I’ve already figured out how to refer to pages (using “\at[REFERENCE]”), but how is this done with chapters? I’m apparently too simple-minded to understand the manual (and I don’t understand the differences between \reference, \textreference, \in, \about).

When you use \chapter:

\starttext

\chapter[sec:knuth]{Knuth}

\samplefile{knuth}

See \in{chapter}[sec:zapf] at \at{page}[sec:zapf].

\chapter[sec:zapf]{Zapf}

\samplefile{zapf}

See \in{chapter}[sec:knuth] at \at{page}[sec:knuth].

\stoptext

When you use \startchapter:

\starttext

\startchapter[title={Knuth},reference={sec:knuth}]

\samplefile{knuth}

See \in{chapter}[sec:zapf] at \at{page}[sec:zapf].

\stopchapter

\startchapter[title={Zapf},reference={sec:zapf}]

\samplefile{zapf}

See \in{chapter}[sec:knuth] at \at{page}[sec:knuth].

\stopchapter

\stoptext
