Correct. Updating the visible text for syntax HL is not that slow. The problem with folds is that also the text that is folded away must be inspected for syntax HL. It can still be slow if syntax HL has to resync after a closed fold. Depending on the settings it can mean al the folded lines have to be inspected for syntax HL. E.g. for C a /* inside a fold must be found to dedice if the lines below the fold are a comment. -- Warning label on a superhero Halloween costume: "Caution: Cape does not enable user to fly." /// Bram Moolenaar -- [email protected] -- http://www.Moolenaar.net \\\ /// sponsor Vim, vote for features -- http://www.Vim.org/sponsor/ \\\ \\\ download, build and distribute -- http://www.A-A-P.org /// \\\ help me help AIDS victims -- http://ICCF-Holland.org ///
