/*

Detecting keys in browsers throws up lots of quirks. For example, Safari refuses to propogate
some events (like 'esc') if you're focussed in a text box. See http://unixpapa.com/js/key.html
for a decent, if depressing, overview.

Basically though, I think I've worked out a way to cross-browser detect any key-stroke.
Once you start typing in a text box it all changes again though, which is really annoying,
but you can deal with it by using a keydown and keypress handler to look for separate things.
Rule of thumb: use keypress to detect characters, use keydown to detect special keys.
