With each subsequent press of a shortcut key it would toggle/cycle through the variants of each one, eventually cycling through all options in a continuous loop in case you overshoot it. An example as follows:
Press #) Shortcut Key = Result
1) C = Centre Diameter Circle
2) C = 2 Point Circle
3) C = 3 Point Circle
4) C = 2 Tangent Circle
5) C = 3 Tangent Circle
6) C = Centre Diameter Circle
This would follow suit for all of the individual variants of the other keyboard shortcuts that have been added so far; and hopefully all future ones. I have attached the image for key mapping as provided in the September release for reference.
