+\section{Purposes}
+\begin{frame}[<+->]{Purpose of the Beamer class}
+
+With the \structure{Beamer} class, you can produce presentation slides,
+which
+\begin{itemize}
+\item are visually highly customizable
+\item can be very well structured
+\item can be constructed step-by-step (``overlay'' concept)
+\item may contain different navigation paths (note that the slides contain
+all sorts of hyperlinks)
+\item use \LaTeX 's superb output quality
+\item might embed multimedia content (audio, video)
+\item can easily be transformed to accompanying material (such as an article-like
+handout)
+\item and much more \ldots{}
+\end{itemize}
+\end{frame}
+%
+\begin{frame}{Purpose of this presentation}
+
+This presentation
+\begin{itemize}
+\item describes some basic features of \structure{Beamer}
+\item especially how they can be used with \LyX{}
+\end{itemize}
+For more general and comprehensive information on \structure{Beamer}
+itself, please refer to the extensive class manual \cite{beamer-ug}
+\end{frame}
+%
+
+\section{Segments of a presentation}
+\begin{frame}{The global structure}
+
+A presentation usually consists of
+\begin{itemize}
+\item a title page
+\item slides that might be grouped to sections/parts
+\item an appendix with additional information, such as a bibliography
+\end{itemize}
+We describe these global segments in what follows.
+\end{frame}
+%
+\begin{frame}{The title page}
+
+Within \LyX , a title page is constructed by the layouts \structure{Title},
+\structure{Subtitle}, \structure{Author}, \structure{Institute},
+\structure{Date} and \structure{TitleGraphic}.
+\begin{itemize}
+\item None of these elements is mandatory, but at least one must be given
+\item The order of insertion does not matter (the real order is defined
+in the \structure{Beamer} theme)
+\item For \structure{Title}, \structure{Subtitle}, \structure{Author},
+\structure{Institute} and \structure{Date}, you can define ``short''
+forms via \alert{Insert\lyxarrow Short Title\slash Date\slash\ldots}
+These are used in the sidebar\slash heading (given the theme actually
+provides a sidebar\slash heading)
+\item If you select \structure{Title (Plain Frame)} instead of \structure{Title},
+the title page will have no sidebar or heading
+\end{itemize}
+\end{frame}
+%
+\begin{frame}{Slides/Frames}
+
+Slides are called ``frames'' in \structure{Beamer}. Everything
+inside a frame is put on one slide (which itself might consist of
+sub-slides).
+\begin{itemize}
+\item Select the \structure{Frame} style to start a frame
+\item The frame title is to be inserted in the ``Frame title'' inset,
+which is automatically inserted for new frames or can be manually
+inserted via \alert{Insert\lyxarrow Frame Title}
+\item Alternatively, you can also use the \structure{FrameTitle} layout,
+which additionally offers a (rarely used) short frame title option,
+and, more importantly, overlay options
+\item A subtitle can be added via the \structure{FrameSubtitle} layout
+\item Frame options (see \cite{beamer-ug} for the diverse options) are
+inserted via \alert{Insert\lyxarrow Frame Options}, overlay options
+via \alert{Insert\lyxarrow Overlay Specifications} and \alert{Insert\lyxarrow Default Overlay Specifications}
+(we explain later what this is)
+\end{itemize}
+\end{frame}
+%
+\begin{frame}<1-2>[label=myframe]{Frames can be repeated}
+
+Frames can be repeated fully or only in terms of selected sub-slides,
+multiple times at any later point of the presentation.
+
+You just need to give the respective frame a label name via the frame
+option ``label'' (as done here).
+
+\pause{}
+
+Then you can repeat this frame by means of the \structure{AgainFrame}
+layout later in the presentation. Just enter the label name in the
+\structure{AgainFrame} layout and specify, if required, which sub-slides
+you want to be repeated via \alert{Insert\lyxarrow Overlay Specifications}
+(again, see below for the concept of ``overlays'').
+\begin{proof}<3>
+\alert{Here's the proof!} (This text is only shown on sub-slide
+3 which is itself only shown when this frame is repeated later on)
+\end{proof}
+
+\end{frame}
+%
+\begin{frame}{Keeping frames together}
+
+\framesubtitle{Use nesting!}
+\begin{itemize}
+\item Note that all frame content, if the style is not \structure{Frame},
+must be nested to the frame environment (via \alert{Edit\lyxarrow Increase List Depth}
+or \shortcut{Alt+Shift+Right}). This is done automatically if you
+insert new frame paragraphs.
