I just started using Emacs/ESS for R and like what I'm seeing so far (and it
just feels comforting, even though I'm just relearning emacs after 10 years
away, to be using emacs). I am aware of using C-x C-<arrow> to switch
between open buffers. When executing R code in interactive mode, there is a
2 way split screen with Active Buffer / R console.

1. Is there a kb shortcut to move the kb focus to the R buffer and back?
(see attached screenshot) http://tinypic.com/r/rjicrk/7
2. Is it possible to have a vertically split buffer?
3. Is possible to have a 2 column window where left column has 1 buffer (R
source file), right column has a horizontal split with one being R console
and the other being a call tip window or an object explorer?

Thanks!
