keyCode always return 0. which returns the correct value. But shouldn't keyCode
return the same as which? 

Reproducible: Always
Steps to Reproduce:
1. run testcase

Attachment: run this and press any key

One other bad thing, is that when you press the button the document has not the
focus, the urlbar has it.
After clicking on the document it works. But then you notice that if you press
the spacebar the alert button shows for a milisecond and then it disappears!

When trying the testcase, not every key results in keyCode 0.
For example, RETURN causes 13, and ESCAPE 27.

Yes, also the arrow keys return a value, but not all the keyboard. About
pressing space and the disappearing alert, maybe I should file a new bug on that?

Event.which is an old property from Netscape 4.x.  Mozilla uses event.keyCode
and event.charCode.  These values are set differently depending on the event
although the general rule is that keypresses which generate characters use
charCode and keypresses which do not use keyCode.  Event.which is set to
whichever value most closely matches the old values returned by 4.x and is not
expected to match keyCode or charCode 100% of the time.

Attachment: Demonstrates Firefox mishandling keyCode, all other browsers work correctly.

I see no reason why this bug was abandoned in 2001, I've just come across this issue and as far as I can tell the keydown event has not been deprecated (unable to find any reference to a list of events in DOM4).
