?

 (info "(elisp) Key Binding Conventions")

BTW, if you want to find out where the keys are bound this way then you
might use the command `describe-key-and-map-briefly'. Ehum, which comes
with nXhtml (just because I do not have time to distribute it another way).

maybe because comment-region and uncomment-region are probably
replaced by comment-dwim (Ctrl+;).

emacs lisp mode is a old, basic mode... i doubt it breaks emacs
keybinding conventions.

You are right, I should learn to read a bit better before I answer:

C-c C-c is reserved for major modes ...
