## 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.

if (nearestSuspenseElement === null) {
      modalDialogDispatch({
        type: 'SHOW',
        content: <CannotSuspendWarningMessage />,
      });
    } else {
      const nearestSuspenseElementID = nearestSuspenseElement.id;
      
      
      if (nearestSuspenseElement !== element) {
        dispatch({
          type: 'SELECT_ELEMENT_BY_ID',
          payload: nearestSuspenseElementID,
        });
      }
      const rendererID = store.getRendererIDForElement(
        nearestSuspenseElementID,
      );
      
      if (rendererID !== null) {
        bridge.send('overrideSuspense', {
          id: nearestSuspenseElementID,
          rendererID,
          forceFallback: !isSuspended,
        });
      }
    }
  }, [bridge, dispatch, element, isSuspended, modalDialogDispatch, store]);
