Thanks I did not know the correct designations for the various parts of the captionlabel: the prefixconnector and the numberstopper. It is clear now.

Oktober 2016 um 10:39 prefixconnector is the separator between the section number (=prefix) and the float number (=figure number), the symbol at the end of the float number is called numberstopper. In your example you don’t have a section which can act as prefix number no did you change which prefixes should be shown (by default only chapters are used as prefix). The suffix key you use (together with suffixconnector and suffixstopper) is used to show the number for subfigures, e.g. figure 3.a. Here is a working example for the use of the prefixconnector key. \starttext \section{This is a section} \setupcaptions[prefixsegments=section,prefixconnector=-] \startplacefigure[title=\tex{setupcaptions[prefixconnector=-]}] \externalfigure[dummy][width=.5\textwidth] \stopplacefigure \stoptext Wolfgang ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
