 Sebastian Rose has written a JavaScript program especially designed to
-enhance the web viewing experience of HTML files created with Org.
-This program enhances large files in two different ways of viewing.
-One is an /Info/-like mode where each section is displayed separately
-and navigation can be done with the {{{kbd(n)}}} and {{{kbd(p)}}}
-keys, and some other keys as well, press {{{kbd(?)}}} for an overview
-of the available keys.  The second one has a /folding/ view, much like
-Org provides inside Emacs.  The script is available at
-https://orgmode.org/org-info.js and the documentation at
-https://orgmode.org/worg/code/org-info-js/.  The script is hosted on
-https://orgmode.org, but for reliability, prefer installing it on your
-own web server.
