Centering List of X and Following with Text

Question

With the tocloft package, I can add text under the title of a "List of Z" at the beginning of a latex document:

\renewcommand{\cftafterZtitle}{\par\noindent \textnormal{Z} \hfill \textnormal{PAGE}}

Using the following I can center the title "List of Z":

\renewcommand{\cftZtitlefont}{\hfill\bfseries}
\renewcommand{\cftafterZtitle}{\hfill}

But when I try to combine the two commands, it moves the text to the right margin instead of the center:

\renewcommand{\cftloftitlefont}{\hfill\bfseries}
\renewcommand{\cftafterloftitle}{\hfill\par\noindent \textnormal{Z} \hfill \textnormal{PAGE}}

Does anyone know how to both center the title "List of Z" and have text below the title?

Answer 1

You can add an empty \hbox after the second \hfill (See egreg's answer to What is \null and when do we need to use it?):

\documentclass{article}
\usepackage{tocloft}

\renewcommand{\cftloftitlefont}{\hfill\bfseries}
\renewcommand{\cftafterloftitle}{\hfill\null\par\noindent\textnormal{Z}\hfill \textnormal{PAGE}}

\begin{document}

\listoffigures

\noindent X\hrulefill Y% for coparison only

\end{document}

Another option is to use \hfil instead:

\renewcommand{\cftloftitlefont}{\hfil\bfseries}
\renewcommand{\cftafterloftitle}{\hfil\par\textnormal{Z}\hfill \textnormal{PAGE}}
