Your ShowRegions class should look like :

using System;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
using Firefly.Box;
using ENV;
using ENV.Data;

namespace Northwind.TestExercies
{
    public class ShowRegions : UIControllerBase
    {

        public readonly Models.Region Region = new Models.Region();

        public ShowRegions()
        {
            From = Region;
            Handlers.Add(System.Windows.Forms.Keys.F9,HandlerScope.CurrentTaskOnly).Invokes += e =>
            {
                System.Windows.Forms.MessageBox.Show("I am handling the F9 keyboard event!");
            };
            Handlers.Add(System.Windows.Forms.Keys.F10).Invokes += e =>
            {
                System.Windows.Forms.MessageBox.Show("I am handling the F10 keyboard event!");
            };
            Handlers.Add(System.Windows.Forms.Keys.F5, HandlerScope.CurrentTaskOnly).Invokes += e =>
            {
                Create<Customers.Exercises.IShowCustomerPerRegion>().Run(Region.RegionID);
                e.Handled = true;
            };

            hF5.BindEnabled(() => Region.RegionID == 1);

            Handlers.Add(Command.UndoChangesInRow, HandlerScope.CurrentTaskOnly).Invokes += e =>
