Havent tried yet but would it be possible to have hypershift key switch, and when you select a hypershift programed button and then revert to standard settings after the hyper assigned button selection be a possiblity.
Or in gamer speak I want a weapon that is assigned to hypershift mouse button keep the weapon and then revert back to the (standard or most used) buttons so while I’m flying away with the tau I can switch to a crossbow and kill :-)
