title: Get key combinations
body: <p>How can I get key combination of keys on keyboard E.G. (<kbd>Ctrl</kbd>+<kbd>somekey</kbd>, <kbd>Alt</kbd>+<kbd>somekey</kbd>) with Java?</p>
  
  <p>I use <code>KeyEvent</code> listener, <code>MouseEvent</code> listener for all keys on keyboard. I can catch all key event on keyboard by using that listener. But, I cannot catch key combination such as (<kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>Del</kbd>)....etc. </p>
