What settings can be changed on your Canon's RF lens control ring?

The EOS R system introduced RF lenses with a control ring around the lens body in addition to the usual focus and zoom rings. It controls a range of functions, from basic exposure to autofocus and image settings. 

The position of control rings is different on different Canon leness, making it more difficult to find instinctively if you use a range of lenses. In this respect, using EF lenses with the control ring mount adapter is better as the control ring remains in the same location.
