JIT lock is optimized for C-v and similar methods that page by large chunks of text rather than by one line.
I am not sure what that means, in concrete terms of Lisp program actions. I'm also not sure what you mean by "make text visible". It turns out that vertical-motion was fontifying all the text that it moved over. That seems to be easy to fix. _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
