title: WPF How to disable NavigationWindow commands
body: <p>I use pages and NavigationWindow:</p>
  
  <pre><code>navigationWindow = new NavigationWindow();
              navigationWindow.Height = 200;
              navigationWindow.Width = 100;
              navigationWindow.WindowState = WindowState.Maximized;
              page = new IntroPage();
              navigationWindow.Navigate(page);
              navigationWindow.Show();
  </code></pre>
  
  <p>I navigate by using GoBack and GoForward methods, but I don't want to use them by shortcuts (function buttons in mouse etc.) How can I disable these shortcuts?</p>
