Comment on USB Overdrive

I'm a keyboard person but I have a Logitech MX310 and didn't want to waste the extra buttons. I decided to map various Expose and Dashboard functions using USB Overdrive, which makes more sense to me than hitting F9 - F12 since Expose and Dashboard are basically mouse-centric functions.

Tip: You can have something happen when you scroll your mousewheel while it is clicked, so even with a basic scroll mouse you have two actions available (clicked wheel up and clicked wheel down). No need for monster 10-button mice.
