go check the thugpro launcher, you can look up the keybinds in there or set it to work with a controller.
however, default pc controls are something like WASD for movement, and the numberpad handles everything else. numpad 2 is ollie, numpad 4 is flip trick, numpad 6 is grabs, numpad 8 is grinds, 1 and 3 are getting on and off your board, 7 and 9 are for rotations.
