Single marker

Left-click and drag to move a single marker to a new location on the timeline.

Multiple markers

It is possible to move multiple markers by the same distance. Left-clicking each discreet marker, or Left-clicking the first and last markers of a range of markers selects them, then dragging one to a new location will move all selected markers together.

The markers are bounded by the zero point on the timeline. In other words, the first marker in your selection cannot move to the left of zero on the timeline.

Both ends of a range marker

Left-drag either end of the range marker. The other end will move by the same distance.
