The f-keys—f1, f2, f3, f4, f5, f6, f7, f8, f9, f10, f11 and f12, are also known as the function keys and can be used to perform some special functions. They can be used alone on their own and also can be combined with other keys like Shift, alt, the windows key and ctrl to perform some other functions.

Also other than their primary functions, the f-keys also can be used to get a function or action depending on softwares, such as Word, Excel and so on.

The function of the f-keys when used alone are represented on each of the keys with some signs and demarcations, such as the f9 being used to reduce the screen brightness and f10 used to increase the brightness, both represented with something that looks like sunlight. These functions may defer depending on each laptop model and/or maker, to get other functions of the function keys, please check the signs made on your keyboard.
