Be careful about binding your application directly to specific key
codes.  I'm not a programmer either, but I believe what you are looking
for needs to be interfaced through terminfo/termcap.

Termcap/terminfo are databases of terminal types, and if you build
your application with these ...  now I don't know what the word is ...
includes/libraries (?) ... anyway, have a look at /usr/include/term.h,
termio.h and termios.h (from Solaris 2.5.1, but linux should have 'em too)

Any comments from the peanut gallery?