+\item Nested content is marked by a red bar in the margin of the \LyX{} workarea
+\end{itemize}
+\end{frame}
+\begin{itemize}
+\item Non-nested content (such as this) will also be displayed in the presentation
+(on a separate slide), but not properly aligned
+\item So please avoid this
+\end{itemize}
+%
+\begin{frame}{Separating frames}
+
+\noindent Consecutive frames have to be separated from each other.
+This is done by means of the \structure{Separator} inset, which can
+be produced by hitting return in an empty Standard paragraph right
+below the frame (see UserGuide, sec.~3.4.6).
+\begin{block}{Tip}
+
+There is a simple and much more convenient way to start a new frame:
+Issue \alert{Insert\lyxarrow Separated Frame Below} (\shortcut{undefined}
+if you are in a non-nested \structure{Frame} paragraph, or \shortcut{Alt+P Shift+Return},
+respectively, if you are in a nested paragraph within the frame).
+If you are in the frame heading, \alert{Insert\lyxarrow Separated Frame Above}
+inserts a new, properly separated frame above the current one!
+\end{block}
+\end{frame}
+%
+
+\againframe<3>{myframe}
+
+\begin{frame}[plain]{Special frame types}
+
+\LyX{} provides two special frame types:
+\begin{enumerate}
+\item \structure{Frame (plain)} is a frame without a sidebar/header (such
+as this one). This is useful for slides with much content\slash wide
+tables
+\item \structure{Frame (fragile)} is to be used if the frame consists of
+``fragile'' content, especially verbatim stuff such as program listings
+\end{enumerate}
+If you want a fragile plain frame, pass the option ``plain'' to
+a fragile frame or the option ``fragile'' to a plain frame.
+\end{frame}
+%
+\begin{frame}{Sectioning a presentation}
+\begin{itemize}
+\item To group frames, you can use the usual sectioning commands (\structure{Section},
+\structure{Subsection} etc.)
+\item These are shown in the table of contents, the sidebar\slash header
+(depending on the theme) and the article output (for ``article''
+see below, the section on ``modes'')
+\end{itemize}
+\end{frame}
+%
+\begin{frame}{Parts have special meaning}
+\begin{itemize}
+\item You can also divide your presentation into \structure{Parts}. Note,
+however, that parts behave differently in \structure{Beamer} than
+in other document classes: a part is considered to be ``a little
+`talk of its own' with its own table of contents, its own navigation
+bars, and so on.'' \cite[sec.~10.3]{beamer-ug}
+\item This means, for instance, that if you use parts, the table of contents
+will only list the sections and subsections of the part that contains
+this table of contents, and the sidebar\slash header will also only
+show the sections of the current part.
+\end{itemize}
+\end{frame}
+%
+\begin{frame}{Re-arranging frames}
+\begin{block}{Tip}
+
+Did you know that you can easily move and re-arrange whole frames
+via the outliner (\alert{View\lyxarrow Outline Pane})?
+
+Also, you can navigate to a specific frame via the \alert{Navigate}
+menu!
+\end{block}
+\end{frame}
+%
+\begin{frame}{The appendix}
+\begin{itemize}
+\item Appendices might be useful for additional\slash reserve material.
+The appendix is part of the presentation, but not shown in the table
+of contents\slash sidebar\slash header
+\item An appendix is inserted as usual in \LyX :
+\begin{itemize}
+\item Use \alert{Document\lyxarrow Start Appendix Here} at the position
+where the appendix should begin
+\end{itemize}
+\item Typical content of the appendix is the bibliography
+\begin{itemize}
+\item You insert it as in all other \LyX{} classes, via the \structure{Bibliography}
+style (see the bibliography at the end of this presentation as an
+example)
+\item Note that you can also use Bib\TeX , although not all Bib\TeX{} styles
+are prepared to work with \structure{Beamer}
+\end{itemize}
+\end{itemize}
+\end{frame}
+%
+
+\section{The overlay concept}
+\begin{frame}{What are overlays?}
+
+Basically, the overlay concept allows to change the slide content
+dynamically. You can uncover things/text piecewise, fade out content,
+highlight things, replace text, images etc.
