Testing with the W3 page <http://www.w3.org/2002/09/tests/keys-cancel2.html> I noticed that no keyup event was generated when turning caps lock on. But one was generated when turning it off.

I believe this is an issue in an underlying component of OS X, and I'm not aware of any workaround.

In particular, the reported behavior of WebKit seems to indicate we have more bugs in this area:
<blockquote>
I've tested this in Chrome and Safari, both of which fire a keyup event after toggling the caps-lock key.


Actual results:

On the first press of caps-lock the keydown event fires.
On the second press of caps-lock the keydown event fires again.


Expected results:

On the first press of caps-lock the keydown event should fire.
On the second press of caps-lock the keyup event should fire, Not keydown again.
