Caveats on remapping keys

[Tim Johnson <tim@johnsons-web.com>]

Being new to emacs, I've occasionally gotten a little too fast and
lose with redifining keys.  I'm considering using alt & ctrl with
numeric keys.

Now on xemacs in windows I see the following documentation
on 'digit-argument:
   (locally bound to "0", "1", "2", "3", "4", "5", "6", "7", "8", "9")
   (globally bound to "M-0", "M-1", "M-2", "M-3", "M-4", "M-5", "M-6", 
"M-7", "M-8", "M-9", "M-C-0", "M-C-1", "M-C-2", "M-C-3", "M-C-4", 
"M-C-5", "M-C-6", "M-C-7", "M-C-8", "M-C-9", "C-1", "C-2", "C-3", "C-4", 
"C-5", "C-6", "C-7", "C-8", "C-nil")

When I get my linux box back, I will probably be using GNU emacs, and
if I do remap any of the keys above which are now *globally* bound,
what are the implications?

IOWS this is a HMB4IHM (help me before I hurt myself) question.
Comments, caveats and pointers to discussions on this subject are
invited.
