The problem is that each terminal emulator will do that stuff slightly
differently.  For example, the terminal application in my MacOS X
machine (just the computer that was nearest at the moment :)) seems to
be able to deliver F3 and Alt-F3 (different codes), but not Ctrl-F3 or
Shift-F3.

Beyond that, it's unlikely that all the terminfo entries will have the
right keys, or that you're using exactly the right terminfo.  My MacOS
X terminal claims to be "rxvt", which it certainly isn't (although it
might be *based on* rxvt).

If you're just using the raw Linux console, though, kbd_mode will help
a lot.  If you're in X, you might want to just write a real X
application and save yourself the confusion.

Have fun,
