Thanks for all of your responses and for taking the time to help me. I'll try to
answer your questions. As far as possible I  use the "stock" ubuntu (maverick -
10.10) repositories for emacs and its associated software. So I'm using emacs
23.1.1 and org-mode 6.36c. The version of beamer I'm using, as described in the
repositories, is latex-beamer 3.07-2ubuntu1. I am aware  that there are more
recent versions available  - particularly of org-mode - but was trying to keep
things simple.

Let me also say that my aim was to arrive at an understanding of  how to use
org-mode for slide creation - since I do a lot of that - rather than to compose
a specific set of slides. I realise that I could use direct latex code to solve
the problems but that wasn't the point of the exercise.

I've read more since I sent the email and now realise that the issues I brought
up have been discussed earlier and where I can I've tried to use the proposed
solutions. In particular I have this in my .emacs:

(setq org-emphasis-alist (quote (("*" bold "<b>" "</b>")
("/" italic "<i>" "</i>")
("_" underline "<span
style=\"text-decoration:underline;\">" "</span>")
("=" org-code "<code>" "</code>" verbatim)
("~" org-verbatim "<code>" "</code>" verbatim)
("+" (:strike-through t) "<del>" "</del>")
("@" org-warning "<b>" "</b>")))
org-export-latex-emphasis-alist (quote
(("*" "\\textbf{%s}" nil)
("/" "\\emph{%s}" nil)
("_" "\\underline{%s}" nil)
("+" "\\texttt{%s}" nil)
("=" "\\verb=%s=" nil)
("~" "\\verb~%s~" t)
)

from a solution to the @ problem proposed by Eric somewhere. And I understand
that I can use \maketitle normally to produce a title page in beamer - just
tried on a hand-crafted (in emacs)  latex-beamer file using my set up.

To keep this email as brief as possible, let's take this snippet (verbatim) of
an  example from Eric:

* Methodology

** A simple slide
This slide consists of some text with a number of bullet points:
- the first, very @important@, point!
- the previous point shows the use of the special markup which
translates to the Beamer specific /alert/ command for highlighting
text.
The above list could be numbered or any other type of list and may
include sub-lists.
---------------------------end----------------------------------------

When I do "C-c C-e p" to create the pdf file I get 3 slides. The first is a
title page but has no title - only the date. The second is an outline (toc)
slide as expected and the third is again as expected except that @important@ is

The latex created  by "C-c C-e l" is

and running pdflatex on this produces an identical result to "C-c C-e p" on the
org file - as it should.

I'm not sure I've answered all of your questions but perhaps this is enough to
suggest a solution or refine the questions.
