i can't get the number hotkeys to work and i've tried everything, clicking, highlighting then pressing a number, i don't understand how to do it, everything says to do it one way or the other and i've treid them all.
For future people who find this topic, to set the number bar hotkeys:
Open the customize menu.
Select any pallet location (you don't have to change it if you don't want to).
Hover over an action.
Press the number you wish to bind it to. That number will appear next to it. It is now bound.
