Hi Bill,
You can use the command "cofr" with specified atoms (including "sel" as the specification if the atom or atoms are selected).

There are several different rotation modes, and you can switch among them using either "cofr" or the Rotation tool (under Tools... Movement in the menu).

I hope this helps,

My favorite way of viewing structures is for the rotation to be about a center of my choosing, as is common in many graphics programs (e.g. COOT). I would prefer to pick an atom on the screen and have this become the rotation center.  Is there a simple way to accomplish this in chimera? A small point perhaps, but one that is frustrating for me.......
