You got a legal point there, but Ctrl+Alt+End will do it for you nicely.
Not being able to navigate to the shutdown button with keyboard is not a good thing at all, but this functionality is provided in other means:
Logout button: Ctrl+Alt+Del
Shutdown Button: Ctrl+Alt+End
Lock Screen Button: Ctrl+Alt+L
Mint 17 has a new feature which I believe is exactly what you are looking for. You can access the shutdown options with Ctrl-Alt-End
Make the shortcut yourself.
It is probably a bad idea to have this as a default shortcut though.
How to make a shortcut? Check the documentation for your Desktop Environment or turn to Forums (where this discussion belongs anyway)
