tty keyboard layout.md

1. Add keyboard layout to /usr/share/kbd/keymaps (e.g. /usr/share/kbd/keymaps/name-of-keymap.map.gz)
2. Unicode keys are entred like so: U+27e8
3. Do loadkeys w/ absolute path (loadkeys /usr/share/kbd/keymaps/name-of-keymap.map.gz) to test it
4. Do localectl set-keymap --no-convert name-of-keymap to enable it permanently (do pacman -Suy systemd (!) first)
