Is this proper way to disable shortcut keys of SfRichTextBoxAdv?

        public MainWindow()

        {

            InitializeComponent();

            var removingGestures = new List<InputBinding>();

            foreach (InputBinding inputBinding in this.documentEditor.InputBindings)

            {

                var gesture = inputBinding.Gesture as KeyGesture;

                if (gesture != null && gesture.Modifiers == ModifierKeys.Control)

                {

                    if (gesture.Key == Key.O) { removingGestures.Add(inputBinding); }

                    if (gesture.Key == Key.S) { removingGestures.Add(inputBinding); }

                    if (gesture.Key == Key.N) { removingGestures.Add(inputBinding); }

                }

            }

            foreach (var gesture in removingGestures)

            {

                this.documentEditor.InputBindings.Remove(gesture);

            }

            this.DataContext = this.Model = new MainPageViewModel();

        }
