For example, do all text modes use a keymap that inherits from text-mode-map or a syntax table that inherits from text-mode-syntax-table? I suspect not, so I'm thinking of using something like: (defun major-mode-type () (let ((lisp-directory (expand-file-name "../lisp" data-directory)) (mode-directory (directory-file-name (file-name-directory (symbol-file major-mode 'defun))))) (and (not (equal lisp-directory mode-directory)) (file-relative-name mode-directory lisp-directory)))) which e.g. returns nil for dired-mode and Info-mode, "textmodes" for text-mode and sgml-mode, and "progmodes" for java-mode and sql-mode. -- Kevin
