Cue halts playback and recording, then makes the cue point visible on the server output.
The cue point is any desired frame that has been marked previously. If no frame has been marked, the cue point defaults to the first frame of the item.
Press this button twice in order to preview the out point of the item. The server cues to a point five seconds before the marked out point, or before the last frame if no out point is marked, and is ready to play to the end of the item.
