+<p><strong>Sequence Feature Settings Dialog Box</strong></p>
+<p>Select <strong>View→Feature Settings...</strong> menu entry
+in an alignment window to open the feature settings dialog box, which
+allows you to precisely control the presence and appearance of sequence
+features for the current alignment.</p>

+Sequence Feature Settings for the Jalview Application</img></center>
+<p>The top section of the dialog box lists all the sequence feature
+groups, along with a tickbox for each that controls whether its features
+are displayed. The table in the middle lists all the features in the
+currently selected groups, along with their display style and whether
+they are currently being displayed (only the ticked features and groups
+are displayed). <strong><em>You can change the colour or
+shading style used for a feature in the associated alignment by clicking
+on its colour box.</em></strong></p>
+ <p>
+ <a name="selectbyfeature"><strong><em>Selecting
+ alignment columns by feature</em></strong></a><br> <strong>Double-clicking
+ a feature type</strong> allows you to select columns in the alignment that
+ contain (or do not contain) features of that type. If a region of the
+ alignment is currently selected, then only features in the current
+ selection will be searched. The following keys affect the way in which
+ selections are made:
+
+ <ul>
+ <li>Hold down <strong>Alt</strong> to select columns not
+ containing features of a particular type.
+ </li>
+ <li>Hold down <strong>Shift</strong> to add columns to the
+ current selection.
+ </li>
+ <li>Press <strong>Command/Windows key</strong> to toggle column
+ selection state (XOR)
+ </li>
+ </ul>
+ Options are also provided in the feature's pop-up menu (see below).
+ <br />
+ <em>Select columns by feature was added in Jalview 2.8.1</em>
+ </p>
+ <p><strong><em>Feature settings pop-up menu</em></strong><br>
+<strong>Right-click</strong> on a feature to open a pop-up menu that
+allows you to sort the alignment or current selection using that feature
+type (see below), or toggle the type of colouring used for the feature.
+Features may be highlighted with either a single colour or a <a
+ href="featureschemes.html">feature colourscheme</a> based on either the
+scores associated with that feature or from the feature's description
+(e.g. to distinguish different names associated with a DOMAIN feature).</p>
+<p><strong>Ordering alignment by features</strong><br>
+The 'Seq Sort by Score' and 'Seq Sort by Density' buttons will sort the
+alignment based on the average score or total number of currently active
+features and groups on each sequence. To order the alignment using a
+specific feature type, use the <em>sort by ..</em> entries in the pop-up
+menu for that type.<br>
+<em>Feature sorting and graduated feature colouring was introduced
+in jalview 2.5</em></p>
+
+<p><strong>Transparency and Feature Ordering</strong></p>
+<p>It is important to realise that sequence features are often not
+distinct and often overlap (for example, a metal binding site feature
+may be attached to one position along a stretch of sequence marked with
+a secondary structure feature).</p>
+<p>The ordering of the sequence features in the dialog box list is
+the order used by jalview for rendering sequence features. A feature at
+the bottom of the list is rendered <em>below</em> a feature higher up in
+the list.<br>
+<em><strong>You can change the order of a feature by
+dragging it up and down the list with the mouse</strong></em>.</p>
+<p>The <strong><em>Optimise order</em></strong> button (currently
+only available in the application) will re-order the feature render
+ordering based on the average length of each feature type.</p>
+<p>The <strong><em>transparency slider setting</em></strong>
+(currently only available in the application version) controls the
+visibility of features rendered below other features. Reducing the
+transparency will mean that features at the top of the list can obscure
+features lower down, and increasing it allows the user to 'see through'
+the upper layers of a set of features.</p>
+<p><strong><em>You can save all features, with their
+current colours and visibility in a Jalview format file. </em></strong></p>
