keyboards in javascript

[McIntyre]

I'm working on a website in which it would be useful for an event to happen when a user pressed a specific key (i.e. one of the arrow keys) as oppose to simply "onkeypress" for any key. Is there any way I can get the browser to recognise which key the user has pressed?
Thanks.

Apparently onkeydown will accept a cursor key press, but you're limited to IE.
