Yes, that’s correct. I guess command= attribute kind of replaces the “default” processing for the head ? Because when I use it the “align = center” does not seem to be taken in account. Thanks a lot Joseph Sent from Windows Mail From: Thomas A. Schmitz Sent: Sunday, October 25, 2015 5:32 PM To: ntg-context@ntg.nl Is that what you're looking for? \define[2]\MyChapterTitle% {#2: #1} \setuphead[chapter] [command=\MyChapterTitle] \starttext \startchapter [title=Some Title] Some text. \stoptext When you define a command, #1 is your chapter/section/whatever number, #2 is your title. (For future reference: please make minimal examples when asking a question.)
