Hi,
I've put together a first pass at such support for interactive header
argument look up. Please evaluate this elisp code [1] in your *scratch*
buffer, then in an Org-mode buffer insert a code block like the
following with the point at [*], and press tab.
#+begin_src R :[*]
:foo
#+end_src
You should see an auto-completion list showing which header arguments
are available and (for those with known arguments) which arguments may
be specified. This includes language specific header arguments, i.e.,
the R code block above suggests about twice as many possible header
arguments as an elisp block. Note this "expand on tab after :" behavior
is active on "#+headers:" lines as well.
This makes use of the `org-babel-common-header-args-w-values' variable
which holds header argument names and completions, as well as the
org-babel-header-arg-names:lang variables.
Does this seem like a good interface?
Is it missing any important functionality?
Best,
Footnotes:

lang-headers))
