Suppose that in an interactive document, I would like to have a local table of contents (e.g. \placelist[section]) on each page, but I would like the current portion (e.g. section) to be highlighted in some way, perhaps by style or color, within the list. What mechanisms are needed to achieve this?
I can envision doing it by somehow extracting mark information and list information into control sequences and comparing them with \ifx. However, I usually find that whatever I want to do, ConTeXt already has a way of doing! -- Miller Maley
