My understanding is that they're trying to spec this in a way that doesn't make existing mousewheel code written for IE incompatible. Here's a quote from the |onmousewheel| documentation on MSDN: | The onmousewheel event is the only event that exposes the wheelDelta | property. This property indicates the distance that the wheel button | has rotated, expressed in multiples of 120. A positive value indicates | that the wheel button has rotated away from the user. A negative value | indicates that the wheel button has rotated toward the user.
