Emacs does this for emacs-lisp, so....
(anyway, I've got a preliminary version of what John A. suggested --
it brings up the results of "args" in a separate buffer. Just need to
format, etc, so that it'll be a "fill in the blanks".
M-x ess-dump-args-and-go
in the next version of ESS).
The other paradigm that would be nice would be like what PSGML mode
does for XML/SGML/HTML -- C-c C-a brings up a window for the tag
attributes. This might be more like what John wants, where you can
use [tab] to move between fields, and defaults are specified. For
this, I'd need a much better discovery mechanism than args().
