No, the Logitech K120 keyboard will not change the volume of the audio from your computer. There are no media control keys on this keyboard.

You can find the details on the K120 keyboard here: https://www.logitech.com/en-us/product/k120?crid=27 . Scroll down and click on the Get Support link to find the FAQs and Quick Start Guide.

I hope this helps.

There is no manual specifically for this keyboard: The following is a keyboard diagram which may answer most of your questions: The small mode button above and between the F4 and F5 keys switches between Function and F-Key modes for the traditional Function keys. Experiment a bit when you are not working on something important.

As there is no software for this keyboard, how could there be separate functions for the Fn keys?

The operating system controls what language comes up on the screen, not the keyboard. A keyboard is just a bunch of switches with letters printed on them. The computer only sees a switch closing that is supposed to represent a letter that it is programmed for.
Your operating system may be able to operate with more than one language or you may have to buy an operating system designed for spanish.

Entering the following keystroke combination will result in the Pound Sterling sign being displayed:
While holding down the ALT key, enter 0163 (ALT+0163).

This is known ASCII Code. (Pronounced Ask-key.)
A complete list of all 256 character codes is available at http://www.ascii-code.com/ .
All manner of Latin-based characters are available. Check it out.
To use any ASCII Code, choose the "HTML Number" and substitute "ALT+0" for "&#".
In this case, the HTML Number is &#163, therefore when entering text, type ALT+0163 (NOTE: "ALT+" means "While holding down the ALT key, press and release each of the four digits in sequence, then release the ALT key.)

Hope this helps.
