Review on Wireless Logitech MK240 Nano Keyboard 920-008212 with Nano Receiver by Taufik ᠌

Got pros: Pleasant to the touch keyboard. Nothing sticks and hangs. Most of all I liked the fact that there is only one adapter for the mouse and keyboard, that is, it won’t take up many slots, which is good if you have a laptop. Also included are 4 batteries, you can immediately safely test. Some cons: I can't use the top buttons to control music, for some reason they only perform the functions of the F keys. Tell me, is this a keyboard malfunction or do I need to install some kind of driver or hold down a key combination?
