Another thing I noticed:

With the attached, 'keyup' doesn't fire if you use an alert() in the  
'keydown' or 'keypress' handler.

Well, actually, it fires sometimes in Firefox and Safari, but it's not  
very consistent. Avoiding alert()s makes things more consistent.

I also noticed that with the attached in Opera, if you press the spacebar  
in the field, the alert that pops up disappears right away because the  
space somehow gets invoked on the OK button on the alert().
