Hi,
 
maybe, codes is our language :-)
 
% define a new head
\definehead[backmatterchapter][chapter]

\starttext
\startfrontmatter
\title{Preface}
\completecontent
\stopfrontmatter

\startbodymatter
\chapter{First Chapter}
\stopbodymatter

\startbackmatter
\backmatterchapter{Backmatter}
\stopbackmatter
\stoptext
 
The chapter title "Backmatter" in the backmatter won't appear in the Contents. Why? How can I make it appear in the Contents?
 
Best regards,
Tim
