14. A method comprising:
rotating a drill bit to extend a wellbore into one or more subterranean formations; and
controlling pressurization of fluid in a communication channel from a bore in a body of the drill bit to a moveable element to thereby lock or unlock the moveable element,
wherein the method further comprises: linearly driving or rotationally driving a ported piston valve with a linear or rotary manifold in the bore to selectively couple a port in the ported piston salve with the communication channel, thereby establishing fluid communication between the communication channel and the bore.
