Thanks for the pointer! I have already seen that thread, for I started 
it:) But that actually doesn't answer the question, as you pointed out 
later.

But I think, Alt+Enter for the specific functionality that I described, 
should not be a problem. After all, no characters are tied to Alt+Enter. 
Perhaps, I should make myself clear: I am not advocating the idea that 
the present set of shortcuts should be changed, I am just trying to see, 
how a new shortcut could be accommodated. I would also like to point out 
that this discussion also pertains to another one, 
http://mail.scipy.org/pipermail/ipython-user/2012-June/010517.html, 
although, in that case, it is somewhat clearer what the combination 
could be, it is just not clear, how it should be implemented.

So, should I just try to add Alt+Enter as a new keybinding for executing 
a cell, and inserting a new cell code in place?
Cheers,
Zoltán
