Newbie question: what is the numeric value identified with a movie clapboard icon for?

Perhaps a dumb newbie question, but in Patterns under Sequencer, that number identified with a movie clapboard icon, to the right of Next in either Shuffle All or Playlist… what is that for?

I checked the current v3 documentation and it doesn’t show up in that screenshot, and I can’t find the answer elsewhere.

Cheers,
