\placebookmarks [chapter,section]

That's true meaning that my minimal example was too minimal! Giving no argument works here is that the default, i.e. with no second argument to \placebookmarks, is to show the topmost level. But if you have chapters, sections, and subsections but want to show only chapter and section bookmarks, then \placebookmarks[chapter,section,subsection][chapter,section] should work but it shows all three levels. Here is a new minimal example showing the problem. With the [chapter,section] second argument, all three levels of bookmarks are shown; without the second argument, only the first level is shown. How do you show two levels? \setupinteraction[state=start] \setupinteractionscreen[option=bookmark] \placebookmarks [chapter,section,subsection] [chapter,section] \starttext \chapter{One} \section{One A} \input tufte \subsection{One A A} \input knuth \stoptext

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
