Why do you want to see you code? The point jumps to the end of submitted
region for all "& step" commands. And ess-eval-region (C-c C-r) sends the
region which is already selected. So in both cases it's quite clear what you
send.

Everything in ESS what evaluates visibly is very slow. It send each line and
wait for it to actually appear at the R prompt. So there is no way for it to
be made faster.

By the way, this is so frequently asked question that I believe it's worth
starting ESS FAQ just for it alone:)

In my impression this is very slow even for commands with low calculation demands (e.g. defining functions etc.) compared to other GUIs that I have so far tested (Rkward, Standard R-GUI). Does anyone of you experience similar issues? Or does anybody have an idea on where to search for hints to the problem?
