Is > there any practical use for text which is invisible but not > intangible? Invisible but tangible appealed to me for handling Rmail ignorable headers using inbox format. On the one hand I wanted to make these headers invisible to the User but on the other hand I want to add/remove text behind the scenes, so to speak, to the headers to handle attributes and labels. I can imagine that cursor movement might get kind of weird around invisible but tangible text. There are three or four other ways to solve the problem, each with its own set of tradeoffs. Invisible implying intangible also makes for a useful solution. My gut feel is that having the three choices of invisible, intangible and hidden (which is both invisible and intangible) is the best solution. I'd also want to have a variable for each case like buffer-invisibility-spec, e.g. buffer-intangible-spec and buffer-hidden-spec. -pmr _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://mail.gnu.org/mailman/listinfo/emacs-devel
