The major mode of a buffer is set by calling a function (e.g. the org-mode function for buffers that should be in org mode). That function does a million things to make sure that everything works properly: your setting a single variable does none of that and all you end up doing is confusing emacs. In most cases, you don't even call the mode function explicitly: it is called for you automatically, e.g. through the setting of auto-mode-alist. I have the following in my basic customizations: (add-to-list 'auto-mode-alist '("\\.org$" . org-mode)) That says to emacs: when find-file is called to open a file whose name ends in `.org' arrange to call the function org-mode on it. The function takes care of the setting of major-mode. Be sure to read Ch.23 of the emacs manual on major modes. Nick
