 <h2>Setting Track Visibility via URL</h2>
 <h6>How do I create a custom URL to control the visibility of specific tracks?</h6>
 <p>
 You can control the visibility of tracks from the URL with the following parameters, 
 each linked by the "&amp;" sign, similar to position parameters. For more information, please see
 the <a href="../goldenPath/help/customTrack.html#optParams" target ="_blank">optional URL 
 parameters</a> section of the Custom Tracks User's Guide.</p>
 <ul>
 <li><code>hideTracks=1</code> - hides all tracks</li>
 <li><code>&lt;trackName&gt;=hide|dense|pack|full</code> - sets specified track or subtrack to a
 chosen visibility</li>
 <li><code>textSize=&lt;number&gt;</code> - sets browser text size to either 6, 8, 10, 12, 14, 18,
 24, or 34. Default is a textSize of 8.</li>
-<li><code>ignoreCookie=1</code> - removes pre-existing user settings like track seletion, custom
+<li><code>&lt;trackName&gt;.heightPer=&lt;###&gt;</code> - sets a bigWig track's height to a 
+particular number of pixels (between 20-100)</li>
+<li><code>ignoreCookie=1</code> - removes pre-existing user settings like track selection, custom
 tracks, and track hubs</li>
 </ul>
 <p>
-For example, you can use the following command to hide every track (hideTracks=1) and set the knownGene track to 
-the pack visibility (knownGene=pack):</p>
-<p><code><a href="../cgi-bin/hgTracks?db=hg38&hideTracks=1&knownGene=pack">http://genome.ucsc.edu/cgi-bin/hgTracks?db=hg38&hideTracks=1&knownGene=pack</a></code></p>
+For example, you can use the following command to hide every track (hideTracks=1), set the
+genome database to hg38 (db=hg38), set the mappability track to full visibility (mappability=full),
+and set the umap track height to 100 pixels (umap24Quantitative.heightPer=100). Each of these 
+parameters can be used individually or in combination.</p>
+<p><code><a 
+href="../cgi-bin/hgTracks?db=hg38&ignoreCookie=1&hideTracks=1&mappability=full&umap24Quantitative.heightPer=100">
+http://genome.ucsc.edu/cgi-bin/hgTracks?db=hg38&hideTracks=1&mappability=full&umap24Quantitative.heightPer=100</a></code></p>
 
 <p>Composite tracks have additional URL parameters that encode options to hide, select, and 
 display subtracks.</p>
 <ul>
 <li><code>&lt;trackName&gt;_hideKids=1</code> - hides a specific composite track's subtracks</li>
 <li><code>&lt;trackName&gt;_sel=1</code> - selects specific subtrack to be 'checked', allowing
 display</li>
 </ul>
 <p>For example, the following URL hides all tracks (hideTracks=1), hides a specific composite
 track's default subtracks (refSeqComposite_hideKids=1), turns on one specific subtrack 
 (ncbiRefSeqCurated=full), and checks a box to display that subtrack 
 (ncbiRefSeqCurated_sel=1).
