Trying this one. It worked with a simple script mapping CAPSLOCK to the default Push-to-talk (OPTION + Space);

   ```
   {
    "description": "Caps Lock to Option+Space (Handy push-to-talk)",
    "manipulators": [
        {
            "from": { "key_code": "caps_lock" },
            "to": [
                {
                    "key_code": "spacebar",
                    "modifiers": ["left_option"]
                }
            ],
            "type": "basic"
        }
    ]
   }
   ```
