-% *A problem:* 
+% *Your shorthands:*
+% \Anote etc. prevent editorial notes from appearing in the 
+% table of contents when such commands (\Anote etc., i.e.) 
+% appear in a heading (e.g.). But when you define a shorthand macro 
+% (using \newcommand) that has an optional parameter and \Anote 
+% or so in the defining code, something more is needed to have 
+% the lemma, without the note, in the table of contents (or ...) 
+% E.g., you might \newcommand*{\variant}[1][A]{\Anote{#2}{#1}}
+% so \variant{res} works like \Anote{res}{A} and \variant[B]{res}
+% works like \Anote{res}{B}. ednotes v1.22 offers two solutions 
+% to this problem: 
+% 1. You can precede your shorthand with \RobustTestOpt whenever it 
+%    appears in a "moving" argument like a chapter heading -- 
+%    \RobustTestOpt\variant{res}    as well as 
+%    \RobustTestOpt\variant[B]{res} , e.g. 
+% 2. You can save yourself from caring for \RobustTestOpt by using 
+%    \NewEdnotesCommand instead of \newcommand -- 
+%    \NewEdnotesCommand*{\variant}[2][A]{\Anote{#2}{#1}}
+% These facilities work only when the shorthand has an *optional* 
+% parameter and at least one *mandatory* parameter -- well, if it 
+% doesn't have, you can use \RobustTestOpt if you put a pair of 
+% braces after the shorthand macro name, this would work as well. 
+% 
+% *Known problems:*
