<title>Track trial-and-error solutions</title>
 <p>
Trackers can be used to keep track of trial-and-error solutions. Tracked moves are entered in a different color to help make the moves visually distinct from moves made earlier in the game. This feature is particularly useful when solving difficult games. 
  </p>
<p>Using the tracker:</p>
<steps>

   You can toggle the tracker interface in one of the following ways:
  </p>

   <item><p>Click <guiseq><gui>Tools</gui><gui>Track Additions</gui></guiseq>.</p></item>
   <item><p>Click <gui>Track Additions</gui> in the toolbar. If the toolbar is not visible, click <guiseq><gui>Settings</gui><gui>Show Toolbar</gui></guiseq>.</p></item>
  </list>
  <note><p>
