Refer to the dedicated [To get bookmarks for chapters, sections, and subsections, use: <texcode>\placebookmarks[PDF Bookmarks and Headers]chapter,section,subsection] page.</texcode>
Added information on expansion of XML information for bookmarks
The {{cmd|setupinteraction}} command configures all interaction in the resulting PDF document. Basic interaction (meaning clickable links for references) is enabled using
</texcode>
This makes all links generated with the {{cmd|goto}} command (and indirectly the {{cmd|in}} and {{cmd|at}} commands) clickable. A page is dedicated to this system of '''[[References]]'''.

= PDF Bookmarks = == Quick start == For the impatient (like me), here is a complete example showing typical and Headers useful commands, which are explained below: <texcode>\setupinteraction[state=start] % don't forget this line!% make chapter, section bookmarks visible when opening document\placebookmarks[chapter,section,subsection][chapter,section]\setupinteractionscreen[option=bookmark]\starttext\startchapter[title=The beginning]Hi!\stopchapter\startchapter[title={A very, very\\long title}]Greetings!\startsection[title=Why so long]I don't know\startsubsection[title=Why not?]Good point.\stopsubsection\stopsection\stopchapter\startchapter[title=The never-ending story]Oh no.\stopchapter\startchapter[title=The never-ending story, bookmark=Forever!]Oh no.\stopchapter\stoptext</texcode> == Explanation == You need to activate the interaction handling in order to see the bookmarks using {{cmd|setupinteraction|[state=start]}}. <texcode>\setupinteraction [state=start]</texcode> The bookmarks window is usually not visible by default. To have the bookmark window open automatically when the document is opened: <texcode>\setupinteractionscreen [option=bookmark] </texcode> ''Disclaimer:'' {{cmd|setupinteraction}} works with Adobe Reader/Acrobat, but other PDF viewers behave differently. E.g. xpdf v3.01 always opens the bookmark window.
In the bookmark window, only chapter bookmarks are visible by default.
If chapter and section bookmarks should be visible:
<texcode>
\placebookmarks
[chapter,section,subsection]
[chapter]
</texcode>
This will open the document with the bookmarks for chapters and sections visible (read as: and open up the chapter bookmarks)
The [[Titles|unnumbered headings]] ({{cmd|title}}, {{cmd|subject}} etc.) do '''not''' create bookmarks, even when listed in {{cmd|placebookmarks}}.
In order to create the bookmarks, you need to add <code>force=yes</code>, for example like this:
<texcode>
\placebookmarks
[title, subject]
[force=yes]
</texcode>
If you do not like seeing the structure numbering in the bookmarks, you can add <code>number=no</code>, like this:
<texcode>
\placebookmarks
[chapter,section]
[chapter]
[number=no]
</texcode>
== Unwanted output ==
With a long heading in a huge font, you might want to add linebreaks by hand. No problem, just use <tt>\\</tt>. The bookmark code ignores <tt>\\</tt>, so the bookmark itself won't have a linebreak.
For example:
<texcode>
\setupinteraction[state=start]
\placebookmarks[chapter]
\setupinteractionscreen[option=bookmark]
\starttext
\startchapter[title=Long\\ title]
hello
\stopchapter
\stoptext
</texcode>
ConTeXt attempts to replace commands inside bookmarks with an acceptable string. However, the result is not always optimal. To tweak ConTeXts behaviour, add specific commands to {{cmd|simplifiedcommands}}.
For example, to replace the <code>\CONTEXT</code> logo (which would normally become ''CONTEXT'') with a camel-cased version, use the following:
<texcode>
\appendtoks
\def\CONTEXT{ConTeXt}
\to \simplifiedcommands
</texcode>
A more general method, also usable for the above problem, is to use the <code>bookmark</code> option to specify the bookmark text explicitly. For example:
<texcode>
\setupinteraction[state=start]
\placebookmarks[chapter]
\setupinteractionscreen[option=bookmark]
\starttext
\startchapter[title=A very long chapter\\ about splines,
bookmark=Splines]
hello
\stopchapter
\stoptext
</texcode>
{{mkii|In mkii, such manual bookmarks used the {{cmd|bookmark}} command on a separate line following a {{cmd|chapter}} command. With the new {{cmd|startchapter}} command, this is no longer needed, nor recommended.}}
== Private bookmarks ==
We can also place our own list of bookmarks:
<texcode>
\setupinteraction
[state=start]
\setupinteractionscreen
[option=bookmark]
\definelist
[mylist]
\placebookmarks
[chapter,mylist]
[chapter,mylist]
\starttext
\startchapter[title={My title}]
\input knuth\page
\bookmark[mylist]{Before input zapf}\input zapf
\stopchapter
\stoptext
</texcode>
== XML source ==
When processing XML input file information in TUC file is stored as the XML command with the reference to XML node
<texcode>
["titledata"]={
["label"]="section",
["title"]="\\xmlatt {xml:name::4}{title}"
</texcode>
You have to expand the information to get the text in TUC file and subsequently in bookmarks by modifying sections:
<texcode>
\setuphead
[section]
[expansion=yes]
</texcode>
= PDF Headers =
In order to add '''Author''', '''Title''', '''Keywords''', ... to PDF headers, use:
<texcode>
\setupinteraction
[state=start,
title={...},
author={...},
subtitle={...},
keyword={...}]
</texcode>
== Prevent certain characters from appearing in pdf headers ==
To ignore certain TeX commands in {{cmd|setupinteraction}} add them to {{cmd|simplifiedcommands}}. For example, to ignore {{cmd|quad}} in <code>pdfauthor</code>, use the following
<texcode>
\appendtoks
\let\quad\space
\to \simplifiedcommands
\setupinteraction
[author={Author1\quad Author2}]
</texcode>
{{mkii|Accented characters like ''ä'', ''č'', ... will turn into their unaccented counterparts ''a'', ''c'', ... by default. If you want to prevent that, use
<texcode>
\input spec-tst
</texcode>
For example
<texcode>
\enableregime[utf]
\setupinteraction
[state=start]
\setupinteractionscreen
[option=bookmark]
% before \placebookmarks
\input spec-tst.tex
\placebookmarks
[chapter,section,subsection]
[chapter]
... and here is your document with accented characters in titles & bookmarks ...
</texcode>}}
