iit pleases me that PCs are finally giving us enough keys to represent them all.
The new key replaces either the right-ctl or menu key, so you're not getting any new keys. Basically, the key that was already there just sends a different keycode. Stupid.
On keyboards where they replaced the control key, I would map it back to control. There's no way I'm going to go through finger contortions to hit the control combos for keys on the left side of the keyboard.
On my current keyboard, I already have the useless menu key mapped to the (missing) right-windows key (which on Linux is in turn mapped to "super"), so I can do all the combinations with either hand. If they replace the menu key with the copilot key, I'd map it to the windows key.
