I've just started using R 2.62 on OSX 10.4.11 on a macbook 2,1 and
found that in the Editor on Windows ctrl-R runs the current line and
goes to the next line. On Mac cmd-return runs the current line and
stays there. Shouldn't the cursor go to the next line, so a program
can be run stepwise with multiple cmd-rtn instead of cmd-rtn down-
arrow?

It was not designed to do so, but clearly it could be changed,  I'm
not sure it's good idea, though, as it combines an action (execute a
line) with a change of selection and that is usually not desirable (I
know that WIndows is known to breach UI design principles all over  
the
place, but that's another story). Most commonly one uses selection to
select the program/function that will be run instead and you don't
want to change the position there. Any comments on this from other
users?

In Windows the mental image is that there are two functions attached  
to
Ctrl-R:

- if something is selected, then submit it.
- if not, then single step through the script.

The second function is what Rune is asking about.  I'd say it's good  
to
have a "single step" function on a key.  It doesn't need to be the  
same
key as "submit the selection", but it doesn't seem to lead to  
confusion
if it is.

On a Mac in the Xcode debugger, what's the key for single stepping?   
(My
Mac is at home, I can't check.)  It would make a lot of sense to use
that key for single stepping in the script editor too.

Is there a search option in the web archive? I couldn't find it.
