   If the wheel doesn't scroll, why would you want it to trigger the
event in the first place??? For instance, I have a button on the side of
my mouse that's mapped by the mouse settings to the "middle button". My
mouse doesn't actually have a middle button, because I have a scroll
wheel there instead (although, technically that could be used as a
button as well). However, if I wanted that side button to do something
else, I could just change my mouse settings. I could configure any of my
mouse buttons to do anything from "Undo" to "Explore My Computer". This
is an input device configuration issue, not a browser issue. If I
configure my mouse wheel to be an "Undo" button, it should trigger a
"mousewheel"-type event in the first place.

   That doesn't really make sense. The prefix "mouse" is commonly used
for events involving a pointing device, and the event in question occurs
to the element under the pointer device, so it's clear that the first
half of this event should be "mouse".

   As for "wheel" versus "scroll", I think "scroll" is more
device-independent, but I don't really care enough to argue about it...

   Yeah, it shouldn't be much trouble to have Mozilla use "mousewheel".
There's already a bug for it:

https://bugzilla.mozilla.org/show_bug.cgi?id=111647

   We still need to reconcile the event property names and scale. IE
uses "wheelDelta", while Mozilla uses "detail", plus the values returned
by the two are something like this:

   IEEvent.wheelDelta = MozEvent.detail * -40

   So I guess there are still some technical matters to debate.
