In Lyx, section Acknowledgments, I need to change the title displayed as "Acknowledgements" in the pdf. How can I do that ?

    Hi, welcome to TeX.SX. Can you describe how you add this Acknowledgement, does it come from a module, or a (non-standard) document class? Aug 14, 2013 at 21:41
  • I am using a package that translates in my own language. But anyway it displays "Acknowledgements" in the pdf (not under Lyx, where it is written: "remerciements". I am not asking for a way to permanently change the translation, just a way to have control on the characters sequence "Acknowledgement", to modify it in my document.

  • Which package? Which document class are you using? How exactly do you add these acknowledgements? We really need more details to be able to answer your question. Aug 14, 2013 at 22:14
  • Sorry, I am new to Lyx, I used the default package of Lyx for French language (I dont know its name), for the class it is article(revtex4), for the Aknowledgements, I simply select Acknowledgements (it appears in French) in the Environment box

  • No worries. Knowing the document class is sometimes necessary, and very much in this case, as it is that which defines the Acknowledgements environment. Aug 14, 2013 at 22:47

To change this, go to Document --> Settings --> LaTeX Preamble, and add


Or change Remerciements to whatever you like.

This is one of many such definitions made in revtex4.cls, in the lines 5878 to 5911 (may others as well, I haven't checked). Here you'll also find \def\tocname{Contents}, so to change Contents into something else, \renewcommand\tocname{Something else}. Below is a copy the above mentioned lines:

  January\or February\or March\or April\or May\or June\or
  July\or August\or September\or October\or November\or December\fi
  \space\number\day, \number\year}
\def\lofname{List of Figures}
\def\lotname{List of Tables}
\def\@pacs@name{PACS numbers: }%
\def\@keys@name{Keywords: }%
\def\Dated@name{Dated: }%
\def\Received@name{Received }%
\def\Revised@name{Revised }%
\def\Accepted@name{Accepted }%
\def\Published@name{Published }%

Note that for the standard classes, these are changed by babel (the standard language package used by LyX), and if you want to change them into something else, see Translate paragraph environment

  • Thanks, I need the same for the "Contents" title: something like \renewcommand\contentsname{Contents} does not work (I get an error: "contentsname not defined").
