Roll Spotlight

Rotates the spotlight about its own line of sight (the light’s local Z axis).

Reference

Although Roll does change the spotlight view, it affects the spotlight object only if the spotlight casts a rectangular beam or is a projector.

This button replaces the Zoom Extents button when a spotlight viewport is active.

Drag the mouse horizontally to roll a target spotlight or rotate a free spotlight about its local Z axis.
