<p>
Tracks and busses can be put into <dfn>groups</dfn>. Members of a group
can share various settings&mdash;useful for managing tracks that are closely
related to each other. Examples might include tracks that contain
multiple-microphone recordings of a single source (an acoustic guitar,
perhaps, or a drum kit).

<p>
Tracks and busses can be grouped in various ways. In the editor window,
a track's controls might look like the adjacent image.
</p>
<p>
The green tab to the left of the track header indicates that this track
is in a group called <samp>Fred</samp>. These tabs can be dragged to add
adjacent tracks to a group.
</p>
<h2>Create New Groups</h2>
<p>
There are several ways to <dfn>create groups</dfn> for tracks and busses:
</p>
<ul>
<li><kbd class="mouse">Right</kbd>-clicking on the group tab and using one of the <kbd
class="menu">Create&hellip;</kbd> options there. A group can be created with
no members, or one that starts with the currently selected tracks, or
record-enabled tracks, or soloed tracks.</li>
<li>Alternatively, clicking the <kbd class="menu">g</kbd> button on a track header to open the
Group menu. The menu lists the available groups. Selecting one of these
groups will add the track or bus to that group. The menu also allows creating
a new group.</li>
<li>Finally, the <a href="@@groups-list">Groups list</a>
has a <kbd class="menu">plus (&plus;)</kbd> button at the
bottom of the list that can be clicked on to create a new group.</li>
</ul>
<h2>Remove Groups</h2>
<p>
Context-clicking on a <dfn>group tab</dfn> and selecting <kbd class="menu">Remove
Group</kbd> from the menu removes it. Removing a group does <em>not</em> remove
the members of a group.
</p>
<p>
Groups can also be removed by selecting them in the <a href="@@groups-list">Groups list</a>
and then pressing the <kbd class="menu">minus (&minus;)</kbd> button at the bottom of the list.
</p>
<h2>Add/Remove Tracks and Busses From a Group</h2>
<p>
Clicking the <kbd class="menu">g</kbd> button displays a menu with a list
of the available groups. Selecting one of these groups adds the track or bus
to that group. Selecting <kbd class="menu">No Group</kbd> removes it.
</p>
<p>
Alternatively, a group tab can be dragged to add or remove tracks from
the group.
</p>
<h2>Activate/Deactivate Groups via the Group Tab</h2>
<p>
Clicking on a group tab toggles the group between being active and inactive.
An inactive group has no effect when editing its members. An active group
will share its configured properties across its members. Tabs for disabled
groups are coloured grey.
</p>
<h2>Modify Group Properties</h2>
<figure class="right">
<img src="/images/route-group-dialogue.png" alt="The Track/bus Group dialog">

</figcaption>
</figure>
<p>
Edit the properties of a group is done by <kbd class="mouse">right</kbd>-clicking
on its tab and choosing <kbd class="menu">Edit Group&hellip;</kbd>. This opens
the track/bus group dialog, which is also used when creating new groups.
</p>
<h3>Group Color</h3>
<p>
Clicking on the color selector button changes a group's color. This affects
the color of the group's tab in the editor and mixer windows. The color does
<em>not</em> affect the color of the group members unless the shared
<kbd class="menu">Color</kbd> property is enabled.
</p>
<h3>Shared Properties</h3>
<p>
<kbd class="option">Gain</kbd> means that the track faders will be synced to
always have the same value; <kbd class="option">Relative</kbd> means that the
gain changes are applied relative to each member's current value. If, for
example, there are two tracks in a group with relative gain sharing, and their
faders are set to &minus;3&nbsp;dB and &minus;1&nbsp;dB, a change of the first track to a
gain of &minus;6&nbsp;dB will result in the second track having a gain of
&minus;4&nbsp;dB (the <em>difference</em> of the gains remains the same).
</p>
<p>
<a href="@@bus-controls#mute"><kbd class="option">Muting</kbd></a>,
<a href="@@bus-controls#solo"><kbd class="option">Soloing</kbd></a>,
<a href="@@audio-track-controls#record"><kbd class="option">record enable</kbd></a>,
<a href="@@the-tracks-and-busses-list"><kbd class="option">active state</kbd></a>,
<a href="@@track-color"><kbd class="option">color</kbd></a> and
<a href="@@monitoring"><kbd class="option">monitoring</kbd></a>
are all straightforward. They simply mean that all member tracks or busses will
share the same settings in these respects.
</p>
<p>
<kbd class="option">Selection</kbd> means that if a region is selected or
deselected on one member track, <a href="@@corresponding-regions-selection">corresponding
regions</a> on other member tracks will be similarly selected. Since region
editing operations are applied to all currently selected regions, this is the
way to make edits apply across all tracks in the group.
</p>
<h3>Group Tab Context Menu</h3>
<p>Context-clicking on the group tab offers a further menu of group-related actions. </p>
