title: Get key combination code of multiple keys
body: <p>I want to ask you can I get key code combination of multiple keys. For example I can get the key code from this example:</p>
  
  <pre class="lang-java prettyprint-override"><code>public void handle(KeyEvent event) {
      if (event.getCode() == KeyCode.TAB) {
      }
  }
  </code></pre>
  
  <p>But how I can get the key code of this example:</p>
  
  <pre class="lang-java prettyprint-override"><code>textField.setText("");
  // Process only desired key types
  if (event.getCode().isLetterKey()
          || event.getCode().isDigitKey()
          || event.getCode().isFunctionKey()) {
      String shortcut = event.getCode().getName();
      if (event.isAltDown()) {
          shortcut = "Alt + " + shortcut;
      }
      if (event.isControlDown()) {
          shortcut = "Ctrl + " + shortcut;
      }
      if (event.isShiftDown()) {
          shortcut = "Shift + " + shortcut;
      }
      textField.setText(shortcut);
      shortcutKeyEvent = event;
  } else {
      shortcutKeyEvent = null;
  }
  </code></pre>
  
  <p>Is it possible to get the key code combination of these keys <code>Ctrl + Tab</code> or <code>Ctrl + A</code>?</p>