+
+\pause{}
+\begin{itemize}[<+->]
+\item Overlays are useful to build up slides as you speak
+\item They help you to shift your audience's focus on specific things
+\item And they help your audience to follow you
+\item So use overlays! \alert<6>{Really, use them!}
+\end{itemize}
+\end{frame}
+%
+\begin{frame}{Overlay types}
+
+\structure{Beamer} provides many different overlay types. The most
+important ones are:
+\begin{description}
+\item [{Hidden~content:}] Stuff that is completely invisible up to a point
+\item [{Covered~content:}] Stuff that is faded out (not completely invisible)
+\item [{Highlighted~content:}] Stuff that is somehow emphasized at a certain
+point
+\end{description}
+We give examples for these types in what follows, but begin with some
+general remarks on overlay possibilities
+\end{frame}
+%
+\begin{frame}{General overlay/action possibilities}
+
+Many \structure{Beamer} elements provide overlay settings. Basically,
+you can define on which sub-slide(s) a given content appears (``2'',
+``2-4'', ``3-'', ``1,3'' etc.), or in which output mode (``presentation'',
+``article'' etc.)
+\begin{itemize}
+\item In \LyX , these settings are generally accessible via \alert{Insert\lyxarrow Overlay Specifications}
+or \alert{Insert\lyxarrow Action Specifications}
+\end{itemize}
+\begin{overprint}
+\onslide<2>
+\begin{definition}
+``Action'' is a more general concept, which does not only include
+what we have called ``overlays'' (``on which sub-slide{[}s{]} is
+this to be shown\slash hidden\slash highlighted''), but also tasks
+such as ``only show this in the presentation, not on the handout''
+or ``show this on the second screen only'' (so-called ``modes'').
+\end{definition}
+
+\onslide<3>
+\begin{alertblock}{Note to the \LaTeX{} aficionados}
+
+The mentioned overlay/action settings conform to those command/environment
+options embraced by\alert{\ <\ldots >} and \alert{{[}<\ldots >{]}}
+in the \LaTeX{} output.
+
+Note that \LyX{} adds those braces on export, so you must not enter
+them yourself. In other words, enter ``1'' or ``+-'' to the overlay/action
+insets, not ``<1>'' or ``{[}<+->{]}''!
+\end{alertblock}
+\end{overprint}
+\end{frame}
+%
+\begin{frame}{An example}
+
+Take for example a quote. In a \structure{Quote} environment, you
+can specify the overlay settings via \alert{Insert\lyxarrow Overlay Specifications}.
+If you do this and enter ``2'', the quote will only appear on (sub-)slide
+2:
+\begin{quote}<2>
+Fear no more the heat o\textquoteright{} the sun
+
+Nor the furious winter\textquoteright s rages
+
+Thou thy worldly task hast done
+
+Home art gone, and ta\textquoteright en thy wages
+\end{quote}
+This is how the concept works, basically.
+\end{frame}
+%
+\begin{frame}{Covering vs. hiding}
+
+The difference between ``covering'' and ``hiding'' is that hidden
+content is treated as if it isn't there, while covered content is
+just covered (and the space is reserved). If we would have hidden
+the quote on the last slide and not covered, it would only have taken
+space on appearance:
+\begin{quote}<only at 2>
+Fear no more the heat o\textquoteright{} the sun
+
+Nor the furious winter\textquoteright s rages
+
+Thou thy worldly task hast done
+
+Home art gone, and ta\textquoteright en thy wages
+\end{quote}
+
+You can see how this text moves when the quote is un-hidden.
+\end{frame}
+%
+\begin{frame}{Coverage degrees}
+
+\setbeamercovered{transparent}
+
+\structure{Beamer} offers several degrees of ``coverage'', which
+can be set via the command \alert{\textbackslash setbeamercovered}
+either globally (for the whole presentation) or locally (e.\,g. for
+a single frame, as here). By default, content is completely covered.
+In ``transparent'' mode, you can see covered text greyed-out:
+\begin{quote}<2>
+Fear no more the heat o\textquoteright{} the sun
+
+Nor the furious winter\textquoteright s rages
+
+Thou thy worldly task hast done
+
+Home art gone, and ta\textquoteright en thy wages
+\end{quote}
+Check the \structure{Beamer} manual for more possibilities.
