 There are a number of commands that can be used to specify what effect should be used when the current slide is presented. Consider the following example:
 \begin{verbatim}
-\frame{\pgfuseimage{youngboy}}
-\frame{
+\begin{frame}
+  \pgfuseimage{youngboy}
+\end{frame}
+\begin{frame}
   \transdissolve
   \pgfuseimage{man}
-}
+\end{frame}
 \end{verbatim}
 The command |\transdissolve| causes the slide of the second frame to be shown in a ``dissolved way.'' Note that the dissolving is a property of the second frame, not of the first one. We could have placed the command anywhere on the frame.

   \beamernote
   If you use a professional font package, \beamer's internal redefinition of how variables are typeset may interfere with the font package's superior way of typesetting them. In this case, you should use the class option |professionalfonts| to suppress any font substitution. See Section~\ref{section-substition} for details.

-  This font theme does not really change any fonts. Rather, it \emph{suppresses} certain internal replacements performed by \beamer. If you use ``professional fonts'' (fonts that you buy and that come with a complete set of every symbol in all modes), you do not want \beamer\ to meddle with the fonts you use. \beamer\ normally replaces certain character glyphs in mathematical text by more appropriate versions. For example, \beamer\ will normally replace glyphs such that the italic characters from the main font are used for variables in mathematical text. If your professional font package takes care of this already, \beamer's meddling should be switched off. Note that \beamer's substitution is automatically turned off if one of the following packages is loaded: |arevmath|, |hvmath|, |kpfonts|, |lmodern|, |lucidabr|, |lucimatx|, |mathastext|, |mathpmnt|, |mathpple|, |mathtime|, |mtpro|, and |mtpro2|. It is also turned off when |unicode-math| is loaded for the use of Unicode math fonts. If your favorite professional font package is not among these, use the |professionalfonts| option (and write us an email, so that the package can be added).

 \section{Introduction}
 
-\beamer\ is a \LaTeX\ class for creating presentations that are held using a projector, but it can also be used to create transparency slides. Preparing presentations with \beamer\ is different from preparing them with \textsc{wysiwyg} programs like OpenOffice.org Impress, Apple Keynote, KOffice KPresenter or Microsoft PowerPoint. A \beamer\ presentation is created like any other \LaTeX\ document: It has a preamble and a body, the body contains |\section|s and |\subsection|s, the different slides (called \emph{frames} in \beamer) are put in environments, they are structured using |itemize| and |enumerate| environments, and so on. The obvious disadvantage of this approach is that you have to know \LaTeX\ in order to use \beamer. The advantage is that if you know \LaTeX, you can use your knowledge of \LaTeX\ also when creating a presentation, not only when writing papers.

 \subsection{Specifying Note Contents}
 
-To add a note to a slide or a frame, use the |\note| command. This command can be used both inside and outside frames, but it has quite different behaviors then: Inside frames, |\note| commands accumulate and append a single note page after the current slide; outside frames each |\note| directly inserts a single note page with the given parameter as contents. Using the |\note| command inside frames is usually preferably over using them outside, since only commands issued inside frames profit from the class option |onlyslideswithnotes|, see below.

Using the |\note| command inside frames is usually preferably over using them outside, since only commands issued inside frames profit from the option |show only slides with notes|.
 
 Inside a frame, the effect of |\note|\meta{text} is the following: When you use it somewhere inside the frame on a specific slide, a note page is created after the slide, containing the \meta{text}. Since you can add an overlay specification to the |\note| command, you can specify after which slide the note should be shown. If you use multiple |\note| commands on one slide, they ``accumulate'' and are all shown on the same note.
