Roll Angle Manipulator
To change the roll angle of a target light, you can use a manipulator. This can
be useful if the light does not cast a round beam, or if it is a projector light
(see
Advanced Effects Rollout on page 5108). To display the manipulator, select
the light, right-click it, and then click Roll Angle Manipulator Toggle on the
Tools 2 (lower left) quadrant of the quad menu.

object and then turning on
Select And Manipulate on page 2613 on the main toolbar.
