Abstract
A system for reversibly rotating a shaft for operation of the control system in a covering for an architectural opening includes two relatively linearly moveable members at least one of which has a low friction component engaging a helical path on the other so that linear movement of the members causes relative rotation to drive the rotatable shaft of the control system.
