Moves the spotlight along its line of sight.
The buttons on this flyout replace the Zoom button when a spotlight viewport is active.
Neither free cameras nor free spots have targets. When you activate one of their viewports, the navigation button appears as a flyout, but only Dolly Camera or Dolly Spotlight is available. If you reactivate a viewport belonging to a targeted object, the three choices are again provided.
Dolly Spotlight: Choose this option and drag the mouse to move only the spotlight to and from its target. If you go past the target, the spotlight flips 180 degrees and moves away from its target.
Dolly Target: Choose this option and drag the mouse to move only the target to and from the spotlight.
Dolly Camera + Target: Choose this option and drag the mouse to move both the target and the spotlight to and from the spotlight.
When you dolly a spotlight, the light source moves closer and away from its target. Dollying a spotlight closer to its target causes the area illuminated at the target to shrink. Dollying a spotlight away from its target causes the area illuminated at the target to expand.
