I wonder whether there's been any discussion about handling `C-g' during redisplay. For instance, if the user hits `C-g' six times in a row during redisplay, that should be an indication that perhaps Emacs should stop doing what it's doing -- and, for instance, switch on so-long-mode. Eli, would it be possible to implement something like that? -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
