[Tails-dev] Shortcut to Start Orca

Hi,

After a long time away from Tails, I would like to set up a virtual
machine with tails to make some tests to contribute more.
In the documentation, I read it is now possible to start Orca with
Alt+Super+S.
Unfortunately, it doesn't seem to work in greater. I though it worked...
When this shortcut works?
Do I make a mistake with the "super" key? Is not it the Windows key?

Thanks,

Patrick
