Now I have to think about what I could do with them! Did someone got a clever idea there?
I tend to use my two handed gestures for the less common windows tasks like passwords, windows keys - ie win d, win e etc and pop up menu (one finger and thumb).
I also like to start up an app by taping two fingers. Something like ctr+alt+shift+p for photoshop. (which is applied by clicking the properties of the app icon on the desktop and assigning the above shortcut.)
Also media keys like mute volume are better out of the way up there as I need more valuable gestures for my single hand(s).
Alt+enter is on both 4 finger tap and ctrl alt delete is up there.
