Review on Keyboard + mouse set Logitech MK850 Performance, black, English/Russian by Jnis Zeile ᠌

If you are not familiar with the Logitech keyboard guru, then you will not be able to make a print screen with it. I often use this. I'd love to meet the gurus. But at the moment I want to break the head of the creators of this keyboard with their own device. Its pros: Keyboard. The buttons are easy to press. The feet under the keyboard provide two levels of elevation for the back of the keyboard. The wrist support is soft. Important: switching between 3 devices is conveniently performed on both the keyboard and the mouse. Mouse buttons can be customized to your commands. There is a gesture button. I counted 9 buttons in total. This kit is connected to both PC and Samsung smart TV Has some cons: Most importantly: where is the instruction with the meaning of the buttons / keys on the keyboard and mouse ? If the mouse still somehow manages to be configured in the software, then the keyboard layouts are complete trash! Search engines don't return results. WHO KNOWS? Give plz a file with the meaning of the keys? or a link? Or just tell me what all these buttons mean? and with and without fn, F1-F12. And this is a LACK of the KEYBOARD and the whole set - NO INSTRUCTIONS! It's like buying a cool car, but you know how to use 3 pedals, and the whole dashboard is just an illumination without meaning for you! For some reason, it strongly attracts dust, although I hide it in a box at night.
