The \about cross reference command woks ok if I use \about[aa]
It delivers the title (or part of it in this case) of the section marked aa.
but when I try to give it some text it blows up on the text, e.g., \about{foo}[aa]
So what if anything goes between the { and the }? What purpose do they serve?
\about does not support \about{...}[...] kind of references like \in or \at. Does some documentation say that this is supported? This is what core-ref.tex says \definecommand about {\dospecialabout} ... \unexpanded\def\dospecialabout[#1]% {...} This explains the error message that you get when you try \about{foo}[aa]. What do you want to achieve with \about{foo}[aa]? There may be some other way to do that. Aditya
