如何在Caliburn.Micro中绑定关键手势？

<Button x:Name="MyButton" Content="Click Me" />

public void MyButton()
{
    // 处理关键手势的逻辑代码
}

public MyViewModel(IEventAggregator eventAggregator)
{
    eventAggregator.Subscribe(this);
}

public class MyViewModel : Screen, IHandle<KeyGestureEvent>
{
    public void Handle(KeyGestureEvent message)
    {
        if (message.Gesture == KeyGesture.KeyDown && message.Key == Key.Enter)
        {
            MyButton(); // 调用处理关键手势的方法
        }
    }
}

protected override void Configure()
{
    var eventAggregator = new EventAggregator();
    container.Singleton<IEventAggregator>(eventAggregator);
    container.PerRequest<MyViewModel>();
}
