-<h2>How To Play Back Individual Slots</h2>
+<p>
+ It is possible to play both individual clips and entire cues.

-<p>By clicking play button. FIXME</p>
+<h2>Playing Individual Clips</h2>
-<p>By scrolling the mouse wheel. FIXME</p>
+<p>
+ There are generally two ways to trigger a slot with a clip inside.
+</p>
-<p>Stopping the slot playback. FIXME</p>
+<ol>
+ <li>Pressing a mouse button over the button to the left of the
+ clip's name (Ardout defaults to Trigger launch style which has a classical
+ triangle playback icon)</li>
+ <li>Sending a note-on event from an external or a virtual MIDI
+ controller</li>
+</ol>
-<h2>How To Play Back An Entire Cue</h2>
+<p>
+ How Ardour responds to releasing the mouse button or sending a note-off
+ event depends on the trigger launch style.

+<ul>
+ <li>Clip progress, in the form of a sliding pie chart</li>
+ <li>Which cue is playing (it's C on the screenshot)</li>
+ <li>MIDI clip indication, an icon representing two beamed 1/16 notes</li>
+ <li>Follow count, e.g. '1/2' on the screenshot means the clip is currently being played
+ the first time out of two times total</li>
+</ul>
+
+<p>
+ One way to stop a playing clip is to click the square-shaped icon
+ in any of the empty slots in the track of interest.
