You can attach to this event:

Windows.UI.Xaml.Window.Current.CoreWindow.Dispatcher.AcceleratorKeyActivated

e.g.,

Window.Current.CoreWindow.Dispatcher.AcceleratorKeyActivated +=
    (window, e) =>
    {
        switch (e.VirtualKey)
        {
            case VirtualKey.Number1:
                // ...
                break;
            case VirtualKey.Number2:
                // ...
                break;
            // ...
        }
    };
