The {{cmd|setupinteraction}} command configures all interaction in the resulting PDF document. Basic interaction (meaning clickable links for references) is enabled using
<texcode>
\setupinteraction[state=start]
</texcode>
This makes all links generated with the {{cmd|goto}} command (and indirectly the {{cmd|in}} and {{cmd|at}} commands) clickable.
== Hints ==
=== Link coloring ===
By default, the link text gets a green or red [[Color|color]], depending on whether the link is to another page or to the same page. You can change the link colors with the <tt>color</tt> (links to other pages) and <tt>contrastcolor</tt> (links to the same page) properties. For example, to disable link coloring alltogether:
<texcode>
\setupinteraction[state=start,color=,contrastcolor=]
</texcode>
=== Clickable table of contents ===
To make table of contents items clickable, use the {{cmd|setupcombinedlist}} command.
<texcode>
\setupcombinedlist[content][interaction=all]
</texcode>
This makes the entire table of contents line clickable. It is possible to select just one part (<tt>sectionnumber</tt>, <tt>pagenumber</tt>, <tt>text</tt>).
If links have a color, this will also make the table of contents get a different text color. You can use the <tt>color</tt> property to change it back, <i>e.g.</i>:
<texcode>
\setupcombinedlist[content][interaction=all,color=black]
</texcode>
Alternatively, you can use the <tt>textcolor</tt> property to change just the text colour, and leave the section and page numbers colored.
=== Default focus mode ===
By default, clicking an inter-document hyperlink will switch to "fit page" mode, to override this:
<texcode>
\setupinteraction[state=start,focus=standard]
</texcode>
