In the blog's comments, Felipe Morales linked this extension : https://extensions.gnome.org/extension/10/windownavigator/, and it's quite good. You can use alt+<Number> to select a window while in 'exploded view'.
Felipe here: I would also recommend another extension that provided window search abilities to the overview, so I could type "hacker news" or "handler.py" and go to the window I needed to, but it doesn't seem to be updated to gnome 3.6. I've been looking at the code and I can't figure out what is wrong with it.

I rarely use that many windows!
The 'exploded' window view shows windows on current workspace so being able to select one from the keyboard means I can group the windows by task/project in different workspaces.
Oh, you mean perform actions on the windows without leaving the overview? That would be nice.
EDIT: I seem to be have been a bit confused before.

Very nice too, works with GS 3.6 as in Gnome Ubuntu Remix 12.10. Thanks for pointing out the link.
I think some functionality along these lines should be provided by the basic GS though.
This is actually an accessibility problem and as such it should just work by default (no extensions or anything). The difficulty is spending time to figure out the best way to do this as well as trying&developing the various solutions. I do hope it gets solved soon (GNOME 3.8 or 3.10).
Marc has nailed it here for me. On the rare occasions I use the 'exploded view' I want to be able to tab between the windows.
I mainly use Alt-Tab and Alt-backtick to move between applications and windows at present, but adding a keyboard mode for switching within the dash would help with organising workspaces by task irrespective of application...