+\end{frame}
+%
+\begin{frame}{Default overlay/action specifications vs.\\
+(normal) overlay/action specifications}
+\begin{itemize}
+\item For some environments (such as lists and also frames), you can set
+``default specifications'' additionally to normal overlay/action
+specifications (or in the case of lists: ``overlay specifications''
+for the whole list and ``item overlay specifications'' for singular
+items)
+\item Default specifications apply to all content of the given environment,
+if not individually specified otherwise
+\item They use a placeholder syntax. E.\,g., ``+(1)-'' will uncover all
+items in a list step by step (with a start offset of 1) if they have
+no individual item specification:
+\begin{itemize}[<+(1)->]
+\item One
+\item Two
+\item Three
+\item<1-> Always
+\end{itemize}
+\end{itemize}
+Please consult the \structure{Beamer} manual for details on this
+syntax.
+
+\end{frame}
+%
+\begin{frame}[<+->]{Default overlay/action specifications vs.\\
+(normal) overlay/action specifications}
+
+\noindent This frame uses a specific default overlay specification
+
+which causes each overlay-aware paragraph \ldots{}
+\begin{itemize}
+\item \ldots{} or list item \ldots{}
+\item \ldots{} to appear \ldots{}
+\item \ldots{} on a subsequent sub-slide \ldots{}
+\end{itemize}
+\begin{block}{A block}
+
+\ldots{} one after the other
+\end{block}
+\end{frame}
+%
+\begin{frame}[<alert at +>]{Default overlay/action specifications vs.\\
+(normal) overlay/action specifications}
+
+\noindent And this frame uses a specific default overlay specification
+\ldots{}
+\begin{itemize}
+\item \ldots{} which causes each overlay-aware list item \ldots{}
+\item \ldots{} to be highlighted \ldots{}
+\item \ldots{} on respective sub-slides
+\end{itemize}
+\end{frame}
+%
+\begin{frame}{Pause}
+
+The \structure{Pause} layout lets you mark a point where all following
+content will be covered (by default for one slide, with regard to
+the content preceding the pause):
+
+\pause{}
+
+After first pause
+
+\pause{}
+
+After second pause
+
+\pause[2]{}
+
+By default, consecutive pauses also end consecutively.
+
+Via \alert{Insert\lyxarrow Pause Number}, however, you can specify
+a specific sub-slide at which the given pause ends, independent from
+the number of pauses inserted before this one.
+\end{frame}
+%
+\begin{frame}{Paragraph-wide overlays}
+
+\structure{Beamer} and \LyX{} provide you with paragraph layouts whose
+purpose it is to show/hide whole paragraphs or sequences of paragraphs
+on specific slides. These are particularly:
+\begin{uncoverenv}<2->
+
+The \structure{Uncovered} layout which uncovers all content on the
+specified slides \ldots{}
+\begin{itemize}
+\item \ldots{} including nested paragraphs of other layout.
+\end{itemize}
+\end{uncoverenv}
+
+\begin{onlyenv}<3->
+
+The \structure{Only} layout which un-hides content (note again how
+the surrounding text ``moves'' when this gets visible).
+\end{onlyenv}
+
+\begin{overprint}
+\onslide<4>
+
+And the \structure{Overprint} environment which lets you enter \ldots{}
+\onslide<5>
+
+\ldots{} alternative text taking a specific space on specified slides.
+
+\end{overprint}
+as demonstrated here.
+\end{frame}
+%
+\begin{frame}{Inline overlays}
+
+\setbeamercovered{transparent}
+
+\structure{Beamer} also supports inline overlays for text parts (as
+opposed to whole paragraphs), which are accessible via \alert{Edit\lyxarrow Text Style}
+in \LyX :
+\begin{itemize}
+\item You can \structure{uncover} \uncover<2->{text} on specific slides
+\item You can make \visible<3->{text} \structure{visible} (which makes
+a difference to ``uncover'' only with ``transparent'' coverage
+setting, as used locally on this slide)
+\item You can show \only<4->{text }\structure{only} on specific slides
+\item You can make \invisible<5->{text} \structure{invisible}
+\item And you can show \alt<6->{different}{\structure{alternative}} text
+\end{itemize}
+As for the paragraph layouts, the overlay settings can be accessed
+via the \alert{Insert} menu.
+\end{frame}
+%
+\begin{frame}{Overlay-aware commands}
+
+Many ``inline'' commands (also to be found at \alert{Edit\lyxarrow Text Style})
+are overlay-aware.
+\begin{itemize}
+\item Thus, you can make for instance text on specific slides \emph<2>{emphasized},
+\textbf<3>{bold}, shown in \alert<4>{alert} or \structure<5>{structure}
+color.
