[PyMOL] setting stereo separation distance in pymol

[Sri Krishna Subramanian]

Dear all,
        I am new to this list and apologize if this question has been
asked before. I am trying to figure out if it is possible to set the
stereo separation in PyMOL while viewing the molecule interactively. I
want to see the protein using wall-eyed stereo and would like to bring the
left and the right images as close as possible. Again my question concerns
stereo when using PyMOL interactively and not while making ray traced
publication quality images.
thanks for your help.
