With each subsequent press of a shortcut key it would toggle/cycle through the variants of selected feature cycling through all options in a continuous loop in case you overshoot it. An example as follows:
press C one time => Centre Diameter Circle
press C one times => 2 Point Circle
press C one times => 3 Point Circle
press C one times => 2 Tangent Circle
press C one times => 3 Tangent Circle
press C one times => Centre Diameter Circle (loop starts again)
This can also be done for other options like, square, arc, etc..
