can't access z symetry

If I create a Zsphere and press X I can draw in symetry in X plane. When I choose the z symetry pressing Z I get nothing. Do any wise members know where I’m going wrong.
I am following a tutorial where I press x and z to draw in both axis but all I can do is make the Z symmetry to draw.

In ZBrush 3, pressing X turns on symmetry or turns it off. To change symmetry modes you need to manually use the switches in the Transform palette. You can, however, assign hotkeys to the Y and Z switches.

Thanks for the reply Auric, I just found it in the transform menu. see you round the forums.
