When the focus is on a component, any focus traversal keys set for that component override the default focus traversal keys. For an example of how to change the focus traversal keys for the entire application, see e611 Setting Focus Traversal Keys for the Entire Application.

    // Change the forward focus traversal keys for a component
    Set set = new HashSet(component.getFocusTraversalKeys(
        KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS));
    set.clear();   // Call clear() if you want to eliminate the current key set
    set.add(KeyStroke.getKeyStroke("F2"));
    component.setFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, set);
