Hi Hans (probably the only relevant recipient), while Patrick Gundlach could provide me a solution for all chapters in one file there still is no idea how to do it within the project structure. See for example the following: The generated empty pages after the TOC (page 2), and after the last chapter (14 and 15) all have pagenumbers. Quite ugly. How to get rid of them? How to make empty pages by default empty? Steffen Minimal Example: \definepagebreak [chapter] [yes,header,right] \setuphead [chapter] [page=chapter, ] \setuppagenumbering[alternative=doublesided] \setupsectionblock[frontmatter][page=chapter] % doesn't work \starttext \startfrontmatter \completecontent \stopfrontmatter \startbodymatter \chapter {test} \dorecurse{10}{\input tufte } \chapter {test} \dorecurse{10}{\input tufte } \chapter {test} \dorecurse{10}{\input tufte } \stopbodymatter \stoptext
