title: WPF ComboBox using letter keys for selecting items
body: <p>I have a combo box in my application and when the drop down is open I would like the user to be able to type a letter and have the drop down skip to that selection. Currently it doesn't skip to the selection. I looked up couple of stackoverflow questions and applied the changes mentioned by them </p>
  
  <pre><code>IsTextSearchEnabled="True" TextSearch.TextPath="{Binding Name}"
  </code></pre>
