A practical application is if I have been using the built-in elisp mode for .el files and then implement xah-elisp-mode, even if I code (add-to-list 'auto-mode-alist '("\\.el$" . xah-elisp-mode)) in my init.el, the previously visited buffers that are automatically opened when I start emacs will still be in elisp-mode. The fix, of course is to invoke xah-elisp-mode from the minibuffer. This is certainly doable, even with multiple elisp buffers opened, but I'm always looking to eliminate redundancies. It would be handy if there were a command that would set all visited buffers ending in a specific file extension to a specific mode. If such were available, it would come in handy for experimenting with alternative major modes. Is there such a feature? Thanks -- Tim tj49.com
