How can one make the page with the TOC also
appear in the bookmarks using mkiv?
\setupinteraction[state=start]
\placebookmarks[title,chapter][force=yes]
\starttext
% Variant 1, shows the text which is set with
\setupheadtext[<language>][content=...]
\completecontent
% Variant 2, you can set your own text for the bookmark
% \starttitle[title=\headtext{content},reference=content,bookmark=Table
of content]
% \placecontent
% \stoptitle
