WPF menus with shortcuts and custom RoutedCommand

Im new to WPF so i might be missing something. I have a simple function in my MainWindow class called StartService. I wanted to add a menu item "Start Service" with a shortcut Ctrl+S to my application. I had to do the following:

1. In my MainWindow class i had to define:

   public static RoutedCommand StartServiceRoutedCmd = new RoutedCommand();

2. In my XAML code i added:

<MenuItem Header="_Start Service" InputGestureText="Ctrl+S" Click="OnStartService" />

<Window.CommandBindings>
    <CommandBinding Command="{x:Static loc:MainWindow.StartServiceRoutedCmd}" 
                    Executed="OnStartService" />
</Window.CommandBindings>

<Window.InputBindings>
    <开发者_如何转开发KeyBinding Command="loc:MainWindow.StartServiceRoutedCmd" Gesture="CTRL+S" />
</Window.InputBindings>

Things are working. I'm wondering if this is the correct and organized way to go? I am gonna need a shortcut for my StopService function. Does this mean i will need to define a new RoutedCommand StopServiceRoutedCmd, and so on for every shortcut i need?

<Window.CommandBindings>
       <CommandBinding Command="{x:Static loc:MainWindow.StartServiceRoutedCmd}" 
                Executed="OnStartService" />
       </Window.CommandBindings>

<Window.InputBindings>
       <KeyBinding Command="loc:MainWindow.StartServiceRoutedCmd" Gesture="CTRL+S" />
</Window.InputBindings>
