A Timeline asset must be open in the Timeline window for the Add Markers button to be enabled.
Click the Add Markers button to place beat markers on the currently inspected Timeline asset’s marker track.
If a beat marker already exists at the same time position, it will be overwritten by the new marker.

Once placed, beat markers appear on the Timeline’s marker track.
Clicking the Timeline Markers toggle (the pin icon highlighted in the image) to expand the marker track enables events on the Timeline to snap to the markers. This makes it easier to place events in sync with the music rhythm.
Each marker has a tooltip showing its position in bar.beat format. Markers on beat 1 of each bar are highlighted in red.
