No way, I’ll have to try that. Guess I shouldn’t have thrown out the manual 13 years ago!

It’s Windows 10 where I’ve seen that actually. Also can cause weirdness on Linux because it is emulating key presses to make the shortcut happen. Maybe it’s because mine is actually a K400r.

I’ve got a K400 too which I bought like 13 years ago and have gotten a ton of use out of. It’s still going strong, even after my wife spilled tomato soup on it, but my real issue with it is that damn hard-coded Cortana shortcut that launches when you swipe the trackpad from the edge. Sure wish I could disable that.
