# How to edit footnote in LyX

Is it be possible to edit the footnote of the title of the presentation? I want to edit the author name (because by default it comes with department name) and title of the presentation (because it is quite large). Can it be different from the main title?

Please always add to your questions a minimal version of your code showing the relevant settings. – Gonzalo Medina Nov 21 '11 at 17:50
I am not using any coding. Just using LYX. – biostat Nov 21 '11 at 17:59
Ah... I didn't know that LyX doesn't produce code. – Gonzalo Medina Nov 21 '11 at 18:00
Your thoughts betray you @biostat. I feel the good in you, the conflict. Come over to the LaTeX side of the force. – qubyte Nov 21 '11 at 18:12
Also, LyX does produce code. Maybe it's in a container, but the code is there. Otherwise it wouldn't be LaTeX. Anyway, I used to collaborate with a guy who used LyX. It produces horrible code. – qubyte Nov 21 '11 at 18:13

To suppress the parentheses, you can (re)define the footline beamer template (as defined in the outer theme infolines which is internally used by Madrid); for your other question, you can use the optional argument of \title:

\documentclass{beamer}
% Add to preamble from here ------------------
\usetheme[secheader]{Madrid}

\makeatletter
\setbeamertemplate{footline}
{
\leavevmode%
\hbox{%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{author in head/foot}%
\usebeamerfont{author in head/foot}\insertshortauthor%~~\beamer@ifempty{\insertshortinstitute}{}{(\insertshortinstitute)}
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,center]{title in head/foot}%
\usebeamerfont{title in head/foot}\insertshorttitle
\end{beamercolorbox}%
\begin{beamercolorbox}[wd=.333333\paperwidth,ht=2.25ex,dp=1ex,right]{date in head/foot}%
\usebeamerfont{date in head/foot}\insertshortdate{}\hspace*{2em}
\insertframenumber{} / \inserttotalframenumber\hspace*{2ex}
\end{beamercolorbox}}%
\vskip0pt%
}
\makeatother
% To here ----------------------

\author{A.U. Thor}
\title[The Title in footline]{The Title in the document}
\institute{The Institute}

\begin{document}

\begin{frame}\maketitle\end{frame}
\section{Test section}
\subsection{Test subsection one}
\begin{frame}\frametitle{adafdg}Test\end{frame}
\subsection{Test subsection two}
\begin{frame}Test\end{frame}

\end{document}


EDIT: This is the whole code for a LaTeX user, so just include the marked part in your LyX preamble

should I put this text in LYX peamable? – biostat Nov 21 '11 at 17:54
@biostat: I guess so; I've never used LyX. – Gonzalo Medina Nov 21 '11 at 17:55
include everything from \usetheme... to \makeatother in your preamble. The rest is created by you in your main document. – chwi Oct 22 '12 at 13:45
