Hi,

Can you please tell me how can I add file extension '*.mm' to use
c/c++ font lock mode?

Thank you.

There is a variable auto-mode-alist which associates file name patterns
with modes. You can read about it with C-h v auto-mode-alist[RET]
(that is: control-h, then "v" -- you are then queried for a var name in
the minbuffer; enter "auto-mode-alist").

To set it from your start-up file, you may use this code there:

  (add-to-list 'auto-mode-alist '("\\.mm\\'" . c++-mode))
