I have two macs and two PCs on a 4-port KVM. They all go to a CODE keyboard. My brain needs to remember Ctrl-C in Windows, Apple-C in Mac. You can bring up the Windows version of Spotlight by hitting the apple key in Windows; you can bring up the Mac version of Spotlight by hitting the Apple key and the space bar in Mac.
And somewhere in there, if I fat-finger a Mac command in Windows, Windows brings up a dialog that says "we got rid of Cortana" rather than not letting me accidentally trigger Cortana.
Fuckin' Clippy, man.
