Dear List, After once more a little changes this is the example I wanted, and it is perfekt: \definemargindata [MyInMargin][inright] \definemarginframed[MyInMargin][topframe=on,bottomframe=on,rulethickness=1pt,width=1cm] \defineenumeration [theorem] [ text=Theorem, title=yes, width=fit, distance=0.5em, alternative=serried, ] \margintext{\blackrule[color=black, height=0.25ex, width=1cm]\\}\blackrule[color=black, height=0.25ex, width=15cm] \starttext \margintext {1.1.1} \starttheorem The square on the hypotenuse is equal to the sum of the squares on the other two sides. \stoptheorem \stoptext Many thanks to Bruce and Aditya for your help.

Ach is das > schön, dass du da bist} \stoptheorem 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 ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___________________________________________________________________________________ ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://mailman.ntg.nl/mailman3/lists/ntg-context.ntg.nl webpage : https://www.pragma-ade.nl / https://context.aanhet.net (mirror) archive : https://github.com/contextgarden/context wiki : https://wiki.contextgarden.net ___________________________________________________________________________________
