cmd-return in editor does not go to next line

I can see the benefit of single stepping in some cases, but I
wouldn't want to lose the current behaviour.

Whiile on the subject, cmd-return has an odd feature. Once a line has
been submitted using cmd-return, it needs two returns not one to move
from the end of the line to the next. I suspect this is not intended
- can it be changed?

Thanks,
Tim

 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.

In Aquamacs, I most often use C-c C-n; this submits a line and step
to next. I like it because I can keep my left pinkie finger on the
Crtl key to execute it. (I am not much of a typist).
