# ## Remap keys (macOS)
#
# Using karabiner I have remapped my keyboard.
#
#     p ü + ö ä # < -   (layout: de)
#     ----------------------------------
#     \ { }   [ ] |     Alt_L
#     \ { }   [ ] | ~   Cmd_R
#       [ ]             Alt_L + Shift_L
#
# Karabiner provides a command-line interface to activate
# or deactivate settings:
#
#     karabiner set karabiner set remap.optionR2forwarddelete 1
#     karabiner set karabiner set remap.optionR2forwarddelete 0
#
# Also, this script provides a short comamnd to create and apply
# new key remappings.
#
# They keycodes can be looked up here:
# https://github.com/tekezo/Karabiner/blob/master/src/bridge/generator/keycode/data/KeyCode.data
#
# But be aware, they always refer to the us keyboard layout.

# The new mapping is appended to
