The verb jIrmoH "crank" can be used for turning a doorknob. If it's important to distinguish between the doorknob turning only to the point of the door opening as opposed to turning around several times, as with the combination lock on some safes, you can say things like wa'logh jIrmoH "turn once, crank once" or jIrmoHtaH "keep turning, keep cranking." When context is clear, jIrmoH alone is fine. But that's if it's a doorknob that you rotate. If the door-opening gizmo is the kind of handle that's shaped like an L, with one leg of the L sticking into the door and the other leg grabbed by your hand, you'd use ghuj or ghujmoH "pivot, swivel."
