Hello, I am having difficulties with the use of unnumbered chapters (\title) as well as the use of appendices. http://wiki.contextgarden.net/Titles#Unnumbered_titles_in_table_of_contents gives a few recipes for the use of unnumbered titles and their inclusion in the table of contents. Unfortunately, they do not work! \definehead [intro] [chapter] \setuphead [intro] [number=no] will increment the chapter number, as does \setuphead [title] [incrementnumber=yes,number=no] trying "coupling=no" gives missing number errors (in the toc). Furthermore, placing chapters into \frontmatter and \backmatter might not always be a solution. In a document structured in *parts*, one might want to have an introduction (and other "front matter") as well as conclusions (and other "back matter"). One needs a means of switching section blocks, for example, without resetting everything. Maybe this can become an option in \startfrontmatter [reset=no] \startappendices [reset=no] \startbackmatter [reset=no] for example, or else: \setupsectionblock [appendix] [resetnumber=no] % number=yes|no Another route could be through the use of the *mysterious* structureresetset \definestructureresetset [default] [0,0] [1] % do not reset parts and chapters \setuphead [part,chapter] [sectionresetset=default] coupled somehow to the section blocks.
