body: <p>I need to know if the user is clicking or CONTROL CLICKING a div element.. 
  i have seen examples on how to do it using event listeners.. but my codes are already set in place, and is using an on-element <strong>onclick</strong> method.. </p>
  
  <p>HTML</p>
  
  <pre><code> &lt;div id='1' onclick='selectMe()'&gt;blah&lt;/div&gt;
  </code></pre>
  
  <p>JS</p>
  
  <pre><code> function selectMe(){
           //determine if this is a single click, or a cntrol click 
      }
  </code></pre>
