I haven’t ever used rmail, but Gnus has a pair of functions
gnus-summary-select-article-buffer and gnus-article-show-summary, bound
to h in gnus-summary-mode-map and gnus-article-mode-map respectively,
which allow conveniently switching between the summary buffer and the
message buffer.

I think Xavier is looking for a similar pair of functions for rmail, as
opposed to having to use the general other-window bound to C-x o.
