Custom modification for Karabiner to disable the cmd-m minimise shortcut

nominimise.json

{
  "title": "Prevent unintended command-m minimising",
  "rules": [
    {
      "description": "Disable Cmd+m minimise",
      "manipulators": [
        {
          "type": "basic",
          "description": "",
          "from": {
            "key_code": "m",
            "modifiers": {
              "mandatory": [
                "command"
              ]
            }
          }
        }
      ]
    }
  ]
}

Here is new format of Karabiner shorcut:

{
    "description": "Prevent command-m minimize window",
    "manipulators": [
        {
            "from": {
                "key_code": "m",
                "modifiers": {
                    "mandatory": [
                        "command"
                    ]
                } 
            },
            "type": "basic"
        }
    ]
}

BIG THANKS!
