If those were not enough options you can also rotate about a specific atom directly with the turn command

        turn y 45 center #1/A:253 at CA

In the "Right Mouse" tab of Toolbar icons across the top of the window, there is "set pivot" icon which looks like a red circle with an arrow going around it and a red dot in the middle.  You can click that to assign the right mouse button to that function.  The mouse-mode icons and their meanings are given here.
