I have both Mx Keys and MX master 3S mouse that can be paired to multiple devices. I have an idea... Since I use multiple computers, I have noticed that it is very easy to switch my MX keys to my other computers but I find it kind of annoying to have to click the under button for the mouse and it's just not seamless as the MX Keys. My idea is that, since the mouse and the keys are both connected and they both have bluetooth capability, Why not just have the keyboard do the switching for both the keyboard and mouse by one Click in the keyboard. There is three buttons on the keyboard that can make everything seamless and streamline the process of having to lift the mouse, and press the button. Since both mouse and keyboard are connected why not have the keyboard send a signal to switch. So the keyboard would have the mouse connected to it or signal the mouse to switch over when the device switch button on the MX Keys is pressed.
