doesnt work on Mac Firefox 4 or 3.6

Another example that shows that it is key events that don't work: http://jsfiddle.net/dydkJ/5/show/

Works if the chars are going into a focusable element, and the behavior is independent of jQuery:

The W3C seems to indicate this is acceptable:

If the key does not cause text input and is not the Escape key (i.e. if the key is not is an alphanumerical key, a punctuation key, a repeated press of a dead key or the Escape key), terminate this algorithm.

http://www.w3.org/2008/webapps/wiki/Legacy_key_events#Processing_of_Keypress_Events

Quirksmode seems to confirm this interpretation:

keypress - Fires when an actual character is being inserted in, for instance, a text input.

Is there some connection here with jQuery?
