The keyboard is very quiet, which is nice. But what about having to press the "FN" key to use the F1 ... F12 functions. This means that if you type "F2", you will need to type FN + F2! To remedy this, install software, still, who will take up memory. It is a pity and rather incomprehensible that one can not switch this function directly on the keyboard without having to install an nth software.
