Or is there some more foolproof way of getting those headers into the right place?

Here is something I quickly wrote up: First, define some labels for the columns of the ToC — \definesynonyms[toclabel][toclabel][\TOCLabel] \setupsynonyms[toclabel][textstyle=\sc] \toclabel{TOCNumberLabel}{Chapter} \toclabel{TOCTitleLabel}{Title} \toclabel{TOCPageLabel}{Page} Then compute the width of the chapter-number and page-number labels \setwidthof\TOCLabel{TOCNumberLabel}\to\TOCNumberLabelWidth \setwidthof\TOCLabel{TOCPageLabel}\to\TOCPageLabelWidth and define a 'paragraphs' block with 3 columns with a separation of 1em between each column \defineparagraphs [TOCpar] [n=3] \setupparagraphs [TOCpar] [each] [distance=1em] Set the width of the first column to the width of the label (and center chapter number) \setupparagraphs [TOCpar] [1] [width=\dimexpr\TOCNumberLabelWidth, align=middle] and similarly for the third column (and center the page number) \setupparagraphs [TOCpar] [3] [width=\dimexpr\TOCPageLabelWidth, align=middle] Finally, wrap it all up in the macro \define[3]\TOCEntry{% \startTOC #1 \TOCpar #2 \TOCpar #3% \stopTOC% } and indicate the command to use in the setup \setuplist [chapter] [alternative=interactive, command=\TOCEntry, after=\endgraf] % required The ToC along with column labels is placed with \TOCLabel{TOCNumberLabel}% \hfill\TOCLabel{TOCTitleLabel}\hfill% \TOCLabel{TOCPageLabel} \placecontent Of course, you can choose to not set the 'align' keys in \setupparagraphs[TOC] if center alignment is not required/desired. Hope this helps. Best, kauśika
