Actually, this is half right...
The function keys all share the same charCode, but the six keys above the
arrows all have their own "magic" charCodes.  They were chosen to make sense
in the ASCII realm of things (delete is $7F).  I'm actually surprised to
see that it is not documented in Inside Macintosh, but the codes can be
determined empirically (they won't change).  Of course, some of these
charCodes can also be generated with the control key pressed, so using the
virtual key codes might not be so bad after all.
