This is what it's like to bring your car to the mechanic, isn't it?

The good news: I've been stuffing my brain by memorizing more Jaws keyboard commands and updating my skills using other apps.

The bad news: at some point I accidentally turned on a Jaws sound effect that makes a slight buzzing sound to signify SOMETHING IMPORTANT, but I'm not sure what. It happens when I'm down arrowing through a document.

Now I'm really hoping I can manage to persuade MCB to give me a Jaws upgrade, because I don't think I am ever going to figure out what is making that weird noise.
