+<p>
+ In <dfn>Stretch Mode</dfn>, the mouse pointer appears as an expanding
+ square symbol and is used to resize regions using a timestretch algorithm.
+ Resizing a region is done by <kbd class="mouse">left</kbd>-clicking on
+ the right-hand side of the region and dragging the edge to the desired
+ position; once the button is released a <kbd class="menu">Time Stretch
+ Audio</kbd> dialog will appear, as detailed in the dedicated <a href="@@stretching">
+ Stretching</a> page.
+</p>
+
+<h3 id="audition">Audition Mode</h3>
+
+<p>
+ <kbd class="mouse">left</kbd>-clicking on a given region using <dfn>Audition
+ Mode</dfn> will play the the session for the time span of that region.
+ The regions can also be <dfn>scrubbed</dfn> by
+ <kbd class="mouse">left</kbd>-clicking and dragging in the direction
+ desired; the amount dragged in one direction or the other will determine
+ the playback speed.
+</p>
+
+<h3 id="draw">Draw Mode</h3>
+
+<p>
+ In <dfn>Draw Mode</dfn>, the mouse pointer will change to a pencil; the
+ effect it will have depends on the type of track or region it is utilized
+ in.
+</p>
+
+<p>
+ In an <a href="@@audio-track-controls">audio track</a>, a green line will
+ appear in the region which is that region's <a href="@@gain-envelopes"><dfn>gain
+ envelope</dfn></a>. <kbd class="mouse">left</kbd>-clicking anywhere in
+ a given region between two existing <dfn>control points</dfn> will add
+ one to the region at the X-coordinate clicked on with the Y-coordinate
+ being on the line connecting the control points on either side of the
+ new one. <kbd class="mouse">left</kbd>-clicking on a control point will
+ allow it to be moved to any point in the region in between the control
+ points that bound it on either side of itself. And finally,
+ <kbd class="mouse">left</kbd>-clicking on a control point and pressing
+ the <kbd>delete</kbd> key or holding down the <kbd class="mod3n"></kbd>
+ key while <kbd class="mouse">right</kbd>-clicking on it will delete the
+ control point.
+</p>
+
+<p>
+ In an <a href="@@automation-lanes">automation lane</a>, if any automation
+ is defined in it, a green line connecting its control points will appear
+ in the lane. Control points in the lane are manipulated in exactly the
+ same way as they are in a region's gain envelope (see previous paragraph
+ for details).
+</p>
+
+<p>
+ In a <a href="@@midi-track-controls">MIDI track</a>,
+</p>
+<ul>
+ <li>
+ <kbd class="mouse">left</kbd>-clicking in a part of the track that has
+ no region, creates a one-bar long region, while <kbd class="mouse">left</kbd>-dragging
+ will create a region of arbitrary length.
+ </li>
+ <li>
+ <kbd class="mouse">left</kbd>-clicking on a region in Percussive mode
+ creates a diamond indicating a hit.
+ </li>
+ <li>
+ <kbd class="mouse">left</kbd>-clicking on a region in Sustained mode
+ creates a note whose duration is one <a href="@@grid-controls">Grid unit</a>,
+ while <kbd class="mouse">left</kbd>-dragging creates a note of arbitrary
+ Grid units length.
+ </li>
+</ul>
+
+<h3 id="edit-internal">Internal Edit Mode</h3>
+
+<p>
+ In <dfn>Internal Edit Mode</dfn>, the mouse pointer will change to
+ cross-hairs.
+<p>
+<ul>
+ <li>
+ On an automation lane, it allows to edit the automation
+ like the Draw tool.
+ </li>
+ <li>
+ On a MIDI region, it allows to lasso-select multiple notes at a time.
+ </li>
+ <li>
+ On an audio region, it displays the current level of the signal
+ and allows to edit the region gain like the Draw tool.
+ </li>
+</ul>
