I am setting up a ConTeXt document that requires a very particular style for the footers. I need the first and last
\subjects followed by the page number in the right corner of the page, like so:
Subject A - Subject C - 9
The purpose is similar to how a dictionary's pages are marked, with the first and last words on that page listed in the top corner, so it's easy to skip to the correct page.
I'm currently trying to make
\setupfootertexts work for me. There are two problems I'm running into.
subject key only appears to work if it is the sole argument to one of the parameters of
\setupfootertexts, which is preventing me from putting even one subject name in the same corner as the page number. The documentation for how to use this is nearly non-existent, even in the newest revision of the manual, only mentioning that they can be used but not addressing this problem.
Second, I haven't a clue how to collect the necessary
subject headings from the page and process them into a form that can be injected into the footer. I looked at registers, but the output of
\placeregister appears to be too special-purpose for this use.
