-If you have |'conceallevel'| set to 1 and if your encoding is utf-8, then a
-number of character sequences will be translated (ie. better visualized) using
-|syn-cchar|, including various accented characters, Greek characters in

+If you have |'conceallevel'| set to 2 and if your encoding is utf-8, then a
+number of character sequences can be translated into appropriate utf-8 glyphs,
+including various accented characters, Greek characters in MathZones, and
+superscripts and subscripts in MathZones.  Not all characters can be made into
+superscripts or subscripts; the constraint is due to what utf-8 supports.
+In fact, only a few characters are supported as subscripts.
+
+One way to use this is to have vertically split windows (see |CTRL-W_v|); one
+with |'conceallevel'| at 0 and the other at 2; and both using |'scrollbind'|.
