Cues number is determined when recording a cue by filling in the Cue Number field. Cue numbers can have three decimal places (i.e., you can have 999 cues between cue 1 and cue 2, up to 1.999). If you are appending to the end of a cue list, Marquee will suggest a new cue number for you automatically based on the last cue number.
NOTE:
The record dialog box's Cue Number field is automatically filled in with the number of the cue where the Blue Box is sitting unless the Blue Box is sitting on the last cue.
If you want to re-number existing cues, see the topic called Renumber Cues for information on how to use the Move command.
