This is a somewhat technical post about how to remap keys in OSX using Karabiner Elements.
Get karabiner elements (https://karabiner-elements.pqrs.org/)
Give it the permissions it needs via System Preferences
Use the built in options, or of you need a more complex modification…
Go to your user folder and find the directory: ~/.config/karabiner/assets/complex_modifications
Create a file there called ‘mapXtoY.json’ and in that file paste this:
{ "title": "Remap x to y", "rules": [ { "description": "Remap x to y", "manipulators": [ { "from": { "key_code": "x" }, "to": [ { "key_code": "y" } ], "type": "basic" } ] } ] }Use Karibiner – Event Viewer to find the keycodes you need to substitute for x and y
(This is from here: https://www.youtube.com/watch?v=iiSIaMD4vqY)
Here’s an example to map F13 to Shift-Control-Option + 4
{ "title": "Remap x to y", "rules": [{
"description": "F14 to s-c-o + 4",
"manipulators": [
{
"from": {
"key_code": "f14"
},
"to": [
{
"key_code": "4",
"modifiers": [
"left_shift",
"left_control",
"left_option"
]
}
],
"type": "basic"
}
]
}] }
