When I want to replace swipe laterally with two fingers (I don't know what the exact translation is) with the previous gesture (Snow Leopard's), the three-finger move, and then I try to use this in Safari, the app crashes immediately. It then displays the crash report which says there was an error with this plugin: AirKeysInputManager. How can I solve this issue?
Also, do you know if it's possible to customize Mission Control's gesture? I'd like to swipe downwards instead of having to swipe upwards.
