ooooof i had to do that when i started the game cuz i didnt have a mouse. i did it so weird, i used arrow keysso i had to quickly tap the spacebar when i wanted to jump because i would take my hand of the trackpad
my trackpad won't work at all if you stop moving it while using wasd, you have to decelerate and let the trackpad cool down or you will fry its receptors and it wont work
