C-j is not doing as it is being told

C-j is not doing as it is being told

Hi
 
I wanted to remap some key combinations, including C-j. I use
global-unset-key followed by global-set-key for each key combo and it
works fine most of the time apart from when emacs enters Latex-mode
where C-j reverts to its default behavoir and ignores my remapping.
Any suggestion what is causing this and what I can do to stop it?
 
Cheers,
kjitta

Latex-mode has a local key binding.  Global bindings are defaults that 
local bindings can override.

You might win friends by posting in plain text format.  The MIME stuff
made your post ~5 times bigger, without adding any content.

Latex Mode binds C-j in its local keymap.  Anything in a local keymap
will override global bindings.

First of all, are you _sure_ you want to change this binding?  I don't
use Latex Mode, but looking in its manual (C-h C-k C-j) find that C-j is
bound to `tex-terminate-paragraph', which does useful things like
checking for unbalanced braces, and so on.

Assuming you really are sure, the thing to do is to remove C-j from the
Latex Mode keymap.  Try this in your .emacs (untested):

(eval-after-load "tex-mode"
  '(define-key tex-mode-map "\C-j" nil))

(like "aa"), remove half of them (leaving, say, "a").

I was being frustrated by a similar problem until I looked at the 
documentation for global-set-key. It mentions that "if KEY has a local 
binding in the current buffer, that local binding will continue to 
shadow any global binding that you make with this function." So I tried 
inserting a call to local-set-key in the hook of the appropriate mode. 
I can't say whether this is the "right" way to go about it, but it 
seems to work.
