Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    Set<AWTKeyStroke> set = new HashSet<AWTKeyStroke>(KeyboardFocusManager.getCurrentKeyboardFocusManager()
            .getDefaultFocusTraversalKeys(KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS));

    set.add(KeyStroke.getKeyStroke("F3"));
