Hi, You can define a custom command for the chapter, where the first argument (i.e, the number) is 'ignored' – \define[2]\ChapterTitle{#2} \setuphead[chapter][command=\ChapterTitle] It will still appeared as numbered in any lists (ToC, etc). Also, it can be accessed using \headnumber[...][...]. An example graphic – \startuseMPgraphic {graphic:chapter} picture cg; cg := outlinetext.d ("\ssbfd \headnumber[chapter]") (withcolor transparent(1,0.5,blue)); fill boundingcircle cg withcolor transparent(1, 0.5, lightgray); draw cg; \stopuseMPgraphic Using \headnumber[..][..] any 'conversion' applied to the chapter number (romannumerals, words, etc) are also preserved.
