Newbie - How to end plain list?

[Marco Alberti <m.alberti@fct.unl.pt>]

Dear Org users,
I have been using Org for a few days and loving it.
Now I am stuck on a little problem that probably has an obvious  
solution that I'm missing. Suppose I want to type this note:

* Section title
   Some plain text.
   - One item
   - One more item
   Back to plain text.

If the cursor is at the end of the second item line, is there a  
command to resume the plain text indentation on the new line? Return  
and TAB place the cursor below the "O" in the second item line, and  
from there the best I came up with is to backspace twice. I would  
expect some "structure-aware" command, but I couldn't find one.

I am using Aquamacs on Mac OS X. I also tried Emacs 23 on Windows and  
I see no difference.

Thanks,
Marco
