Tricky problem. For a given key combination, you cannot just define a new QShortcut for that because it just doesn't work (nothing happens). And every user defined key combination has a QShortcut set up on startup (even if there is no corresponding operation), which means as it stands none of them can be changed after startup. So unless you can change the operation that is called for an existing QShortcut, this seems like an intractable problem.
