Apparently the "Show Me How" feature just decided to function correctly on its own. It still wasn't any help, though. It said to move a section of video to an upper track and do the fading there. I simply dragged the end of the the video right where it was. The last time I tried this it didn't work. But, for some reason, it now works.

I guess all I have to do is ask for help and miraculously I'm able to do what I asked for. Strange.
