title: How to add a listener to a JTextField for up, down left, right arrow?
body: <p>I need to write an arrow listener for my JTextField. if a try with:</p>
  
  <pre><code>public void keyTyped(KeyEvent e) {
              if (e.getKeyCode() == KeyEvent.VK_DOWN) {
                  ......
              }
  }
  ...
  </code></pre>
  
  <p>This is not good.( I think that JTextField is not responding to a special key listener.)</p>
