-The structure viewer is launched from the sequence ID context
-menu. To view a particular structure associated with a sequence in the
-alignment, select the sequence and right click the mouse to open context
-menu {\sl Structure $\Rightarrow$ 3D Structure data $\Rightarrow$} opens a Structure Chooser dialog box.
-The second way is most useful if you want to view all structural data available for
-a set of sequences in an alignment. Select all the sequence ids in the sequence
-ID panel and right click the mouse to open context
-menu {\sl Structure $\Rightarrow$ 3D Structure data $\Rightarrow$}. If any of
-the {\bf currently selected} sequences have structures associated they will
-appear in the Structure Chooser dialog box. The structures can be ranked by
-different parameters, 'Best Quality' is defaul option. Select the
-structures required and click {\sl View} to open a structure viewer containing
-the associated structures superposed according to the alignment.

+\label{structurechooser}
+The structure viewer is launched via the Sequence ID context
+menu. To view structures associated with a sequence or a selected set of
+sequences in the alignment, simply right click the mouse to open the context
+menu, and select {\sl 3D Structure data \ldots} to open the Structure Chooser
+dialog box.
+
+If any of
+the {\bf currently selected} sequences have structures in the PDB,
+they will appear in the Structure Chooser dialog box. The structures can be ranked by
+different parameters, but are by default ordered according to their PDB
+quality score.
+
+To view one or more structures, simply click {\sl
+View} to open a structure viewer containing the structures selected in the
+dialog. If several structures were picked, these will be shown
+superposed according to the alignment.
+You may find Jalview has already picked the best structure - using one of the
+criteria shown in the dropdown menu (e.g. 'Best Quality', which is picked by
+default). However, you are free to select your own.
