Is there any way to customise the trackpad gestures on the surface book? For example, a 3 finger tap opens Cortana (or action center if you wish), but can I change it to act as a middle click? Can I use a two finger swipe back to go back a page in Edge? Or a three finger drag to move windows around (like in OSX)? Is there any way (even third party extensions) to achieve this? Thanks so much for your help!
