Re: Shortcut to shutdown menu
In older versions the command was (I think) gnome-session-save.
In 11.10 you can press alt + F2 and enter
Inside it there should be a line that begins with Exec=
Copy/Paste the command that follows (/usr/lib/indicator-session/gtk-logout-helper --shutdown) in an alt + F2 dialog and press <enter> and see what happens. I'm not logged in to Ubuntu now so I can't test to see if it will work.
If it does the trick you can go to Keyboard shortcuts and create a new mapping.
