[arch-general] Cannot Find Desktop in GNOME3

After upgrading my box to GNOME 3 last week, I can't seem to find the desktop anywhere on my gnome setup. I use the keyboard exclusively for navigating around so I would normally use Ctrl+Alt+d to open the desktop for keyboard focus. Alas I cannot do that any more. Also, with prior versions of Gnome, pressing Ctrl+Alt+Tab would toggle you through the Bottom Panel, Top Panel, and the Desktop. Now it only toggles between the top and bottom panels. Has the desktop, as we know it, gone away? At the moment, I am using fallback mode because gnome-shell is completely broken as far as screen reader accessibility is concerned. Any ideas would be greatly appreciated; thanks.
