Keychron: how to remap and swap "§±" and "`~" keys on UK layout

keychron_remap.md

As the Keychron K3 keyboard with UK layout has the great L-shaped ENTER key but the uncomfortable placed "§±" and "`~" keys, here is a solution to swap both keys without any third party software on OSX.

hidutil property --set '{
  "UserKeyMapping":[
    {
      "HIDKeyboardModifierMappingSrc":0x700000035,
      "HIDKeyboardModifierMappingDst":0x700000064
    },
    {
      "HIDKeyboardModifierMappingSrc":0x700000064,
      "HIDKeyboardModifierMappingDst":0x700000035
    }]
}'

REVERSE

hidutil property --set '{
  "UserKeyMapping":[
    {
      "HIDKeyboardModifierMappingSrc":0x700000064,
      "HIDKeyboardModifierMappingDst":0x700000035
    },
    {
      "HIDKeyboardModifierMappingSrc":0x700000035,
      "HIDKeyboardModifierMappingDst":0x700000064

    }]
}'