+\end{itemize}
+\begin{block}<6>{Tip}
+
+Use these Emphasize and Bold insets (instead of the usual respective
+font settings) also if you do not need overlay specifications. Due
+to the way emphasized and bold is defined in \structure{Beamer},
+normal emphasizing and boldface can lead to \LaTeX{} errors, e.\,g.
+when used in section headings.
+\end{block}
+\end{frame}
+%
+
+\section{Specific environments}
+\begin{frame}{Specific environments}
+
+Specific environments, particularly suited for presentations are:
+\begin{itemize}
+\item Diverse ``blocks''
+\item Theorem-style environments
+\item Columns
+\end{itemize}
+We sketch them briefly in what follows.
+\end{frame}
+%
+\begin{frame}{Blocks}
+
+Blocks can contain all sorts of information. We used them here for
+``tips'' and ``hints''. The class provides 3 pre-defined blocks
+with different look:
+\begin{block}<2->{Block}
+
+A general-purpose block
+\end{block}
+\begin{exampleblock}<3->{Example Block}
+
+A block for ``examples''
+\end{exampleblock}
+\begin{alertblock}<4->{Alert Block}
+
+And an ``alert'' block for important remarks.
+\end{alertblock}
+\end{frame}
+%
+\begin{frame}{Handling Blocks}
+\begin{itemize}
+\item In \LyX , blocks have a similar user interface to frames, which means
+that
+\begin{itemize}
+\item Content inside blocks needs to be nested (if the paragraph layout
+is not \structure{Block})
+\item Consecutive blocks of the same type must be separated by the \structure{Separator}
+paragraph style
+\begin{block}<only at 2>{Tip}
+
+Use \alert{Edit\lyxarrow Start New Environment} (\shortcut{undefined})
+to quickly start a new block from within a previous block!
+\end{block}
+\end{itemize}
+\item Blocks are overlay-aware
+\end{itemize}
+\end{frame}
+%
+\begin{frame}{Theorem-style environments}
+
+\framesubtitle{(Theorem, Corollary, Definition, Definitions, Example, Examples,
+Fact, Proof)}
+
+Theorems look similar to blocks in the output, but they have a fixed
+title (depending on the type).
+\begin{theorem}
+This is a theorem!
+\end{theorem}
+
+\begin{fact}
+This is a fact!
+\end{fact}
+
+
+\pause{}
+
+Via \alert{Insert\lyxarrow Additional Theorem Text}, you can add
+some extra text to this fixed title
+\begin{example}[a bad one!]
+
+An example with additional text (brackets added automatically)
+\end{example}
+
+\end{frame}
+%
+\begin{frame}{Columns}
+
+Sometimes it is useful to divide a presentation into columns
+\begin{columns}[t]
+
+\column{.4\textwidth}
+
+To do this, first select \structure{Columns} (note the plural) to
+start the columns
+
+\pause{}
+
+\column{.4\textwidth}
+
+And then, in the following paragraph, select \structure{Column} (singular)
+to start a specific column
+\end{columns}
+
+
+\pause{}
+
+\medskip{}
+
+Note:
+\begin{itemize}
+\item In the \structure{Column} (singular) environment, you need to specify
+the width using \LaTeX{} syntax (but also something like ``3.5cm''
+will work)
+\item Any (singular) \structure{Column} must be nested to the (plural)
+\structure{Columns}. Likewise, column content can be any paragraph
+style that is nested to a singular \structure{Column}
+\end{itemize}
+\end{frame}
+%
+
+\section{Short remarks on modes}
+\begin{frame}{Modes}
+
+In \structure{Beamer} terms, a ``mode'' is a specific output route.
+There are several modes for different purposes. We just want to highlight
+three:
+\begin{enumerate}
+\item The ``beamer'' mode
+\item The ``presentation'' mode
+\item The ``article'' mode
+\end{enumerate}
+The beamer mode is the default. Unless explicitly specified otherwise,
+your \structure{Beamer} document is in ``beamer'' mode.
+\end{frame}
+%
+\begin{frame}<presentation>{Switching Modes}
+
+However, you can switch document parts, frames, headings and all ``action''-aware
+environments to a different mode. For instance, we have switched this
+frame to ``presentation'' mode.
+\begin{itemize}
+\item What does this mean?
