While holding onto the "use" button, there are some ways to change directions.

1. I call it the nooby way where you hold "forward" only and look left to turn left or look right to turn right. This will make you look perpendicular to where you are actually going. In other words, you are not going to face straight.

OR what I do...

2. Without pressing "forward" or "back", you press "strafe left" ONLY and look left to turn left while looking straight. Or you can "strafe right" ONLY and look right to turn right. This works excellent with parachutes or admins who decides to turn the gravity to less than 200. In LostWorld when you dismount the airplane to get into the island, I can already head to the breakable gate and past the ramp before I land. To do that, you will have to alternate turning left and right.

If you're confused, tell me or go on IBIS and practice around...experiment a little bit.
