Lion: Querying keyboard shortcuts?

In Lion, is there a way within AppleScript to query existing keyboard shortcuts?

In other words, I’d like to be able to query the set of shortcuts within System Preferences->Keyboard->Keyboard Shortcuts->[ITEM], where “[ITEM]” is one of the items in the lefthand column, such as Launchpad & Dock, Mission Control, etc.

Thanks in advance for any suggestions or pointers to docs.
