On install, the screen cycles through logi devices that aren't mine and the MX Keys was the last one. I'm then left on a screen with the MX Keys in the center and no obvious buttons other than settings and feedback. I went into setting which was an obvious button and didn't find a way to navigate to the MX Keys settings so went back out and moved the mouse around until the MX Keys moved up and down indicating that i might be able to click on it.

I can see how this would work better with multiple devices displayed indicating that clicking one or the other would be a navigation option. With only one, I felt a bit lost at first.
