hello,
well done on the MX keys and MX anywhere 3 mouse. they work beautifully. one thing that is fiddly is if you want the keyboard to follow the mouse. it works but only within certain parameters. for instance, it seems like you can't have a text field which is active (awaiting input) in one computer, and then switch the mouse to the other computer and try to begin typing into a new text field (such as a web address field in a browser window). the text still shows up in the active text window on the first computer. i suppose this is a difficult problem to solve, but i had hoped it would work seamlessly. but anyway, i have turned that functionality off for now and use the buttons on the keyboard to switch between computers, while the mouse moves automatically from computer to computer.
well done, overall!
best regards,
David
