I would like to use Super+E as a shortcut to open Nautilus. Whenever I add Super+E as a shortcut in System Settings > Keyboard > Shortcuts it works fine. But after I reboot/re-log Super+E does not work anymore. On the other hand, the shortcut is still correctly listed in Keyboard > Shortcuts.
I've already tried CompizConfig Manager and configured a new command for starting Nautilus, but this seems to be buggy: Nautilus will always open behind the current active window.
