In general, it's not a good idea to use other programs when you use Emacs. 
Your operating system should be a bootloader for Emacs. ;-)

Joking aside:

That depends on your preferences.  Either you want/can change the bindings 
used by other programs, or you change the bindings used by Emacs.

If the choose the former, the problem is that Emacs puts commands on 
almost all keys.  You can however safely use the function keys: F5 to F9 
will by convention never be predefined by Emacs, the commands on F1 to F4 
are available elsewhere, and F9 and F12 are AFAIK not used by Emacs.  F10 
and F11 are used by Emacs however, and their commands are not available 
elsewhere by default.

If you choose the latter, you have the same problem: you have to move the 
commands to some free key, and there aren't many, especially if you want 
to use the same bindings in a terminal.  But you can also safely use the 
functions keys, and the C-c LETTER bindings, which are by convention 
reserved for users.
