## The current behavior

The full value of the `key` is very difficult / impossible to find and use in the interface of the React Devtools.

![Kapture 2020-04-22 at 11 47 47](https://user-images.githubusercontent.com/1935696/79997715-25222680-84ba-11ea-97ba-51f1679a8c91.gif)

Only managed to find it by accident :(

## The expected behavior

The `key` is visible in the props list to the right.

### Detailed Proposal

As mentioned below in https://github.com/facebook/react/issues/18702#issuecomment-617924196

Add a light divider and new section in the props panel to the right.

Potentially also add a question mark that shows an explanation about the fact that things in this section are not really props.

path.forEach(key => {
      if (!current[key]) {
        current[key] = {};
      }
      current = current[key];
    });
  }
  function createIsPathWhitelisted(
    key: string | null,
    secondaryCategory: 'hooks' | null,
  ) {
     T
     T
    return function isPathWhitelisted(path: Array<string | number>): boolean {
      switch (secondaryCategory) {
        case 'hooks':
          if (path.length === 1) {
             N
            return true;
          }
          if (
            path[path.length - 1] === 'subHooks' ||
            path[path.length - 2] === 'subHooks'
          ) {
             D
             s
             W
            return true;
          }
          break;
