Signature Dunks

How do you Do those signature Dunks like Mj's or any other player and what the control on the keyboard? thanks if anybody help me

nobody want's to help nice!

It's not that we don't want to help. I don't think anybody knows. My guess would be to press the shot stick towards the basket when attempting a dunk. If you are using absolute right stick shooting, you may just have to push up on the right stick.
