I've begun getting a repeating, and exceedingly annoying, message on some Websites on Safari. VoiceOver says something like, "Press alt+1 to use screen reader mode; stop this message with alt+0." But, I'm using a Mac, and of course have no "alt" key. I've tried option, command, control, various combinations, to no avail.
Anyone know how to stop this? It's making me crazy!
