This could be a bug report, but it is mostly a request for assistance. In https://www.pragma-ade.com/general/manuals/mathincontext-screen.pdf I see "2.11 Big operators" is at the very bottom of a page (no "content" of section 2.11 is on that page). This is an example of what I don't want, and anyone who feels the same way would consider this a (very minor) bug report for the (otherwise most excellent) math manual. For plain TeX, I have been using a macro I wrote called \need, so that a usage like \need 2cm would end the current page before omitting any more material, if there is less than 2cm left on the current page. I then used this in chapter and section macros (and anywhere else I felt like). I have played around a little bit with converting that macro for ConTeXt, but I'm not as confident that it Does The Right Thing in ConTeXt as for plain TeX. Q: is there a ConTeXt macro which does a \page if there is less space on the current page than specified by the argument to the macro? Thanks. Jim
