<h2>Positioning the Playhead</h2>
<p>
The <dfn>playhead</dfn> is a vertical line with two arrows at each end
that indicates the current position of playback.
</p>
<h3>Positioning the playhead at the current pointer position</h3>
<p>
Pressing <kbd>P</kbd> will set the playhead to the current position of
the pointer, if it is within the editor track area.
</p>
<h3>Positioning the playhead on the timeline</h3>
<p>
A <kbd class="mouse">Left</kbd> click anywhere on the timeline (rulers)
will move the playhead to that position.
</p>
<h3>Positioning the playhead with the transport clocks</h3>
<p>
Click on either the primary or secondary transport clock and
<a href="@@editing-clocks">edit their value</a>
to move the playhead to a specific position.
</p>
<h3>Positioning the playhead at a marker</h3>
<p>
Click <kbd class="mouse">Right</kbd> on the marker and select either
<kbd class="menu">Locate to here</kbd> or <kbd class="menu">Play from
here</kbd>.
</p>
<p>
Alternatively, place the pointer on the marker and press
<kbd>P</kbd> to set the playhead.
</p>
<h2>Looping the Transport</h2>
<p>
When the <dfn>loop transport</dfn> button is pressed, the playhead will
jump the start of the loop range, and continue to the end of that range
before returning to the start and repeating.
While looping, a light green area is displayed in the time ruler over
the tracks to show the loop range.
</p>
<p>
By default, looping is bound to the <kbd>l</kbd> key.
</p>
<p>
For more information on defining and altering the loop range see
<a href="@@the-loop-range">Loop Range Markers</a>.
