📥 Installation

1. Open the Extensions view in Visual Studio Code (Cmd+Shift+X or Ctrl+Shift+X).
2. Search for Key Tracer and click Install.
3. Once installed, the extension is ready to use!

🚀 Usage

1. Open any JSON file in VS Code.
2. Hover over any JSON key to see its full path.
3. Click on the "Copy Path" link in the hover to copy the path to your clipboard.

💡 Example

For a JSON file like this:

{
  "parent": {
    "child": {
      "target": "value"
    }
  }
}

When you hover over the "target" key, you'll see:

Full Path: parent.child.target
[Copy Path]

Clicking "Copy Path" will copy parent.child.target to your clipboard.

⚙️ Configuration

You can customize the delimiter used in the path:

1. Open VS Code Settings (Cmd+, or Ctrl+,).
2. Search for "Key Tracer".
3. Modify the "Delimiter" setting to use your preferred separator (default: '.').
