Since it's storing an locally defined (ddx-internal) struct, it's better not to abuse some globally defined key for this. It just happened to work before, since CursorScreenKey is only used by DDX (and there's only one DDX per executable) and they currently (!) have the same size (pointer) - but that's a fragile programming style, so clean it up.
