Hi Dan & Eric,
Again (and now on-list), thanks a lot for your reply and your help!

Yes, syntax highlighting seems to be work as expected.

That also works.
I only have a very (very) basic knowledge of elips. So, I guess it is
possible to change the "depth" of indentation. The current indentation
behaviour is as follows:
#+BEGIN_SRC R :results output :exports results
library(MASS)
plot(1,1)
for(i in 1:10){
print(i)
}
[...]
However, I would prefer...
#+BEGIN_SRC R :results output :exports results
library(MASS)
plot(1,1)
for(i in 1:10){
print(i)
}
[...]

Puh, as I told you I only have a very basic understanding of elisp... If
I do a simple copy and paste, I see this error: "Symbol's value as
variable is void: org-mode-map". I also guess that I should change
"dan/org-underscore-command"...
However, you should not care about my little elips problems. You were
really helpful in solving my most important problems!
Thanks,
Bernd
