 @subsection Use of the @code{interpreter} Property
 
 All text objects---such as titles, labels, legends, and text---include
-the property @qcode{"interpreter"}, this property determines the manner in

+the property @qcode{"interpreter"} that determines the manner in
+which special control sequences in the text are rendered.
+
+The interpreter property can take three values: @qcode{"none"}, @qcode{"tex"},
+@qcode{"latex"}.  If the interpreter is set to @qcode{"none"} then no special
+rendering occurs---the displayed text is a verbatim copy of the specified text.
+Currently, the @qcode{"latex"} interpreter is not implemented and is equivalent
+to @qcode{"none"}.
 
 The @qcode{"tex"} option implements a subset of @TeX{} functionality when
 rendering text.  This allows the insertion of special glyphs such as Greek
-characters or mathematical symbols.  The special characters are inserted with
-a code following a backslash (\) character, as in the table
-@ref{tab:extended}.

+toolkit renders @TeX{} instructions.
