+<h2>Single marker</h2>
+<p>
+ <kbd class="mouse">Left</kbd>-click and drag to move a single marker to a
+ new location on the timeline.

+
+<h2>Multiple markers</h2>
+<p>
+ It is possible to move multiple markers by the same distance. <kbd
+ class="mouse mod1">Left</kbd>-click each marker you want to move, then drag
+ one of the selected markers to a new location. All selected markers will
+ then move together. Note that 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.

+<h2>Both ends of a range marker</h2>
+<p>
+ <kbd class="mod1 mouse">Left</kbd>-drag either end of the range marker. The
