title: MS Word's Add-in TextChange Event in C#
body: <p>I have a Microsoft Word Add-in that find the similar words in a text (But When I click a button !)</p>
  
  <p>My question is : how to call a function when user typed words ?  </p>
  
  <p>In other word , i want an event like "TextChange" or "Keypress" when user typing to get the current word and process it and get it's similar words.</p>
  
  <p>Somethings Like this :</p>
  
  <pre><code>private void TextChangeEventOfCurrentActiveDocument(object sender, System.EventArgs e)
  {
      ...
  }
  </code></pre>
  
  <p>Any Other idea that i can get new words that user typed ?  </p>
  
  <p>Thanks.</p>
