Point at the reader element you want changed
Turn on Design mode with l or Annotations in the leaf's menu, then press the heading or code reader below. For a keyboard choice, press s, browse targets with Tab, and choose with Enter. Your comment stays beside that element as its treatment changes. Describe a shared change in the comment when both readers should inherit it.
Reader sample
export const summarize = checks =>
`${checks.passed} passed · ${checks.pending} pending · ${checks.failed} failed`;
