What to do with special keys on laptops

However, these elements that are integrated, although very similar to the rest, have some characteristics that make them somewhat special. In fact, each manufacturer and many of its models have keyboards adapted to it for more effective use.

Specifically, we refer, as in the previous case, to certain special keys that they include to control various sections of the computer itself . These characteristics, for example, can be found in the function keys that we have seen before, in the function keys themselves, F.