+\begin{itemize}
+\item It means that this frame will only be visible in the presentation,
+not in the accompanying ``article'', if you produce such an article
+(we will elaborate on this a bit below)
+\end{itemize}
+\end{itemize}
+\end{frame}
+%
+\begin{frame}<article>{Switching Modes}
+
+This frame will not be visible in the presentation, but only in the
+article, since it is in ``article'' mode.
+\end{frame}
+%
+\begin{frame}{So what?}
+
+This is actually pretty useful! You can set up a single document and
+produce both a presentation and \textendash{} using the article mode
+\textendash{} a handout.
+\begin{itemize}
+\item And we mean a \emph{real}, useful handout, not one of those scaled
+slide printouts that are so common nowadays (but if you insist, you
+can produce one of those as well)
+\item Modes allow you to add extra text to the handout or hide parts from
+it
+\item You can use for instance different graphics for the presentation and
+the handout
+\item and so on \ldots{}
+\end{itemize}
+\end{frame}
+%
+\begin{frame}{Examples}
+
+As said, many elements are mode-aware.
+\begin{itemize}
+\item You can show particular text \only<presentation>{only in the presentation}\only<article>{only in the article}
+via \alert{Edit\lyxarrow Text Style\lyxarrow Only}
+\end{itemize}
+\mode<article>{\begin{itemize}
+\item Or put all sorts of complex contents via \alert{Insert\lyxarrow Custom Insets\lyxarrow ArticleMode}
+in an inset that will only be output in article mode
+\end{itemize}
+}\mode<presentation>{\begin{itemize}
+\item Or put all sorts of complex contents via \alert{Insert\lyxarrow Custom Insets\lyxarrow PresentationMode}
+in an inset that will only be output in presentation mode
+\end{itemize}
+}
+\begin{itemize}
+\item Or you can define that an \emph<presentation>{emphasizing} should
+only apply to the presentation, \textbf<article>{a bold face} only
+to article
+\item You can also show section headings or frame titles\slash subtitles
+only in the presentation\slash article (like we do for the ``Contents''
+and ``References'' frame titles in this presentation)
+\item And much more of this sort \ldots{}
+\end{itemize}
+\end{frame}
+%
+\begin{frame}{Setting up an article}
+
+Setting up a beamer article with \LyX{} is easy.
+\begin{itemize}
+\item Just create a new document with the class \structure{Beamer Article (Standard Class)}
+or \structure{Beamer Article (KOMA-Script)}
+\item Then add the presentation to this document as a child (via \alert{Insert\lyxarrow File\lyxarrow Child Document\ldots})
+\item And that's it. Now you can produce the handout and the presentation
+by compiling one of these two documents, while you only need to edit
+one, namely the presentation
+\end{itemize}
+Check out the accompanying beamer-article example document for this
+presentation. You can find it in the same folder as this document.

+\section{Changing the look}
+\begin{frame}{Themes}
+\begin{itemize}
+\item \structure{Beamer} presentations are themeable. Themes determine
+the colors used, the macro structure (use of sidebars, headlines etc.),
+the fonts, the look of list items, blocks and in general the whole
+look and feel of a presentation
+\item \structure{Beamer} itself ships a number of different-looking themes
+to chose from (we use the ``Berkeley'' theme in this presentation;
+see \alert{Document\lyxarrow Settings\lyxarrow\LaTeX{} Preamble}
+for how we activated and slightly tweaked the theme)
+\item In addition to this standard set, you can get more themes from \href{http://www.ctan.org}{CTAN}
+and other places at the Internet
+\item If you still are not satisified or if you need a theme matching to
+your University's or company's corporate design, the \structure{Beamer}
+manual \cite{beamer-ug} explains how you can setup your own theme
+\end{itemize}
+\end{frame}
+%
+\begin{frame}{Themes can be modified}
+
+But you do not need to write a theme from scratch if you want to alter
+the look.
+\begin{itemize}
+\item Existing themes can be modified both in details and in major areas
+(such as the coloring)
+\item Consult the \structure{Beamer} manual \cite{beamer-ug} for details
+\end{itemize}

+\section{And more \ldots}
+\begin{frame}{\ldots{} much more!}
+
+Note that \structure{Beamer} can do much more than we have described
+here. The \structure{Beamer} manual \cite{beamer-ug} provides a
+comprehensive documentation.
+
+Also, have a look at the \structure{Beamer} examples and templates
+shipped with \LyX !
