title: How do ActiveSheet, ActiveWorkbook.ActiveSheet and Application.ActiveSheet behave differently?
body: <p>I am in the habit of of always using <code>ActiveSheet</code> like this: <code>ActiveWorkbook.ActiveSheet</code>.  I recently stumbled across <a href="http://Application.ActiveSheet%20Property" rel="nofollow noreferrer" title="this Microsoft Page">this Microsoft page</a> with code that includes <code>ActiveSheet</code> without <code>ActiveWorkbook</code>.  The title of that page is <code>Application.ActiveSheet</code> Property.</p>
  
  <p>Is there a difference between these three lines of code?</p>
  
  <pre><code>ActiveSheet
  ActiveWorkbook.ActiveSheet
  Application.ActiveSheet
  </code></pre>
