We're not weighted down with people who believe the best way to explain something is to have them watch a video.* "How do I make a script to do such-and-such?" "I've got a video that explains it." So that's why I couldn't get it to work! I was holding the mouse in the wrong hand, and looking in the wrong place for the Edit menu.
Save the videos for showing me what choux pastry is supposed to look like when you stir it, or what the paint is not supposed to look like when you open the undated can.
* Or look at pictures. I've downloaded that ### google SEO pdf at least six times because I keep forgetting I've already read it.
