  "message": "Enable folding of chapter listing in navigation sidebar\n\nWe have many chapters and subchapters.  Listing all of the subchapters\nin the navigation sidebar by default can make it difficult to see the\nhigh level structure of the Reference and can inhibit rapid navigation\nbased on that hierarchical structure.\n\nFortunately, mdbook has an option to fold the chapter listing.  This\ncauses only the top-level chapters to be shown by default while giving\nthe user the ability to unfold individual chapters.  Let\u0027s turn on\nthat option.\n",
