+<p>This sets the visual display properties according to the given values for all the annotation rows with labels matching <em>Row label</em>. The properties mostly affect the display of multi-character column labels, and are as follows:
+<ul><li><em>centrelabs</em> Centre each label on its column.</li>
+<li><em>showalllabs</em> Show every column label rather than only the first of a run of identical labels (setting this to true can have a drastic effect on secondary structure rows).</li>
+<li><em>scaletofit</em> Shrink each label's font size so that the label fits within the column. Useful when annotating an alignment with a specific column numbering system.</li>
