Agree. I did never ever see the teacher explaining few lines of code during 20 minutes without saying anything else, than is displayed on the screen.


During this 20 minutes I learn from the teacher, that _ means "wildcard". Everything else is on the VS screen



With my regards, Kathy: much appreciate your videos, but in this case one JPG wilth codeshot will say exactly the same, what this 20 minutes movie.
