Hans, sorry for the long message, but I’m afraid that bookmarks have some issues. 1. When specifying sectionblocks, bookmarks for parts don’t contain chapters as child elements: \setupinteraction[state=start] \placebookmarks[part, chapter][part, chapter] \setuphead[part][placehead=yes] \starttext \startfrontmatter \chapter{Foreword} \chapter{Introduction} \stopfrontmatter \startbodymatter \part{First Part} \chapter{First Chapter} \chapter{Second Chapter} \part{Second Part} \chapter{Third Chapter} \chapter{Fourth Chapter} \stopbodymatter \stoptext It isn’t related to parts and chapters, it also happens with chapters and sections: \setupinteraction[state=start] \placebookmarks[chapter, section][chapter, section] \starttext \startfrontmatter \section{Foreword} \section{Introduction} \stopfrontmatter \startbodymatter \chapter{First chapter} \section{First section} \section{Second section} \chapter{Second chapter} \section{Third section} \section{Fourth section} \stopbodymatter \stoptext It works fine, if sectionblocks are removed: \setupinteraction[state=start] \placebookmarks[part, chapter][part, chapter] \setuphead[part][placehead=yes] \starttext \chapter{Foreword} \chapter{Introduction} \part{First Part} \chapter{First Chapter} \chapter{Second Chapter} \part{Second Part} \chapter{Third Chapter} \chapter{Fourth Chapter} \stoptext 2. Sectionblocks also displace bookmark location, such as in this sample: \setupinteraction[state=start] \placebookmarks[part, chapter, hiddentitle][part, chapter] \setuphead[part][placehead=yes] \definehead [hiddentitle] [chapter] \setuphead [hiddentitle] [number=no] \starttext \hiddentitle{[Copyright]} \startfrontmatter \chapter{Foreword} \chapter{Introduction} \stopfrontmatter \startbodymatter \part{First Part} \chapter{First Chapter} \chapter{Second Chapter} \part{Second Part} \chapter{Third Chapter} \chapter{Fourth Chapter} \stopbodymatter \stoptext Foreword and Introduction are listed after Fourth Chapter. If sectionblocks are removed, bookmark listing is ordered right: \setupinteraction[state=start] \placebookmarks[part, chapter, hiddentitle][part, chapter] \setuphead[part][placehead=yes] \definehead [hiddentitle] [chapter] \setuphead [hiddentitle] [number=no] \starttext \hiddentitle{[Copyright]} \chapter{Foreword} \chapter{Introduction} \part{First Part} \chapter{First Chapter} \chapter{Second Chapter} \part{Second Part} \chapter{Third Chapter} \chapter{Fourth Chapter} \stoptext 3. In the previous sample, as well in the following one, bookmark hierarchy is wrong: \setupinteraction[state=start] \placebookmarks[part, chapter, hiddentitle][part, chapter] \setuphead[part][placehead=yes] \definehead [hiddentitle] [chapter] \setuphead [hiddentitle] [number=no] \starttext \hiddentitle{[Copyright]} \startfrontmatter \chapter{Foreword} \chapter{Introduction} \stopfrontmatter \startbodymatter \part{First Part} \chapter{First Chapter} \chapter{Second Chapter} \part{Second Part} \chapter{Third Chapter} \chapter{Fourth Chapter} \stopbodymatter \startbackmatter \chapter{Conclusions} \chapter{Epilogue} \stopbackmatter \stoptext I’m afraid that (the misplaced Foreword or Introduction and) Conclusions and Epilogue should be first-level bookmarks (such as Copyright is). After a sectionblock, chapters should have first-level bookmarks if there is no part bookmark containing them. Otherwise, this will be the misleading impression that the chapters are children of the part bookmark. Am I missing something or have I hit a bug?
