 public MainWindow()
        {
            InitializeComponent();

            // Create the CommandBinding.
            CommandBinding cmd = new CommandBinding();
            cmd.Command = ApplicationCommands.New;

            cmd.Executed += new ExecutedRoutedEventHandler(CommandBinding_CmdKey_Executed);
            cmd.CanExecute += new CanExecuteRoutedEventHandler(CommandBinding_CmdKey_CanExecute);
            this.CommandBindings.Add(cmd);
            // Creating a KeyBinding between the Open command and Ctrl-R
            KeyBinding CmdKey = new KeyBinding();
            CmdKey.Key = Key.F;
            CmdKey.Modifiers = ModifierKeys.Control;
            CmdKey.Command = cmd.Command;
            this.InputBindings.Add(CmdKey);
        }
        private void CommandBinding_CmdKey_CanExecute(object sender, CanExecuteRoutedEventArgs e)
        {
            e.CanExecute = true;
        }

        private void CommandBinding_CmdKey_Executed(object sender, ExecutedRoutedEventArgs e)
        {
            MessageBox.Show("OK");
        }
