[scribus] Positioning Text at Both Line Margins

[Rich Shepard]

   Looking at the wiki and manual I have not found how to add a horizontal
fill space so two text blocks are justified at the margins.

   Specifically, I want a text box to have a couple of words left justified
and another couple of words right justified with blank space between them.
In LaTeX the command is \hfill{}; how do I do this with scribus?
