c# - メニュー項目のショートカット

Question

以下は、メニュー項目にショートカットを割り当てようとしたものです。メニュー項目をクリックするとうまくいきますが、ショートカットが機能しません。何か案が？

<Window.CommandBindings>
    <CommandBinding Command="ApplicationCommands.Save" Executed="MyCommand" />
</Window.CommandBindings>

<Window.InputBindings>
    <KeyBinding Key="S" Modifiers="Control" Command="ApplicationCommands.Save"/>
</Window.InputBindings>

<MenuItem Header="Save" Name="MainMenu_File_Save" Command="ApplicationCommands.Save">
    <MenuItem.Icon>
        <Image Height="16" Width="16" Source="/NewGUI_WPF;component/Images/saveHS.png" />
    </MenuItem.Icon>
</MenuItem>

private void MyCommand(object sender, ExecutedRoutedEventArgs e) {...}

        {
            MessageBox.Show("Test");
        }
    }
}

<Window x:Class="test.MainWindow"

  </Window.CommandBindings>

  <Window.InputBindings>
    <KeyBinding Key="S" Modifiers="Control" Command="ApplicationCommands.Save"/>

      <MenuItem Header="Save" Name="MainMenu_File_Save" Command="ApplicationCommands.Save" />
     </MenuItem>
   </Menu>
  </Grid>
</Window>

それは私にとってはうまくいきます。それはあなたのために働きますか？
