  8: Multiple Export Options

  9: Right-click context menu

      Copy Path As - Export path in JSONPath, JQ, JavaScript, or Python format
      Copy Key - Copy just the key name
      Copy Value - Copy the value (formatted for objects and arrays)
      Copy Complete - Copy the entire object or array at that location
  Edit Options:
