Rotating the head on a vertical axis???

Hi all, i've been looking everywhere to find the answer to rotating the head on a vertical axis only. For example if i look at someone in SL via camming them i'd like the head to look at them on a vertical axis and no other. Im not even sure if its possible but any feedback would be much appreciated. Thanks

I don't think this can be done. You can create an animation where the head moves only on the vertical axis but you can't make it work with your mouse camera movement. Maybe you can do it through scripting but I don't recall an commands could that control the head that way.
