You need \setuphead[chapter][ownnumber=yes] only when you want to use the \chapter command but not when you use \startchapter.8. Oktober 2015 um 12:13The reference manual explains that one can set individual numbers on a chapter:
\setuphead[subsection][ownnumber=yes]
\subsection{399}{The old number}
So I tried \setuphead[chapter][ownnumber=yes] but then I am in the dark how to use this.
The reference manual (september 2013 -- latest?) was of no help because it does treat \chapter but not yet explains \startchapter. Neither did the ConTeXt Commands (July 2015 version) offer me I clue.
I tried \startchapter[number=6] but this doesn't work.
How to?
