above the pad there is a disabling button. so when you type, when your wrist touches the pad, it doesn't move the pointer. the 2 buttons on the bottom are standard clicking buttons. there are "scrolling areas" on it also, they work just as a mousewheel would (up-down, side-to-side). it is really an AWESOME pad. I was at BB today and checked out the build of toshiba lappys (see my sig) and the toshiba pad is SO MUCH CRAPPIER!
