combined key and touch combinations

[UltraBlackLinux]

I'm using a pretty tiny screen, and for lack of space I'd like to use key combinations to expand the possible touch gestures, as the most I can fit on screen comfortably is two fingers, which leaves not many combinations for use.

I'd for example like to open the context menu without automatically triggering a window move like so:

bindm = , longpress:1, exec, ydotool click 0xC1
# while having
bindm = $mainMod, longpress:1, movewindow

Could you implement that?
Thanks!
