In principle, there is only one overlay-arrow-position variable, and since its value is a marker, its value includes the buffer in which it occurs.
This is how e.g. gdb can easily move the overlay arrow between buffers -- just modify the global variable. gdb could use a *gud* buffer local variable. That way multiple instances of gud wouldn't steal the arrow from eachother. _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
