Switch devices at once for both MX Keys and MX Master 3
Make it so that when the switch device key on either MX Keys or MX Master 3 is pressed, both Keys and Master 3 will switch devices together. If not it's very troublesome to have to switch by clicking two buttons (especially the Master 3 - have to click twice if just switching between 2 devices).

Totally agree. I've just received my combo pack and it is huge dissapointment because of that ! :(

I agree as well, it sounds like such a simple, powerfull and streamlined feature ; I can't understand why Logitech is not implementinfg it ? It is a very low hanging fruit to develop and a must-have for such a high-end product.
I know the software "Flow" is supposed to enable that, but it is not possible to install it on every computer (espacially professionnal IT-restricted corporate computers - which is probably the primary base of customer targets).
Please, at least explain why you don't do any effort to answer this client request going all the way back to 2020 ? It feels like Logitech is deliberately spitting on its fanbase of customers.

I agree - this would really help workflow when working on multiple machines.

MX Keys and MX Master 3. Please make the option of switching both keyboard and mouse at the same time or at least allow the mouse to use a button on top. Turning the mouse upside down is a real pain!

Do you have any news about this Logitech team? So many people are using logitech combo for work - make it 1 button finally please!
This has already been done by some individuals on github
https://github.com/Logitech/logi_craft_sdk/issues/28#issuecomment-613815171I can't do that with my work laptop! If some individual made it with ease, it seems that brand like logitech should not have any issues with it.
Please fix it

I would love this too - but not only for the MX Keys, but for any Logi keyboard that has Easy-Switch buttons - such as the Ergo K860 - and any mouse that also has Easy-Switch buttons.
It should be possible to bind the keyboard Easy-Switch buttons with the mouse Easy-Switch buttons, so that both work in sync with each other.

I would really appreciate this feature, as I use the same mouse and keyboard for both work computer and personal computer and, at the start and end of each day, I have to do the same task of raising my MX Master 3, clicking the button two times, put it back, and switch the MX Keys, too.
