Good

I suspect that you are just making a joke about my suggestion, but what you suggest would require remembering the cursor position while select-all is done, which most editors do not do (the cursor is one end of the selection). Also cyclic modes are a very bad idea, though they were popular with some older Unix editors, they are not user-friendly as the user has to watch to get them to stop, rather than just blindly hitting the key many times to get at the state they want (if it is the last state).
