Hi all, it is quite easy to have chapters in headers and footers as shows this example. \setuppagenumbering[location=] \setupheadertexts [text] [chapter] [] [] [chapter] \setupinteraction [title={foo}, subtitle={bar}, author={Peter}, keyword={context}] \starttext \startchapter[title={chapter title},] \input lorem \stopchapter \startchapter[title={another chapter title},] \input lorem \stopchapter \stoptext How can I insert title, subtitle and author from setupinteraction into headertexts? Background: authors shall define title, subtitle etc in the product file with setupinteraction (or a better method if available). In the environment file I want to insert theses informations into headers and footers. TIA juh
