See http://unixpapa.com/js/key.html and http://www.slideshare.net/pp.koch/yahoo-1337458 for researches on the subject. Basically, and practically, use keyCode in keyDown and keyUp events, and charCode in keyDown events (except in Opera, where keyCode can be used as a fallback). I can't tell how this would translate to spec text though. -- Thomas Broyer /tɔ.ma.bʁwa.je/
