Logitech Flow
You can work on multiple computers with your MX Keys keyboard. With a Flow-enabled
Logitech mouse, such as MX Master 3, you can work and type on multiple computers with the
same mouse and keyboard using Logitech Flow technology.
You can use the mouse cursor to move from one computer to the next. The MX Keys keyboard
will follow the mouse and switch computers at the same time. You can even copy and paste
between computers. You will need to install Logi Options+ software on both computers and
follow these instructions.
You can check which other mice are Flow enabled here.
