A cord lock engaged with a vertically moveable handle for selectively engaging and disengaging a cord for transporting vanes in a blind. A rotatable mechanism is proximate with a vertically moveable handle. An extension is attached to the rotatable mechanism, and a cord lock is engaged with the upper end of the extension so that rotation of the rotatable mechanism and extension operates the cord lock to selectively engage the cord. Following such engagement, the handle can be pulled to move the cord and to transport the vanes. The rotatable mechanism can be rotated in the opposite direction to disengage the cord lock from the cord.
