I recently replaced my keyboard and mouse for the first time in several years.
As the number of devices I use has increased, I have purchased a keyboard and mouse that allows me to switch between three devices simultaneously, mainly Mac, Windows, and a tablet.
It supports both Bluetooth and USB receiver, so you can register them in a mixed way, for example, using Bluetooth on your tablet and Mac, and the USB receiver on Windows.
Switching between devices is also instantaneous with the press of a button, so I was able to use it without any stress. Although the keyboard and mouse themselves are old input devices, I was impressed that they are still evolving in this direction.
So far, this is just my impression of a newer device, but when I launched the setting software called Logitech Options for the first time in a while, I noticed that a new item called "Flow" had been added. I wondered what it was, selected it, and found that it was a much better function than I had imagined, so I decided to write about it on my blog.
What is Logitech Flow?
Simply put, it means that you can operate multiple devices with one mouse without having to be aware of the differences.

On the official website,
- Control between computers
- Seamless File Sharing
It is written:
Once you set up Logitech Flow, you can move your mouse back and forth between Windows and Mac, even if you're using different operating systems, without being aware that the devices are different, as if they were dual displays placed next to each other.
Furthermore, by linking the keyboard, you can switch input to the device where the mouse cursor is located, making it a very convenient feature.
As shown in the eye-catching image, I use a single mouse to switch between my Macbook and my Windows 10 desktop.
Actual behavior
This is similar to setting up a dual display, where you position the devices up, down, left and right, and when the mouse reaches the edge of the screen, the pairing is transferred to another device.
Since we can see that the 1, 2, and 3 lights are switching, we can see that the devices are not connected simultaneously, but are switched one by one. Normally, switching is done by pressing a button, but this function allows you to switch by moving the device to the edge of the screen.
There is software with similar functions, but it says it works via LAN, so I think the principle of operation is different from Logitech Flow, which switches the pairing physically. (I'm sorry if I'm wrong.)
The time lag is at a subjective level, like waiting 0.5 seconds, but it is still satisfactory.
There are still few compatible models (as of June 2016)
The mouse is the above five models
There are only three keyboards.
summary
Logitech Flow is an amazing feature.
I was impressed to see that the latest mice and keyboards with switching functions offer such benefits.
