Hans, I’m afraid that PDF bookmarks don’t follow sectionconversionset option from \setuphead.
Here is the sample: \setupinteraction[state=start] \placebookmarks[chapter,section] \definestructureconversionset[sectionnumbers][0,I,A,n,g][n] \definestructureconversionset[appendix:sectionnumbers][0,A,n,g,a][n] \setupheads[sectionconversionset=sectionnumbers] \starttext \startbodymatter \chapter{Chapter in bodymatter} \section{Section in bodymatter} \stopbodymatter \startappendices \chapter{Chapter in appendices} \section{Section in appendices} \stopappendices \stoptext Many thanks for your help, Pablo -- http://www.ousia.tk ___________________________________________________________________________________ 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 ___________________________________________________________________________________
