Explanation:

In this scenario, you are instructing a user on how to properly use a new laptop. He asks about the special function keys that are used to perform tasks such as toggling the display or adjusting the display brightness.

The user should strike the "Fn" key in combination with the special function keys.

In Computer science, the special function keys found on the top row of a keyboard are the F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, and F12 keys. Each of the special function keys just like their name suggests are used to perform different tasks respectively as defined by the operating system of a computer.

Fn is an acronym for function. In order to use the special function keys, a user must first hold down the Fn key before pressing the specific special function key which then triggers functions configured to use this key.

For instance, "Fn+F2" is to reduce brightness on the Windows operating system. Also, "Fn+F12" is to increase audio volume on the Mac operating system.
