Okay, I rarely just try out an app on a cold recommendation - but I say buy this app. Or give it a try for 32 days, then buy this app. Cost after 32 days is $4.99
The app allows you to customize your own gestures for the Tablet device. There are built-in gestures already set up, which can be enabled by just pressing a "copycat" button. I use those, and added a few more.
I am now using gestures like 5-finger pinch to jump to the Start Screen, 5-finger spread to jump to the Desktop, 2-finger swipe up to start the keyboard, 2-finger swipe down to close the keyboard, 4-finger swipe left to lower volume, 4-finger swipe right to raise the volume, 3-finger pinch to lower brightness, 3-finger spread to raise brightness, saves to all your devices if you wish (via OneDrive), and... oh, well...
Just buy this app.
