Remap Caps LOCK to ESC

[chbroecker]

maybe it is also possible to have both CTRL and ESC on Caps lock:

• CTRL for holding caps lock
• ESC for tapping caps lock
• definitely possible on macos (see https://github.com/jasonrudolph/keyboard)
• not sure about ubuntu (maybe see https://unix.stackexchange.com/questions/320269/change-behaviour-of-modifier-keys)

macOS

• find out how to do the remapping by script
• it is easy to do in settings but I haven't looked up how to do it in the terminal

ubuntu

• haven't tested if this works
• Remapping CAPS-LOCK to ESC
• in /etc/default/keyboard or in /etc/default/console-setup
  change XKBOPTIONS="" to XKBOPTIONS="esc:swapcaps"
• sudo dpkg-reconfigure -phigh console-setup
• reboot
