Heys, On my MBA, I like the four fingers up to show desktop and four fingers down to do Expose. I understand all window Expose is now merged with Spaces to form Mission Control, and am aware of the new three finger gestures, etc, but (with customisation) is the four finger Snow Leopard setup still possible in Lion? How much can these gestures be changed out of the box (so to speak)? I've been searching the forums and Google but haven't found anything definitive. Just curious!
