I was hoping you'd say that. :) NSMenuItem already has built-in support for this. What you need to do is create two separate menu items and mark them as being alternates of each other (this can be done in IB or with -[NSMenuItem setAlternate:]). One menu item's modifiers should include the option key and the other should not. The menu system will then automatically display the correct menu item depending on whether the user is pressing the option key.
