Rotate around selection?

 From:  3DKiwi

Is it possible to rotate around what you have selected?

In Cinema 4D for example if you have an object, points, edges or polygons selected when you rotate your view the centre of the selection is the pivot point. I would like to be able to do this MoI. Possible?

Thanks
