Gala: Windows overview mode should be keyboard navigable like Unity

[uncertainquark]

Unity can navigate between windows in the overview mode using keyboard arrow keys which is great.

It also aids when you search and filter windows, as suggested in #218.

I agree.

There is a similar function on the workspace overview, but is unpredictable.

I think the window overview should be the one where you can select the desired window using the keys and the workspace overview window selector (arrow keys) should be disabled.

The window overview and workspace overview are pretty redundant, and honestly I think we want to merge them.

Then we should report and fix issues against keyboard navigation in the workspace overview. :stuck_out_tongue:

That would be great, but the Super+A function would be lost.

Since #287 is the way we want to move forward, I'm closing this as superseded.
