How to set section title based on section content? I have a document that has some structures like this: \starttext \startsection[title={Animals}] \event{\input knuth } \stopsection \startsection[title={Books}] \event{\input knuth } \stopsection \stoptext The event macro runs a bunch of conditionals, deciding which content to place inside the section. It places any one of neary 200 possible different types of content there. Sadly when I wrote the code, I thought generic titles would be okay. Now I realize I need to be more specific, giving titles that match the content inside. I could move the section titles inside the \event macro, but it means rewriting ~200 other macros. In other words, how do I define a section title by defining it somewhere in the content of the \event macro? \starttext \startsection[\whatistitle] %<-- would display "Neon Tetras" \event{\thetitleis{Neon Tetras}\input knuth } \stopsection \startsection[\whatistitle] %<-- would display "Detective Stories" \event{\thetitleis{Detective Stories}\input knuth } \stopsection \stoptext
