I ran into something interesting when reading the svg spec and ended up
doing some testing.
I ran into the "onactivate" event. "activate" is essentially the way <a>
tags work. In other words the event fires on a onclick and also when
onkeypress is fired for the enter key on an element.
Looking a bit up on Wikipedia's list of dom events there are 3 variants
listed: activate DOMActivate and command.
Command isn't supported by any browser that I know of. However Firefox,
Konqueror, and Safari all support DOMActivate, and IE7 supports "activate".
Opera does not appear to support any of them.
So it appears to be supported natively by gecko, webkit, khtml, and
trident. So 4/5 of the major engines, presto being the last. And it can
be emulated mostly in other browsers by binding a click and onkeypress
event and testing for the Enter key in the keypress event.
I think the activate event would be a good thing to support in the next
version of jQuery with a bit of cross-compatibility in jQuery.event and
a $().activate helper.
It's something few bother to do in every app they develop, and as a
result when overriding links in webapps and doing event delegated things
most developers just stick with onclick events and don't bother to
replicate the actual range of interactivity with links which is click,
enter, and accesskey.
