Use markers with audio
When you add project markers to the Timeline, they appear in the Timeline and Keyframe
Editor. You can use project markers to designate “hit points” as you play the project, to jump to a
specic point or to highlight points to synchronize visual and audio events.
For information on adding and deleting markers, moving markers, editing marker information,
and using markers, see Markers overview on page 286.
