InputGesture modifier for "Windows" key

This is a simple question.

If I want to set the shortcut for one of my commands to Windows V, what string do I use for the "Windows" key modifier?

<Window.InputBindings>
    <KeyBinding Command="vm:MainVM.OpenDialogCommand" Key="V" Modifi开发者_如何学Cers="**WHAT DO I PUT HERE**"/>
</Window.InputBindings>

See here. Just use Modifiers="Windows".

According to this, Modifiers="Windows".
