CapsLock to send Shift+Enter for chat tools

gistfile1.txt

Here's how to set up Karabiner-Elements to map Caps Lock to Shift+Enter:
Step 1: Install Karabiner-Elements

Download from https://karabiner-elements.pqrs.org/
Install and grant the necessary permissions when prompted

Step 2: Create a Custom Rule

Open Karabiner-Elements
Go to the Complex Modifications tab
Click Add rule button at the bottom
Click Import more rules from the Internet (this opens a browser)
Or, better yet, manually add a custom rule:

Step 3: Add Custom JSON Rule

In Karabiner-Elements, go to Misc tab
Click Open config folder
Navigate to karabiner.json or create a custom rule file in the assets/complex_modifications/ folder
Create a new JSON file (e.g., caps_to_shift_enter.json) with this content:
```json
{
    "description": "New Rule (change left_shift+caps_lock to page_down, right_shift+caps_lock to left_command+mission_control)",
    "manipulators": [
        {
            "from": {
                "key_code": "caps_lock",
                "modifiers": {
                    "mandatory": ["left_shift"],
                    "optional": ["any"]
                }
            },
            "to": [
                {
                    "key_code": "page_down",
                    "modifiers": []
                }
            ],
            "type": "basic"
        },
        {
            "from": {
                "key_code": "caps_lock",
                "modifiers": {
                    "mandatory": ["right_shift"],
                    "optional": ["any"]
                }
            },
            "to": [
                {
                    "apple_vendor_keyboard_key_code": "mission_control",
                    "modifiers": ["left_command"]
                }
            ],
            "type": "basic"
        },
        {
            "from": {
                "key_code": "caps_lock",
                "modifiers": {
                    "mandatory": [],
                    "optional": ["any"]
                }
            },
            "to": [
                {
                    "key_code": "return_or_enter",
                    "modifiers": ["left_shift"]
                }
            ],
            "type": "basic"
        }
    ]
}
```

Step 4: Enable the Rule

Go back to Complex Modifications tab in Karabiner-Elements
Click Add rule
You should now see "Map Caps Lock to Shift+Enter"
Click Enable
