Yep, and I'll be watching out for your post.
Believe me, if done correctly, DOM code can greatly increase the
efficiency of your code.
I was just benchmarking some code the other day and in a field of 20,000
elements, traversing the childNodes as opposed to seeking with
getElementById yielded that traversing the DOM was 26.25 times faster.
The same can be said about innerHTML as opposed to creating text nodes.

No it isn't. Sure it is high, but it is nowhere near 99% I am sure.
You forgot Mac users (Camino, Konqueror, iCab et cetera) and Opera users.
And for God's sakes man, give the users something to see when JavaScript
is disabled.

Aaah, there we go. Internet Explorer 6 has a go at it. Now I get
"console is undefined", *sometimes*. It is remarkably slow though.
Now, in Firefox 1.5.0.11 it runs smooth as silk. *EXCEPT*, clicking on
the copy/paste whatever stuff takes quite a few seconds to load.
This also happens in the loading of both Internet Explorer and Firefox,
where it takes a substantial amount of time to load. In actuality I get
a "warning unresponsive script" in Firefox every time and I have to hit
"continue."
Now, you ready for the big kicker? All this time I think I did not hit
a button before traversing with the keys. For the most part I tried to
hit a button, then draw with the cursor. *sigh*
Good job!
