title: When would you use the UITestControl.Find method?
body: <p>When checking whether a page/screen has loaded, I often use the UITestControl.WaitForControlExist() method, but I am finding example code that follows the ctl.WaitForControlExist() with otherCtl.Find() calls on the parent controls. Like this:</p>
  
  <pre><code>var tab = UIMainMenuExtWindow.UIItemWindow.UIRibbonClient.UISolutionsTabPage;
  tab.WaitForControlExist(3000);
  UIMainMenuExtWindow.Find();
  UIMainMenuExtWindow.UIItemWindow.Find();
  UIMainMenuExtWindow.UIItemWindow.UIRibbonClient.Find();
  UIMainMenuExtWindow.UIItemWindow.UIRibbonClient.UISolutionsTabPage.Find();
  tab.Find();
  Mouse.Click(tab);
  </code></pre>
  
  <p>Does this code make sense? What is the purpose of the 'Find()' calls?</p>
