As I wrote earlier, the feature I have in mind should not be an additional (minor or major) mode, but a core feature, adding the possibility for Emacs users to open multiple files in a single buffer, in a way that would be as transparent as possible to everything else. Or, in other words, to work on a list of buffers as if it were a single buffer. Otherwise it would indeed be necessary to reimplement many (possibly all) commands, and other problem would have to be resolved, with a result that would likely be too inefficient. My question was: Is this feasible, or is the one-to-one correspondence between buffers and files too deeply rooted in Emacs' codebase that it is not feasible? If it is feasible, could this feature be considered for implementation in a future Emacs version? Gregory
