Trapping Command-q

Sarah's commandKeyDown trap doesn't seem to work, which is why I'm  
puzzled.  Marty: Ken's method would work to prevent the user from  
quitting Rev, but I was hoping to find a more general method that I  
might use to trap various Apple events such as Command-P and Command- 
W.  Again - I'm sure that I used a solution like Sarah's once upon a  
time, but it doesn't seem to work now.  Obviously this wasn't an  
issue at all in MetaCard...

Cheers,
Jason
