+ The clock, as with all other clocks, can be <kbd
+ class="mouse">right</kbd>-clicked on to choose the desired <a
+ href="@@editing-clocks">time representation</a>. The menu also allows :
+</p>
+
+<ul>
+ <li><dfn>Set from Playhead</dfn> : the clock is the current position of the playhead</li>
+ <li><dfn>Locate to this time</dfn> : moves the playhead to the the clock time</li>
+ <li><dfn>Copy to clipboard</dfn> : copies the clock (with formatting) to the clipboard.</li>
+</ul>
+
+<p>
+ Combining these three options allow to e.g. memorize the current
+ playhead position (<em>Set from playhead</em>) and reposition the
+ playhead (<em>Locate to this time</em>) at that position after
+ another edit.
+</p>
+
+<p>
+ If there are no selected objects, the nudge controls can be used to
+ move the playhead backward or forward by the amount shown on the
+ clock.
