How do you perform stunts?

[Paratech2008]

I can race ok, but forget pulling off stunts, which is needed in story mode.

I'd appreciate some advice, thanks in advance.

You can redo the in-game tutorial to see how if my explanation is miserable. To preform stunts you have to do key combinations like pressing the left arrow and D together and then the down arrow and S together to do the volt stunt.

yes it is hard isnt it...the stunt list shows 2 up arrows or 2 downs...
as above its key combos...like up and W or down and W or two S's etc
