A few weeks back I've asked here about the structure of titles, as the PDF bookmarks didn't work for me. I was given a solution, which should work, but unfortunately it doesn't. I don't know if this is a bug or is this expected behaviour. For the file: \setupinteraction[state=start] \placebookmarks[part,chapter,section] \setupinteractionscreen[option=bookmark] \starttext \placecontent \startfrontmatter \startchapter[title=Prologue] \input knuth \stopchapter \stopfrontmatter \startpart[title={Part A}] \startchapter[title=One] \input knuth \stopchapter \stoppart \startbackmatter \startchapter[title=Epilogue] \input knuth \stopchapter \stopbackmatter \stoptext ConTeXt (Mk IV) generates a PDF file which has only one item in the bookmarks -- the Prologue. The other chapters show up only if the file is changed with \placebookmarks[chapter,section] but then of course there is no sign of Part A in the bookmarks. I would expect the bookmarks to look like this: Prologue Part A One Epilogue Regards Michał
