Reusing Copilot Key (on HP Zbook Ultra G1a)

The Copilot key does nothing in linux and takes up a lot of space on the keyboard. I remapped mine using keyd to window overview (win+w)

  1. Add repo:sudo dnf copr enable alternateved/key
  2. Install keyd: sudo dnf install keyd
  3. Edit configuration: sudo nano /etc/keyd/default.conf
