forward forward on Dpad:

FF

on mouse:
Forward, backward, forward.

on Dpad:
forward, down, HOLD downforward.
one simple forward, then down and slide toward forward.

on mouse?
foward,  back, down, and you have to draw a freaken curve.


good luck with that.

not to mention it's impossible hold down a direction with a mouse.

not to mention precisions.

forward is a simple light press.
vs
a mouse movement to the right, if too long, you a simple press would turn into SOMETHING LIKE a hold down forward.
if too short, then it would be an awkward brake.
