Edit 2: Title is wrong, I meant Right Touch Pad, not Left Stick.
I am trying to use a radial menu for movement in a game and it works ok, however I have to continually tap the direction in order to move. I'd like for it to keep pressing that action so long as my finger is on the region of the touch pad I'm on. That is: have similar behavior to if I just hold a key down.
For context, I know this is a little screwy, but the game I'm playing (Caverns of Qud) uses Numpad for movement including 7/9/3/1a
