Keybaord shortcut for moving rows of text from one line to another

When I was using Poerpoint on the PC, I was able to select a row of
text and use a keyboard shortcut (OPTION CTRL- UP/DOWN ARROW?) to move
the entire row up or down a row. I believe you can do the same in
Word.  I can't seem to find it in PPT in Office 2008.  Is it avaialble
and, if not, is there a AppleScript macro for this function?

Thanks,
John
