This is code that runs anytime you find (open) a file. In this case, you want to check and see if the file you've found ends with .cu, and if so, to use cc-mode. This function will do that: (defun my-find-file-hook() (let ((fn (buffer-file-name))) (when (string-match "\\.cu$" fn) (cc-mode)))) You have to tell Emacs to run this function every time you open a new file, so you add the hook: (add-hook 'find-file-hooks 'my-find-file-hook) Put both forms in your .emacs, and the next time you open emacs you'll be all ready to go. (you can also load them into a running emacs using C-x C-e to execute the previous command in a lisp-mode buffer, such as scratch or .emacs). HTH, Tyler
