What is more difficult is to handle various kinds of data (i.e. multiple major modes) in a single buffer. > If it is feasible, could this feature be considered for implementation > in a future Emacs version? The underlying functionality needed for that has existed in Emacs "for ever", so no need for a future Emacs. Someone just needs to implement it and make it available as a package. Stefan
