  public static void main(String[] args) throws Exception {
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JTextPane editorPane = new JTextPane();
    editorPane.setSelectedTextColor(Color.red);

      public void mouseReleased(MouseEvent e) {

        if (e.isPopupTrigger() || e.getButton() == MouseEvent.BUTTON1) {
