Is it possible to shutdown or restart a Logitech Revue without pulling the power cord? My Revue (Android 3.1) was acting balky, so I wanted to restart it.  I spent several minutes looking through menus, but didn't find an option to shut down or restart the OS.   I ended up pulling the power cord, but it seemed a bit harsh.
Google's support page provides this option:


  To Reboot your Google TV:
  
  To reboot your Sony TV or Bluray player or your Logitech Revue, press
  Control + Alt + Backspace on your controller.


If you had adb connected you could also try adb reboot, which works on other devices.
