+    Mousing over a conservation histogram reveals a tooltip which
+    contains a series of symbols corresponding to the physicochemical
+    properties that are conserved amongst the amino acids observed at
+    each position. In these tooltips, the presence of <em>!</em> implies
+    that the lack of a particular physicochemical property is conserved
+    (e.g. !proline).

 Conservation scores can be used to colour an alignment.  This is
 explained further in the help page for <a
