No MT on a H2O.
That said, even on a Forma, where MT gestures *are* supported, the "opposite corner" thingy for screenshots is nigh impossible to trigger.
EDIT: Okay, no, it works, I just have really, really short intervals configured (on purpose), so it needs to be a *super-fast*,*super-light* tap ^^.
In any case, as far as the OP is concerned, never gonna happen on a H2O anyway

. Long swipe it is, there.
