I wanted to leave myself the option of reacting to partial lines,
or only to certain characters, and also to learn about kbd events,
to implement an imitation vi etc.

Agreed.  I'd hoped to be able to handle paste events, but no.
(I also want the previous search results to remain on the
screen as they do, but that's not hard to arrange.)
The command-line version can handle cut and paste and accents,
  http://www.pjb.com.au/esperanto/index.html
and it actually gets more downloads than the html version gets hits.

Indeed, and it's a big issue with cut and paste where you
don't have the freedom to type.  Of course if the page handled
diacriticals I'd still want to respect the x notation;
it's very ergonomic on non-esperanto keyboards.
