BetterTouchTool is an APP that you can download.
It offers advanced programming of the (multi)gestures of the TrackPad (but also of the build-in trackpad)
For example:
I programmed that swiping three fingers up puts me in Write mode; three fingers swipe down puts me in Engrave mode.
Three fingers tap shows or removes the panels ; 4 fingers tap shows/ hides full screen mode etc.
Good Luck !
