\setuplabeltext [chapter=Chapter ] enables a label in chapter headings. Sometimes, one wants to have an unnumbered chapter-level structure that otherwise appears in the table of contents, bookmarks, marking, etc. without having to make many special definitions. One suggests: \definehead [NOchapter] [chapter] \setuphead [NOchapter] [incrementnumber=no,number=no,bodypartlabel=] \starttext \startNOchapter [title=Introduction] \stopNOchapter \startchapter [title=First chapter] \stopchapter \stoptext And then adding NOchapter to the contents combined list, to the bookmarks, and so on, not to speak about marking. Ugh! Much easier would be the occasional use of \startchapter [title=Introduction,incrementnumber=no,number=no,bodypartlabel=] \stopchapter but this does not work! One gets: "Chapter Introduction". That this does not work I suppose might be somewhat of a bug... Even better, more coherent, more logical, would be \startchapter [title=Introduction,incrementnumber=no,number=no,label=no] \stopchapter (Note that "label=no" is used for lists). This would also have the advantage of allowing the chapter labeltext to be defined for each language, rather than be empty, so that it could then be simply turned on or off. In fact, label=no would be the default setup. Alan
