[SOLVED] Where can i learn about VehicleSeat?

I need to know how to work with VehicleSeats because they can fire multiple input events at once. Searched in YT and wiki but i find nothing useful from it. Can someone explain or send me a link of what site can i use to learn? (Maybe a propertie that fires when i press W?)

OBS: (I'm not asking a code, just some help)
