title: How to edit the Style of a Scrollbar of a ScrollViewer?
body: <p>I already know how to edit the <strong>ScrollViewer</strong>'s Template by editing a copy of its template. But how do I edit the <strong>Scrollbar</strong>-that's-inside-the-ScrollViewer's Style?</p>
  
  <p><sub>(What I want is to change the <code>BeginTime</code> of its <code>FadeOut</code> animation as suggested in <a href="https://stackoverflow.com/a/37439430/939213">this</a> answer. I don't want to change all Scrollbars' behavior in the app.)</sub></p>
  
  <p>If there's some way to do this in code instead of XAML that would be great.</p>
