Alt Car in Emacs for OSX

When I installed emacs for OSX, right option key acted as Meta instead of my beloved alt-car. It can be fixed using these steps:

1. If you use emacs 23 or prior, install package.el

2. Add marmalade to the list of repositories in your .emacs:

   ```lisp
   ;; Adds marmalade to package.el
   (require 'package)
   (add-to-list 'package-archives '("marmalade" . "http://marmalade-repo.org/packages/"))
   (package-initialize)
   ```
   

3. Refresh your package index using M-x package-refresh-contents

4. Install mac-key-mode using M-x package-install mac-key-mode

5. Configure the right option key to act like alt-car using the following lines in your .emacs: (require ‘mac-key-mode) (setq mac-option-key-is-meta t) (setq mac-right-option-modifier nil)

6. Restart emacs

You should now be able to use the right option key as alt-car to enjoy characters like @ and } on a french canadian keyboard.
