Fractal fill handles

Hi, could I ask a very short, at Fractal type fills how to change the fill handles asymetrically?

Basically I am trying Angelize's fractal tutorial from Xaraxone, and on the attached picture can be seen that the end fill handles are both pulled to the left. For me they are always in 90 degrees so maybe there is some keyboard short cut to pull them individually?

thanks,

Apologies, I should have included this in the tutorial. Hold down the shift key and click and drag the handle and you can skew and squash the fractals. This works with bitmap fills and transparencies as well.

Angelize never mind the tutorial is very good I can follow, just somehow this I was not aware at all. But now applied with pressing shift and it works of course, thanks
