-<p><strong>Split Frame Views</strong></p>
-<p/></p>Coding DNA (cDNA) and its protein product can be displayed in a split view, with cDNA above and protein below. The two alignments are
-linked, with these features supported:
-<ul>
-<li>mouseover or scrolling of either alignment is followed by the other (unless you turn off <strong><a href="../menus/alwview.html">"View→Automatic Scrolling"</a></strong>)</li>
-<li>on selecting rows, columns or regions in one alignment, the corresponding selection is made in the other</li>
-<li>sequence ordering in one alignment (using the cursor, or <strong><a href="../calculate/sorting.html">"Calculate→Sort")</a></strong> is also applied to the other</li>
-<li>editing (gap insertion / deletion) in the protein alignment is reflected in the cDNA (but not vice versa)</li>
-<li>on <strong><a href="../calculations/tree.html">"Calculate Tree"</a></strong> in either alignment, grouping, colouring and sorting by tree are applied to both</li>
-<li>the <strong><a href="../menus/alwformat.html">"Format→Font"</a></strong> menu option has an option 'Scale protein residues to codons'; select this option to make each protein residue
-the same width as a DNA codon (so the alignments 'line up' vertically)</li>
-<li>menu option <strong>"View→Protein"</strong> (in the cDNA panel) or <strong>"View→Nucleotide"</strong> (in the protein panel) allows you to show or hide the complementary alignment</li>
-<li>you can adjust panel heights by dragging the divider between them using the mouse</li>
-<li>menu options <a href="menus/alwview.html"><strong>"View→New View / Expand Views / Gather Views"</strong></a> behave as for a normal alignment window, but always create new views
-as split frames</li>
-</ul>
-<p>An alignment annotation row on the protein alignment shows the <strong><a href="../calculations/consensus.html">cDNA consensus</a></strong> for each peptide column.<br/>
-This consensus may reveal variation in nucleotides coding for conserved protein residues.</p>
-
-<p><strong>Opening a Split Frame View</strong></p>
-<p>A Split Frame View can be opened in one of the following ways:</p>
-<p><strong><em>Add Sequences</em></strong></p>
-<p>If you add (coding) DNA sequences to an open peptide alignment, or vice versa, <em>and</em> at least one DNA sequence translates to one of the
-peptide sequences, then the option to open in a split window is offered. The DNA may include start and/or stop codons, but no non-coding (intron)
-sequence.<br>
-If more than one cDNA variant is present in the alignment, Jalview will first try to match these to protein sequences based on any retrieved cross-references, and failing that, pairwise as they are ordered in the alignments.

+ <strong>Split Frame Views</strong>
+ </p>
+ <p>
+ Jalview provides a special viewing mode to show Coding DNA (cDNA)
+ and protein product alignments as a split view, with cDNA above and
+ protein below. The two alignments are linked, allowing editing and
+ analysis to be performed at both the peptide and nucleotide level.
+ Linked protein alignments also have an additional <strong>cDNA
+ Consensus</strong> annotation row, showing the distribution of codons at
+ each column of the protein alignment.
+ </p>
+ <p>
+ Split Frame views can be <a href="#opensplit">created in a
+ number of ways</a>. In the Jalview Desktop, Split Frame views are
+ saved in Jalview Projects, like any other alignment view.
+ </p>
+ <p>
+ <strong>Operations supported in Split Frame Mode</strong>
+ </p>
+ <p>Split Frame views allow the following:
+ <ul>
+ <li>Mouseover or scrolling of either alignment is followed by
+ the other (unless you turn off <strong><a
+ href="../menus/alwview.html">"View→Automatic
+ Scrolling"</a></strong>)
+ </li>
+ <li>On selecting rows, columns or regions in one alignment, the
+ corresponding selection is made in the other</li>
+ <li>Sequence ordering in one alignment (using the cursor, or <strong><a
+ href="../calculations/sorting.html">"Calculate→Sort")</a></strong>
+ is also applied to the other
+ </li>
+ <li>Editing (gap insertion / deletion) in the protein alignment
+ is reflected in the cDNA (but not vice versa)</li>
+ <li>Any trees imported or created with <strong><a
+ href="../calculations/tree.html">"Calculate Tree"</a></strong> on
+ one of the views allow both cDNA and Protein views to be grouped,
+ coloured or sorted.
+ </li>
+ <li>To allow for the different widths in cDNA and Protein
+ alignments, the <strong><a href="../menus/alwformat.html">"Format→Font"</a></strong>
+ menu option has an option 'Scale protein residues to codons'. This
+ option will make each protein residue the same width as a DNA
+ codon (so the alignments 'line up' vertically).</li>
+ <li><a name="mirror" />The 'Use same font for cDNA and peptide'
+ checkbox, when enabled, ensures that font or font-size changes in
+ either the cDNA or Protein alignment will also be mirrored. (<em>Added
+ in 2.10.2</em>)</li>
+ <li><strong>"View→Protein"</strong> (in the cDNA panel)
+ or <strong>"View→Nucleotide"</strong> (in the protein panel)
+ allows you to show or hide one or other of the linked alignment
+ panels.</li>
+ <li>Panel heights are adjusted dragging the divider between
+ them using the mouse</li>
+ <li><a href="../menus/alwview.html"><strong>"View→New
+ View / Expand Views / Gather Views"</strong></a> behave as for a normal
+ alignment window, but always create new views as Split Frames</li>
+ </ul>
+ <p>
+ An alignment annotation row on the protein alignment shows the <strong><a
+ href="../calculations/consensus.html">cDNA consensus</a></strong> for
+ each peptide column.<br /> This consensus may reveal variation in
+ nucleotides coding for conserved protein residues.
