title: JavaScript for handling Tab Key press
body: <p>As we know, when we click on <kbd>TAB</kbd> key on keyboard, it allows us to navigate through all active href links present open webpage. Is it possible to read those urls by means of JavaScript?</p>
  
  <p>example:</p>
  
  <pre><code>function checkTabPress(key_val) {
      if (event.keyCode == 9) {
          // Here read the active selected link.
      }
  }
  </code></pre>
