I hoped that in terms of use there would be an improved version of k310 - see photo, but it turned out, to put it mildly (especially if you compare prices), not very I understood what is the main incompatibility between mx master 3 and mx keys: the mouse is made for the right hand, but its dimensions do not allow it to be conveniently placed on the right, since the keyboard has a numeric keypad bought for remote work together with mx master 3, because the poppy keyboard lacks some writing buttons when working under venda and in the shell useful info (forcibly switch the layout): iOS: Fn + i macOS: Fn + o Windows: Fn+p logitech options does not override keyboard settings, but override touchpad settings - where is the logic, logitech? I got the impression that the product is not bad, but the software spoils everything wrote in support - they answered after 9 days, the answer is: You go to the product registration guide, register and request the repair of your product, and they will contact you in three days.
