Sorry, should have been clearer in the commit message. I'm doing this just on the Microsoft spec. The co-pilot key is left-shift, Windows/Meta key, F23. Weird combo I know.... Somewhere I had a MS page...but this Tom's HW page mentions it: https://www.tomshardware.com/software/windows/windows-copilot-key-is-secretly-from-the-ibm-era-but-you-can-remap-it-with-the-right-tools I'll see if I can find something more formal. > > Peter, I thought I read somewhere that you were looking > into mapping the copilot key to a new KEY_COPILOT evdev > key for some other keyboards? > Wouldn't this require the kernel catching all three key events and doing the interpretation?
