For anyone wanting to test what rawKey codes their keyboard gives, here 
is a utility I wrote ages ago to do this:

While differences between keyboards & operating systems are annoying, 
the keys you are checking are mostly available using other messages. In 
NumLock is on, the numeric keys generate arrowKey messages and if 
NumLock is on, the number can be read directly in a keyDown or keyUp 
handler.
