This isn't the friendliest test case, but:
http://software.hixie.ch/utilities/js/live-dom-viewer/?%3C%21DOCTYPE%20html%3E%0A%3Cscript%3EsetInterval%28%22w%28document.activeElement.tagName%29%22%2C%20500%29%3B%3C/script%3E%0A%3Cinput%20type%3D%22text%22%3E%0A%3Ctextarea%3E%3C/textarea%3E%0A%3Cdiv%20tabindex%3D%220%22%3Ealpha%20%3Ca%20href%3D%22%23%22%20onclick%3D%22return%20false%3B%22%3Ebeta%3C/a%3E%20gamma%3C/div%3E

Firefox doesn't support document.activeElement or any equivalent, AFAIK.
Konqueror doesn't support document.activeElement or any equivalent, AFAIK.
Opera supports document.activeElement, returns either the explicitly
active element or null
Internet Explorer 6 returns either the explicitly active element or
the body element
I don't have Safari handy

Maybe the body element is better in this case.
