## 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.

const {inspectedElementID} = useContext(TreeStateContext);
  const dispatch = useContext(TreeDispatcherContext);
  const {canViewElementSourceFunction, viewElementSourceFunction} = useContext(
    ViewElementSourceContext,
  );
  const bridge = useContext(BridgeContext);
  const store = useContext(StoreContext);
  const {dispatch: modalDialogDispatch} = useContext(ModalDialogContext);
  const {
    copyInspectedElementPath,
    getInspectedElementPath,
    getInspectedElement,
    storeAsGlobal,
  } = useContext<InspectedElementContextType>(InspectedElementContext);
  const element =
    inspectedElementID !== null
      ? store.getElementByID(inspectedElementID)
      : null;
  const inspectedElement =
    inspectedElementID != null ? getInspectedElement(inspectedElementID) : null;
  const highlightElement = useCallback(() => {
    if (element !== null && inspectedElementID !== null) {
      const rendererID = store.getRendererIDForElement(inspectedElementID);
