==References to an external file==
You can refer to referenced elements in an external file. MkIV requires for this the presence of the '''tuc-file''' of the referenced file. ConTeXt will catch the information to be included from this file.
===Example===
External files: hasseltbook.tex/pdf/'''tuc'''
The contents of hasseltbook.tex could be:
<texcode>
\starttext
\startstandardmakeup
\midaligned{\tfd Festivities in Hasselt}
\stopstandardmakeup
\startchapter[title=Euifeest,reference=euifeest]
Something about the Euifeest.\index{Euifeest}
\stopchapter
\stoptext
</texcode>
In your document you can say:
<texcode>
\setupinteraction
[state=start]
\useexternaldocument
[hia][hasseltbook][Festivities in Hasselt]
\setupinteraction
[state=start,
color=green,
style=bold]
\starttext
Most tourist attractions are described in \from[hia].\crlf
