This example changes the focus traversal keys for the entire application. For an example of how to change the focus traversal keys for a particular component, see e610 Setting Focus Traversal Keys in a Component.

    // Change the forward focus traversal keys for the application
    Set set = new HashSet(
        KeyboardFocusManager.getCurrentKeyboardFocusManager().getDefaultFocusTraversalKeys(
            KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS));
    set.clear();   // Call clear() if you want to eliminate the current key set
    set.add(KeyStroke.getKeyStroke("F2"));
    KeyboardFocusManager.getCurrentKeyboardFocusManager().setDefaultFocusTraversalKeys(
        KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, set);
    
    // Change the backward focus traversal keys for the application
    set = new HashSet(
        KeyboardFocusManager.getCurrentKeyboardFocusManager().getDefaultFocusTraversalKeys(
            KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS));
    set.clear();   // Call clear() if you want to eliminate the current key set
    set.add(KeyStroke.getKeyStroke("F3"));
    KeyboardFocusManager.getCurrentKeyboardFocusManager().setDefaultFocusTraversalKeys(
        KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS, set);
    
    // Remove all forward and backward focus traversal keys for the application
    set.clear();
    KeyboardFocusManager.getCurrentKeyboardFocusManager().setDefaultFocusTraversalKeys(
        KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, set);
    KeyboardFocusManager.getCurrentKeyboardFocusManager().setDefaultFocusTraversalKeys(
        KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS, set);
