title: MS Word change currently selected ribbon item using COM interface
body: <pre><code>import comtypes.client as com
  
  app=com.GetActiveObject('Word.Application')
  
  app.Visible = True
  app.Resize(400, 400)
  </code></pre>
  
  <p>Using this python script one can connect to opened MS Word document and resize it.</p>
  
  <p>I need to programmatically change currently selected ribbon item. I need to emulate click on "File", "Home", "Insert", "Design" and so on. I am especially
   interested to open backstage view programmatically. Do you if there are such COM interfaces?</p>
