<p>Many editing operations in Ardour require you to first select one or more regions that you want to change in some way. You can select a single region, or multiple regions, including regions in different tracks. When you select a region, it will appear in a darker color than unselected regions.</p>
<p>Note that if a track is a member of a group that is active and has the "Select" property enabled, then Ardour will attempt to match whatever selections you make in one track across every other track of the group. See <ahref="/working-with-regions/region-selection-equivalence">Selection Equivalence</a> for more information on precisely how selections will be propagated to other tracks.</p>
<p>Please read <ahref="/working-with-tracks/selecting-tracks/region-and-track-selection">Region & Track Selection</a> for more information on how selecting regions and selecting tracks interact.</p>
<p>Confirm that you are using the <ahref="/ardours-interface/introducing-the-editor-window/the-editing-toolbar/#object">Object tool</a>, then click on a region to select it. If <ahref="/ardours-interface/introducing-the-editor-window/the-editing-toolbar/#smartmode">smart mode</a> is enabled, click in the lower half of the region.</p>
