I'm using Ubuntu 15.10. I'm looking for a shortkey to "Navigate to the desktop". I saw that in previous versions of Ubuntu Ctrl + Alt + D works - but it doesn't work for me in 15.10.
Do you know what the shortkey is for 15.10?
I found it. It should be Ctrl+Super+D.
You can see it under System Settings → Keyboard → Shortcuts → Navigation → Hide All Normal Windows
Super + D should work.
If this doesn't there is something wrong with your machine - have you reassigned any shortcuts?
super
key` for few second, you can see the list most important keyboard shortcuts. I am using 15.10 and it uses Ctrl +Super+D for minimizing all windows and showing desktop
