does any one know how to use a keyboard for dunk contest?

guys pls help me i dont know how to use my keyboard as control for the dunk contest. i cant lob, can any one pls help

thanks in advance

if u want to slam dunk im the contest u need to:
1. move your playa outside the 3-point line
2. press and hold 1 of 2 buttons(superstar trigger or acceleration)
3. press any move key: rebound, pass, dunk, shot, when you begin to atack the basket
4. press the move key again (any key) and hold it
strongly recomended combo: supstar trigger + shot, shot - playa will dunk betwen 2 legs!! try it infront the basket, and from the corner!
