Catch Key Event in a Window

Question

Hello

I have a window with Web view Which uses full available space on screen I need to catch users key down event how can I achieve it?

Note my webview is navigated to some webpage (already loaded on screen).

I tried this but not firing

 private void webview_KeyDown(object sender, KeyRoutedEventArgs e)
        {
          // can't catch anything here.
        }

    

        private void webview_Loaded(object sender, RoutedEventArgs e)
        {
            webview.KeyDown += webview_KeyDown;
        }

        private void webview_Unloaded(object sender, RoutedEventArgs e)
        {
            webview.KeyDown -= webview_KeyDown;
        }
