The spurious parentheses seem to be a side-effect of having unmatched curly brackets in the bit that I have quoted. The following eliminates them: \definemargindata [MyInMargin][inright] \definemarginframed[MyInMargin][topframe=on,bottomframe=on,rulethickness=1pt,width=1cm] \margintext{\blackrule[color=black, height=0.25ex, width=1cm]\\}\blackrule[color=black, height=0.25ex, width=7cm] \setupenumerations [ before={\blank[big]}, after={\blank[big]}, location=serried, width=broad, distance=0.5em, headstyle=bold, titlestyle=normal, way=bytext, conversion=numbers] \defineenumeration [theorem] [ text=Theorem, title=yes, style=italic, list=all, listtext={Theorem }] \starttext \margintext{2.1.1}{\starttheorem The square on the hypotenuse is equal to the sum of the squares on the other two sides. Ach is das schön, dass du da bist \stoptheorem } \stoptext I see also in this thread that you have sad "yes" to Aditya's suggestion. But that doesn't have the margintext. Do you still want/need margintext? — Bruce Horrocks Hampshire, UK — Bruce Horrocks Hampshire, UK
