I include citations in the titles of slides and I would like the citations to be right justified (fully) while the title itself is left justified. I used
<title-text> \hfill <\cite{}>
but this does not push the citation to make it right-justified; it simply moves the citation a bit to the right as shown in the following figure. Is there any way to make the citation right-justified?
Thanks.

\vskip0pt plus 1filll. Perhaps it will work for you if you change\vskip0ptto\hskip0ptand then use the entire bit instead of\hfill. (I haven't tried it.) – Michael S Taylor Aug 23 '14 at 03:18
