====== Caps lock, control and command ======

  * System settings -> Customise modifier keys -> Map caps lock to command
  * If you need anything more complex at the system level, karabiner looks like the right tool
  * These are my mappings as of March 2023:
    * caps lock -> command (for everything)
    * leftmost key (control or function) -> caps lock (same as linux/windows)
    * second from left (function or control) -> function/"globe"
    * option (windows key location) -> control (main key for the window manager because osx ignores it, position consistent with windows)
    * command (alt key location) -> option (with iterm2 sending alt hex codes) -- on mac option+left/right/backspace/delete is almost always mapped to move/delete by one word and I haven't found a way of avoiding having to get used to this although karabiner-elements could probably do it
  * Install one of your saved keymaps for iterm2, to map most command combinations to control and some opt combinations to alt, plus to get sensible command/option+arrow key combinations working
