rawKeyDown - Cross Platform ???

[Richmond Mathewson]

Does anybody know whether rawKeyDown numbers are the 
same cross-platform?

I am trying to get away from cute little red tick GIFs for my 
EFL pupils to click on to check things and moving to hitting 
either the ENTER or RETURN key.

As I author on Mac OS X but deploy on Ubuntu Linux 
I am a bit scared:

AND, on a more global scale, if rawKeyDown numbers 
are not the same some sort of table of equivalents is called for.

sincerely, Richmond Mathewson
