@zudn@Aslanmane Yeah, Fn is usually part of the #keyboard itself — most keyboards (Mac computers are an exception) can't even tell the computer when Fn is pressed. Fn is just for having more "keys" than physical buttons on the keyboard. Note that many full-size keyboards do not need an Fn key.
#Linux#Ubuntu appears to have changed my keyboard shortcut for turning off/on sound, from F1 to Fn+F1. Why cause me grief? Where do I return it to previous setting? Don't see anywhere to do that. 😪
