Tricks HELP!!! (Tony Hawk's Underground 2)

Clamp
Left+VPro+8=4

You govorite about SpaceWalk ?
If so, could you explain in more detail.
Thanks in advance.

Let go and jump in the air press: 4(left) 6(right),8(grind)

do not understand what it means 4(left) 6(right)...?
4+left 6+right or what?...

Seen summer video one, where the trick was really cool
then bought the game, in editor tricks found this flourishes,
in my version is called Walking, but the problem is,
that it can be made part of the trick, but just sfintit while riding is impossible,
it means this trick must be one of the standard, I've tried everything
regular and special tricks, but found no need.
How to do this crap?

PS. since everyone has different ugly version of the translation, I explain the essence of the trick:
wagging my skateboard while riding on the rear wheels.

Damn, somebody write in Russian how to do this SpaceWalk, I just don't get it. Landed it a couple of times, and then me. Write PLZ !!!!!!!!!!
