 /**
  * A hook that makes it easy to use the arrow keys to manage focus of items in a list
  *
  * Recommendation: To ensure stability, wrap the `onFocusedIndexChange` function with the useCallback hook before using it with this hook.
  *
- * @param {Object} config
- * @param {Number} config.maxIndex – typically the number of items in your list
- * @param {Function} [config.onFocusedIndexChange] – optional callback to execute when focusedIndex changes
- * @param {Number} [config.initialFocusedIndex] – where to start in the list
- * @param {Array} [config.disabledIndexes] – An array of indexes to disable + skip over
- * @param {Boolean} [config.shouldExcludeTextAreaNodes] – Whether arrow keys should have any effect when a TextArea node is focused
- * @param {Boolean} [config.isActive] – Whether the component is ready and should subscribe to KeyboardShortcut
- * @returns {Array}
