I just figured there needs to be a possibility to create your own gestures and map them to your own commands. But here is my proposal.
One and two finger gestures are used to navigate the timeline and to mark and cue. Three finger gestures are mostly used for inserting and switching to the source viewer. Four finger gestures are all about trimming and five finger gestures are Undo, Select All Tracks etc.
One important thing is the thumb. Since the thumb is no finger in the strictest sense

It will work like a modulator key. Allowing the same gesture to be recycled for a related command.
I left jogging and shuttling out of this list because they are special and one of the most important things for this to work properly. I will post about this later on. Basically they are circling for joggling and two fingers wiped to the left or right and then holding for shuttling.
When you are required to wipe in a certain direction I use capital letters (e.g. DOWN). To announce that you have to lay your thumb down, I wrote T hold. The number in the front indicates how many fingers you need to perform the gesture. The entries in this list marked with an asterisk (*) require a macro or are not possible yet this way but I think it’s worth thinking about them anyway.
1 Tap - Mark
1 UP - Unmark
1 LEFT - Swap
1 RIGHT - Swap
2 Down - Play
2 Tap - Stop
2 UP Reverse
3 LEFT - Jump Left
3 Right - Jump Right
T hold + 3 LEFT - Start of Timeline
T hold + 3 RIGHT - End of Timeline
2 Pinch - Mark All
2 Unpinch - Mark All from start of clip*
T hold + 1 Tap - Cue
T hold + 1 UP - Uncue
3 Tap - Switch to Source/Rec Viewer
3 DOWN - Insert
3 UP - Delete (and Empty Cut)
Hold ring and point finger + middle finger DOWN - Replace
Hold ring and point finger + middle finger UP - Remove
T hold + 3 UP - Pop out original and load in source viewer*
T hold + like Replace - Backtime
T hold + like Insert - Fill
4 Tap - Preview
4 LEFT - Trim last out
4 UP Trim in
4 DOWN - Trim out
4 RIGHT - Trim next in
4 Pinch - Join/Unjoin
4 Unpinch - Move cut (roll edit)
5 LEFT - Undo
5 RIGHT - Redo
5 Pinch - Select All Tracks
5 Unpinch - Delselect All Tracks*
5 UP - Move Track
What makes this easy and special? Imagine you want to make a slip edit. All you do is combining UP and DOWN with four fingers and there you are. My favourite is the possibility about a top and tail edit. Unpinch with two fingers and wipe 3 finger UP. This is very fast and all you do is combining gestures you use a lot anyway.
So you don’t have to reach for far lying key combinations. And most of all: You certainly don’t have to look down and miss an important frame. Also: Gestures like mark and stop are the easiest so these will be very responsive by design.
