I think that mac's Help menu is also an example of great UX. If you don't know where 'copy' is, just click on the Help menu and start typing 'cop..' and you'll be presented with a beautiful animation (sort of) that shows you exactly where that command is. The great thing about it is that it's system-wide and works in every single application (and for those who don't know: the key shortcut is Command+Shift+/, you can use it as a menu-item launcher!)
