I just upgraded to Lion. (Yes, I'm slow but I didn't really like the features of Lion.) Anyways, after a fresh install, I noticed that there were no gestures for show desktop? I see the one where it's using the thumb and three fingers but I can't change that to something else? IIRC, I slid for fingers up/down for show desktop in SL. Is there any easy shortcut for show desktop besides hot corners?
