Hello, From command/setuphead http://wiki.contextgarden.net/Command/setuphead I inferred this should work to set linespace to 1.5 within the chapter/section but it doesn't. Should it? I read on \setupinterlinespace and it's resetting mechanic but thought the parameter in setuphead would work. Also, I checked and this parameter is not mentioned in the manual, so maybe it does not exist. \setuphead[chapter][interlinespace=big] \starttext \chapter{Some title} Lines with 1.5 space? \input tufte \startchapter[title={Some title}] Try again? \input tufte \stopchapter \startchapter[title={Some title}] \setupinterlinespace[big] Now it works. \input tufte \stopchapter \startchapter[title={Some title}] But it "leaks" out of the previous start-stopchapter. \input tufte \stopchapter \stoptext Thank you for your attention, YT
