title: Create dataLayer custom event for external clicks
body: <p>I am looking to create a dataLayer push event for any time a click is made on any external link - I plan to use it as a trigger to fire a GTM tag for external link tracking. I envision it will be something like this :</p>
  
  <pre><code>&lt;script&gt;
  Some code to detect clicks on any external links
  dataLayer.push({'event': 'eventNameXYZ'});
  &lt;/script
  </code></pre>
