Sorry, may be the title is not clear. In fact, I need to make a list of advantages and disadvantages and I want to note the advantages as + and disadvantages as -. How can I change the full circle of item to + or - sign?

 \documentclass[compress,red]{beamer}
 \usepackage{etex}
 \mode<presentation>
 \usetheme{Warsaw}
   \usepackage[applemac]{inputenc}%les accents pour mac
   \usepackage{subfigure}
  \usepackage{amsmath}
  \usepackage{epsfig} 
     \usepackage{graphicx}
   \usepackage[all,knot]{xy}
    \xyoption{arc}
   \usepackage{setspace}
     \begin{document}
      \section{section1 }
     \frame[shrink]{\frametitle{Titre de la fenetre}
     \begin{itemize}

         \item point1
        \item point2
       \item point3
        \item point4
        \item point5
       \end{itemize}

        }

  • \item[+] is what you want?

  • @Sigur, thanks, yes I resolve it. sorry, if the question is evident. I can delete it. Nov 15, 2013 at 16:18
  • You can test other variants, using math symbols as optional argument. For example, \item[$-$] is different from \item[-] and from \item[--].

Just an addition to @Sigur's answer. You can define macros, say \pro and \con,

\newcommand\pro{\item[$+$]}
\newcommand\con{\item[$-$]}

to save some repetitive typing, and make the source code more readable.

MWE

\documentclass{beamer}
\usetheme{Warsaw}
\begin{document}

\newcommand\pro{\item[$+$]}
\newcommand\con{\item[$-$]}

\frame{
    \begin{itemize}
        \pro advantage
        \con disadvantage
        \item neutral
    \end{itemize}
}

\end{document}

Output

As Sigur commented, you can use the optional argument to \item to specify the bullet:

\item[+] Some positive point
\item[$-$] Some negative point %use $-$ instead of - for a real minus sign.
\item Some neutral point

enter image description here

In my opinion the minus sign isn't great for this (not very clear), but you can use almost anything for your bullet, including colour commands (e.g. \item[\textcolor{red}{-}]). The comprehensive LaTeX symbols list may help you to find something good, such as \oplus and \ominus (circled versions, normally used as binary operators) from the mathabx package.

EDIT: code updated thanks to comment from Przemysław Scherwentke, but I can't easily updated the image from here.

    Only not \item[-] but \item[$-$] if it should be a minus sign. Nov 15, 2013 at 17:09
  • @PrzemysławScherwentke, I've updated the code, will do the image tomorrow if I remember.

You can use

\usepackage{paralist}

with

\begin{compactitem}[-]
\item
\end{compactitem}

and any optional argument at [] to to specify the bullet.

\begin{enumerate}[(i)][8] or \begin{compactitem}[$\circ$] or

have a look at paralist

Additional pro: save space with compactitem
