+ Under these buttons is the <dfn>Shuttle Speed Control</dfn> that
+ allows to <em>temporarily</em> scrub through the audio quickly. The slider
+ decides the playback speed: the further from the center it is set,
+ the faster the playback will scrub in both directions. The range of
+ this acceleration can be set by <kbd class="mouse">right</kbd>
+ clicking the control and setting the multiplier, between 1.5
+ (± 150%) and 8 (± 800%).

<p>
- The Shuttle Speed Control supports 2 operating modes, that can be chosen with
- <kbd class="mouse">right</kbd> click > Mode:
+ The <kbd class="menu">VS</kbd> (for <em>V</em>ari<em>S</em>peed)
+ button sets a <em>constant</em> playback/record speed. It can be set
+ in semitones (1 semitone = × 2 <sup>1⁄12</sup> ≈
+ 105,9%), or cents of semitones, and is armed/disarmed by clicking the
+ button. Whether or not this VariSpeed is persistent when
+ stopping/restarting transport depends on the <kbd class="option">Reset
+ default speed on stop</kbd> parameter in the <a
+ href="@@preferences#preferences-transport">Preferences</a>.
</p>
-<ul>
- <li><dfn>Sprung mode</dfn> that allows for a temporary scrub: it only scrubs
- while the mouse is left clicked on the control.</li>
- <li><dfn>Wheel mode</dfn> that allows to set a playback speed until the "Stop"
- button is pressed, which stops the playback and resets its speed.</li>
-</ul>
+<h4 id="transport_sync">Transport Sync</h4>
<p>
On the left of the slider is the positional sync button (which might show <dfn>Internal</dfn>,
or <dfn>MTC</dfn> or several other values), than can be used to control whether or not the
synchronization source, such as MIDI Time Code (MTC), Linear Time Code (LTC) or JACK
(see <a href="@@timecode-generators-and-slaves">Timecode Generators and Slaves</a>).

+<h4 id="transport_status">Transport Status</h4>
<p>
The current playback status (Stop, Play, or speed %) is shown on the right of
the speed slider.
