Q

In which scenario would you use the Fn key and the F10 key shown here?

A. To turn the screen brightness down

B. To turn the screen brightness up

C. To turn the speaker volume down

D. To turn the speaker volume up

A

B. To turn the screen brightness up

Because of the much smaller space available for keys, some laptop keys are consolidated into special multifunction keys. These keys are accessed through the standard keys by using a special function (Fn) key. Video adjustments come in two varieties: changing the video output and dimming or brightening the screen. In this case, there is a large sun icon for brightening the screen. Some laptops will use a smaller sun to signify dimmer and a larger sun to signify brighter or plus and minus signs next to the suns or up and down arrows next to the suns. You may also see special function keys to turn network connections on or off or play, fast forward, or rewind media.
