-<p><strong>Hidden Regions</strong> </p>\r
-<p>Use the keyboard key "H" to hide / reveal selected columns and sequences. \r
- To hide / reveal only selected sequences, use "Shift H", to hide / \r
- reveal only selected columns, use "Control H".</p>\r
-<p><strong><em>Hiding Sequences</em></strong><br>\r
-To hide selected sequences in an alignment, use the <strong>"View \r
- -> Hide -> Selected Sequences"</strong> menu item or simply select <strong>"Hide \r
- Sequences"</strong> from the Popup menu after a right click on the sequence Ids. \r
-</p>\r
-<p>Hidden sequences will not be used in any calculations, editing or web service \r
- alignments performed on visible sequences. </p>\r
-<p><strong><em>Hidden Sequences Representatives</em></strong><br>\r
-A more advanced hide involves a right-mouse click on a sequence, then selecting \r
- <strong>"SequenceID -> Represent Group with SequenceId"</strong>. Using this method \r
- of hiding sequences, any edits performed on the visible group representative \r
- will be propogated to all the sequences in that group. <br>\r
- The hidden representative sequences will not be used in any\r
- calculations or web service alignments (<em>nb. this may change in\r
- the future</em>)\r
-</p>\r
-<p><strong><em>Hiding Columns</em></strong><br>\r
-To hide selected columns in an alignment, use the <strong>"View \r
- -> Hide -> Selected Columns"</strong> menu item, or right click within a region \r
- of selected columns in the scale above the alignment (only available in non \r
- wrapped mode) and select <strong>"Hide Columns"</strong>. </p>\r
-<p>When an alignment view contains hidden columns, certain constraints\r

+<p><strong><em>Hiding Sequences</em></strong><br>
+To hide selected sequences in an alignment, use the <strong>"View

+</ul>
+<p><strong>Column Separability</strong><br>Calculations where hidden columns are
+ excluded, and a single analysis performed on the result, are termed <em>column-separable</em>.
+ The simple Tree and PCA calculations are column separable because essentially the same results
+ would be obtained if the excluded hidden columns were replaced by gaps as the input to the calculation.</p>
+ <p>Multiple Sequence alignment and secondary structure prediction are both non-column-separable, and
+ so the exclusion of hidden regions leads to only 'locally optimal' results - sometimes
+ different to that obtained when using the full alignment.</p>
