Karabiner-Elements map a key to a combination keys

I'm new to Karabiner. As I understand it this program can change the keyboard mapping. I understand and able to use the "Simple modification" "From key" "To key".

But If I want to remap my Home button to CTRL+LEFT_ARROW how do I do that?

Currently on MacOs Mojave

Solution

  • Open ~/.config/karabiner/karabiner.json Edit that file, from the root level > "profiles" > "complex_modifications" > under parameters:{ ... }, add:

    "rules": [
                    {
                        "description": "Home to Control Left",
                        "manipulators": [
                            {
                                "from": {
                                    "key_code": "home"
                                },
                                "to": [
                                    {
                                        "key_code": "left_arrow",
                                        "modifiers": "control"
                                    }
                                ],
                                "type": "basic"
                            }
                        ]
                    },
                    {
                        "description": "End to Control Right",
                        "manipulators": [
                            {
                                "from": {
                                    "key_code": "end"
                                },
                                "to": [
                                    {
                                        "key_code": "right_arrow",
                                        "modifiers": "control"
                                    }
                                ],
                                "type": "basic"
                            }
                        ]
                    }
                ]

    Please note that, this will map:
