\placebookmarks [chapter,section,subsection] [chapter,section]
should work but it shows all three levels.
What do you expect, you open the chater *and* the section branches.
Thanks, now I understand what the second argument means: It's not "what levels are displayed" but is rather "what levels are opened (thereby showing the level below)". So, in order to show two levels (chapter and section): \placebookmarks [chapter,section,subsection] [chapter] I'll fix the wiki page. Too late: I just logged in to edit the page and saw that the new page has the clarificiation. Thanks, Taco! I edited the texshow-web entry for \placebookmarks. For the record, here's a complete example for showing chapter and section bookmarks: \setupinteraction[state=start] \setupinteractionscreen[option=bookmark] \placebookmarks [chapter,section,subsection] [chapter] \starttext \chapter{I} \section{I.A} \input tufte \subsection{I.A.1} \input knuth \subsubsection{I.A.1.a} Too deep for easy understanding! \section{I.B} \input tufte \stoptext
