Your question wording is confusing, but I will attempt to guess what you mean and answer it.
Some (but not all) keyboards have a backlight to help you identify the keys in low lighting conditions. On such keyboards a pair of keys (usually multifunction "f keys") are used to adjust the brightness of this backlight to meet the user's needs. That is the purpose of the key on the keyboard that you are asking about.
