This has very little utility, but might demonstrate a general
approach for using Lynx as a viewer for HTML files generated from some
other source and editing them from there.  You hit `e` in Lynx and it
calls whatever editor is defined.

Hit `o` to set options and change the
editor in there to lynx-wrapper-edit, making sure to hit the "write
changes to disk" or whatever it says checkmark before applying changes.

This works by taking the path that Lynx passes off for the filename to
edit, changing part of that path with sed to reflect where the source
file is, and then handing that to vim to edit.  After vim finishes, it
re-renders the static HTML files that Lynx is viewing.
