Keyboard focus & navigation

[franziskuskiefer]

It would be nice to navigate between workspaces when the dock is shown. At the moment the focus stays on the open application. The dock also stays open as long as the focus does not change. I think the dock should at least grab keyboard focus, allow to exit on escape and exit on clicking some place outside the dock. Navigation using arrow keys then would be a plus :)

(this is all when opening the dock using the keyboard shortcut)
