Since Jalview 2.9, the Annotations file has also supported the definition of views on the alignment, and definition of hidden regions.</p>

+<!-- <p>
+ <em>VIEW_DEF</em> allows the current view to be named according to the
+ first argument after the tab character. If a second argument is
+ provided, then a new view is created with the given name, and
+ properties.
+ </p> -->
+ <p>
+ <em>VIEW_SETREF</em> takes either a single sequence ID string, or a
+ numeric index (second argument), and attempts to assign a
+ corresponding sequence as the <a href="../features/refsequence.html">reference
+ sequence</a> for the alignment.
+ </p>
+ <p>
+ <em>HIDE_INSERTIONS</em> takes a either a single sequence ID or a
+ numeric index, or no arguments. This command marks all gapped
+ positions in a specified sequence (either the one located by the
+ arguments, the current SEQUENCE_REF, or the reference sequence for the
+ view).

The interpretation of the COMBINE statement in <em>Version 2.8.1</em> was refined
so that only annotation line graphs with the given names ands the same
