        return nil;
    }
    void (^monitorHandler)(NSEvent *);
    monitorHandler = ^(NSEvent *theEvent){
        switch ([theEvent keyCode]) {
            case 123:    // Left arrow
                NSLog(@"Left behind.");
                break;
            case 124:    // Right arrow
                NSLog(@"Right as always!");
                break;
            case 125:    // Down arrow
                NSLog(@"Downward is Heavenward");
                break;
            case 126:    // Up arrow
                NSLog(@"Up, up, and away!");
                break;
            default:
                break;
        }
    };
    // Creates an object we do not own, but must keep track
    // of so that it can be "removed" when we're done 
    [NSEvent addGlobalMonitorForEventsMatchingMask:(NSKeyDownMask) handler:monitorHandler];
    return self;
