How do you get qualifyed for the custom levels on marble blast gold

this will only work on mac comps OK.
press command, fn and f10 all at the same time and a toolbar(?) will come up.
in the space type $testcheats=1; and press return and press command fn and f10 again to close the toolbar(?).
press command fn and f11 and after that you should be able to drag stuff around with the mouse.
