How can I use my Apple bluetooth keyboard for keyboard navigation on my iPad? I'm using an Apple bluetooth keyboard with my iPad. Even in Safari, arrow keys, Cmd-arrow for forward and back, Cmd-D for bookmark, etc do not work.  The only useful keyboard navigation is Return, Tab and Shift-Tab.

Are there perhaps some jailbroken apps that provide some sort of keyboard navigation shim?  Perhaps through GUI macros?
I am sorry to say that I am unaware of any apps (jailbroken or otherwise) that add keyboard navigation to the iPad.
