Hello Everybody, I need to increase my header's space temporarily and according to pg 99 of context_an_excursion "\startlocal ... \stoplocal" is the way to go - unfortunately my LMTX (2021.02.02 15:49) disagrees: \setuppapersize[A4][A4] \setuplayout[ ... header=15mm, ... ] \starttext \input tufte \page \startlocal \setuplayout[header+=20mm] \input tufte \stoplocal \page \input tufte \stoptext This fails: tex error > tex error on line XX in file ./local-layout.tex: Undefined control sequence XX >> \startlocal Do I need to load something in order to use this? Or has it been completely removed? And if so, is there a new alternative method to do the same thing? I was unable to find anything on this topic except https://www.mail-archive.com/ntg-context@ntg.nl/msg63602.html which raises the same question already in 2012 but never answers it IMHO. Thank you very much, Werner
