A Cue List steps through a Chaser's scenes one cue at a time for theatrical operation

The Cue List widget attaches a Chaser and presents its steps as numbered cues. A single key press advances to the next cue — designed for theatre operators following a script. The side fader enables manual crossfade control, overriding the Chaser’s own fade times. Cue duration should be set to infinite (∞) for fully manual crossfade; the Speed Dial widget sets this. When paused, lights freeze in place including motors. Only Chasers can be assigned to a Cue List because Chasers are the only QLC+ function type with a duration parameter.

Examples

A theatre cue book mapped to a 50-step Chaser: the operator presses ENTER at each actor line. During a sunset crossfade they drag the side fader slowly.

Assessment

Why must a Cue List use a Chaser rather than a Scene or Collection? When should cue duration be set to infinite, and which widget sets it?
