I don't know who wrote it ... but I do know that pretty much none of  
the gnustep developers have really been X programmers.  Also, even if  
the comment was accurate when it was written, that could have been  
several years ago and X has changed.

I guess monitoring *all* key down and key up events may be the way to  
do it ...
You could override [NSApplication- 
nextEventMatchingMask:untilDate:inMode:dequeue:] and [NSApplication- 
discardEventsMatchingMask:beforeEvent:] to keep track of the numeric  
keys.
I'm no expert on this though ... you may get better advice.
