Comment 16 for bug 334544

We have Ctrl+Q to quit the app,
Ctrl+W to close window and also Alt+F4 which closes windows.
Ctrl+S is Save on the other hand. If we use Super+S , Different accelerator but same letter would be a bit confusing.

We could use Super+Q which would be atleast a bit similar to quiting apps.
But, The menu has it named "Shut down" and in future to "Switch Off" , we might have users filing bugs & complaining that Super+S is better.

The best option would be Super+Q to bring up the drop-down [and in the future , once the menu is open shortcut "S" for the selecting Switch Off , "L" for Logout , "R" for Restart. probably "E" for Sleep or "P" if using E is confusing with expo]
