Can I get Unity-style Super+[1-9] keyboard shortcuts for launching apps in Gnome Shell?
I've just installed Gnome Shell instead of Unity, and so far I like it more. However, there's something from Unity that Gnome Shell is lacking, and that's the ability to launch the shortcuts from the dash using Super + n, where n = 1,2,3...
Is there a way of configuring it so it works the same way?
