what is this blue line in the montage?

always wondered what this line was in the montage… it’s not movable and always shows up between tracks:

that blue one between the end of the track and the start of the next one…

It’s a cue point, customizable there:

That allows snapping a clip with the next one, at a distance.

ah, ok… thanks! i’ll look into that functionality…
