Actually, I might have found a very interesting alternative. This
thought is to use the "tab" feature of Mozilla. I can pre-load all the
"slides" into corresponding tabs. For a long talk, I can further sort
related tabs into seperate window. One problem, I don't know how to
switch (w/o using a mouse) between tabs/windows.
Preparing the HTML documents is not a problem; there are plenty of
tools. But putting them together so that they can be presented in an
orderly fashion is the problem. As George mentioned, gqview would do a
very good job, but it lacks the flexibility of switching between
non-contiguous slides.
With HTML/Mozilla, of course, you can embed animations, sound, and
hyperlinks. The last feature is important if I want to show a document
in pdf format.
