Set Grid to clips and markers?

Just saw this video where someone PT grid to clips and markers , the separated a video by grid , not sure I’d use this very often, but it did seem really convenient for certain tasks, tried to do it but can’t find a N15 and you wanna achieve this?

If I understand correctly, just set the grid to Events and there you have it. Clips and Markers are all “events” so you have a grid based on the starts and ends of all events in the project.
