A long time ago that I wanted to upload a post like this. But I always forgot. When I finally put together a more or less decent list of shortcuts available for both Unity and for Gnome-Shell. Come to see:
Alt + F2: Run an application. For this you have to use the command that would write in the terminal.
Alt + F1: Switch between the Overview and Desktop.
Alt + Tab: Switch between applications. You can change the appearance with the Gnome-Shell extensions
Alt + Shift + Tab works similar, but with applications in reverse.
Ctrl + Alt + Arrow Up / Down: Switch between desktops.
Ctrl + Shift + Alt + R: can record your desktop. It ends with the same combination.
Ctrl + Alt + Shift + Arrow Up / Down: Move the current window to a different desktop.
Windows key: Switch between applications or desktops. I must say that is what I like, it works very fast.
Alt + [Key + Tab Down]: When you run this combination shows the same but we can see that each application has open windows.
Ctrl + Alt + Tab: Switch Opens accessibility.
