+\subsection{What is a \vym map?}
+A \vym map (in short words {\em map}) is a tree like structure:
+\begin{center}
+	\includegraphics[width=12cm]{example1.png}
+\end{center}
+Such maps can be drawn by hand on a paper or flip chart and help to
+structure your thoughts. While a tree like structure like above can be
+drawn manually \vym offers much more features to work with such maps.
+\vym is not another drawing software, but a tool to store and modify
+information in an intuitive way. For example you can reorder parts of
+the map by pressing a key or add various information like a complete
+email by a simple mouse click.
+
+Once you have finished collecting and organizing your ideas, you can
+easily generate for example a presentation in Open~Office based on a
+map.
+
+\subsection{Why should I use maps? Time, Space and your Brain.}
+\subsubsection*{Space}
+A map can concentrate a very complex content on little space e.g. a
+piece of paper. It helps to use both sides of your brain: the logical
+side and also your creative side (e.g. by using pictures, colors and
+keywords in a map, so called {\em anchors}).  It is a technique to
+organize the way you think: It can help you by developing, sorting and
+memorizing your thoughts. 
+
+\subsubsection*{Time}
+Because you just use keywords and drawings, it is much faster than good
+old fashioned notes. Your brain memorizes things by associating them to
+other things -- a map makes use of those connections and stimulates
+new asccociations. 
+
+
+\subsubsection*{Your Brain}
+In 1960 the Prof. {\sc Roger Sperry} discovered that both hemispheres
+of the human brain have different tasks (of course both of them
+basically {\em can} do the same): 
+\begin{center}
+\begin{tabular}{|p{5.5cm}|p{5.5cm}|} \hline
+	Left side & Right side \\ \hline
+	\begin{itemize}
+	   \item verbal speech and writing 
+	   \item numbers
+	   \item logical thinking
+	   \item analyzing and details
+	   \item science
+	   \item linear thinking
+	   \item concept of time
+	\end{itemize} &
+	\begin{itemize}
+		\item body language
+		\item visual thinking, day dreams
+		\item intuition and emotion
+		\item overview of things
+		\item creativity
+		\item art, music, dancing
+		\item non-linear thinking, connecting things
+		\item spatial awareness
+	\end{itemize}     \\ \hline
+\end{tabular}	
+\end{center}
+In our science oriented society we have learned to mainly rely on our
+left side of the brain, the "rational" one. In other cultures,
+especially like the native americans and other "old" cultures, the right
+side is much more important. Maps are just one way to stimulate the
+other side and make use of additional ressources we all have.
+
+
+\subsection{Where could I use a map?}
+Here are some examples, how you can use those maps
+\begin{itemize}
+    \item to prepare articles, papers, books, talks, \ldots
+    \item to sort complex data
+    \item to memorize facts, persons, vocabulary, \ldots
+    \item to sort emails, files and bookmarks on your computer
+    \item to moderate conferences
+\end{itemize}
+
+\subsection{What you shouldn't do with a map...}
+A map drawn by somebody shows the way the author thinks. There is
+no right or wrong in the way it is drawn, so there is no way to criticize
+it. "It is, what it is" ({\sc F.~Lehmann}).

+
+\subsection{Internet Ressources} 
+A good starting point to learn more about maps in general is Wikipedia:
+\begin{itemize}
+	\item English: 
+		\href{http://en.wikipedia.org/wiki/Mind_map}{http://en.wikipedia.org/wiki/Mind\_map}
+	\item German: 
+		\href{http://de.wikipedia.org/wiki/Mindmap}{http://de.wikipedia.org/wiki/Mindmap}
+\end{itemize}
+
+
+
+
+\section{Concept of \vym}
+%TODO may add a general introduction here...
+\subsection{Windows: mapeditor and noteeditor}
+\vym uses two windows: an editor for the map itself and another one for
+notes, which are part of the map. Let's call them {\em mapeditor} and
+{\em noteeditor}: 
+\begin{center}
+	\includegraphics[width=8cm]{windows.png}
+\end{center}
+Usually you will work in the {\em mapeditor} by just adding new
+branches, moving around and reordering them. The various ways to do this
+will be explained in \ref{mapeditor}. You can store additional
+information e.g. the content of a email easily in a {\em branch}: Just
+type or copy\&paste it into the {\em noteeditor}. Working with notes is
+explained in \ref{noteeditor}
+
+\subsection{Menus and Context menus}
+On top of each window you find the menubar. The options you find there
+are similar to those you are used from other applications. Note that
+many (and even more) options are availabe via {\em context menus}. Those
+are available if you right-click onto an object in a map (on Mac~OS~X
+Command-Click).
+
+\subsection{Toolbars}
+The toolbars in the mainwindows give quick access to many functions and
+also visualize the state of an object. For example a part of of the map
+can be hidden when the map is exported into an Open~Office presentation.
+To show this the branch in the map will have a little cloud symbol,
+which is also "switched on" in the toolbar.
+
+Note that you can reposition all toolbars by simply grabbing them. For
+example you can move the flags-toolbar from its original horizontal
+position on top of the mapeditor to a vertical position on the right
+side. You can even detach it and make it "float" separate from the other
+windows. Or just insert it again at its original position.
+
+\subsection{Maps}
+The map itself has always a {\em mapcenter}.  The
+mapcenter has {\em branches} just like the trunk of a tree. Each branch
+in turn may have branches again.
+\begin{center}
+	\includegraphics[width=10cm]{branches.png}
+\end{center}
+We will call a branch directly connected to the mapcenter a {\em
+mainbranch}, because it determines the position of all its child
+branches.
+
+The mapcenter and the branches all have a {\em heading}. This is the
+text you see in the mapeditor. Usually it should just be one or a few
+words, so that one can easily keep track of the whole map.
+
+
+In the toolbar above the mapeditor you see various symbols.
+\begin{center}
+	\includegraphics[width=8cm]{default-flags.png}
+\end{center}
+These are called {\em flags} and can be used to mark branches in the
+map, e.g. if something is important or questionable. 
+There are also more flags set by \vym automatically to show additional
+information, e.g. when a  exists for a  particular branch.
+
+By default some of these flags are set exclusively e.g. when the 
+"thumb-up" flag is set, then the "thumb down" is unset and vice
+versa. You can change this default behaviour in the settings menu.
+
+%TODO add info about toolbars e.g. undo/redo, ...
+
+\section{Mapeditor} \label {mapeditor}
+\subsection{Start a new map}
+After \vym is started two windows will open: the mapeditor and the
+noteditor. Usually you will work in both windows, but at the moment we
+will just need the mapeditor. 
+
+Select the mapcenter "New map" in the middle of the mapeditor by
+left-clicking with the mouse. It will turn yellow to show that is
+selected. There are several ways to add a new branch to the center:
+\begin{itemize}
+	\item Using the mouse: Open the context meny by clicking with the
+	right mouse button (CTRL-Click on Mac) onto the
+	mapcenter and choose Add \ra Add as child
+	\item Press \key{Ins} or \key{A}
+\end{itemize}
+A new branch will appear and you will be able to type the heading of the
+branch. Finish adding the new branch by pressing \key{Enter}.
+%tipp
+Sometimes it comes handy to add a new branch above or below the current
+one. Use \key{Ins} together with \key{Shift} or \key{Ctrl}. It is also
+possible to add a branch in such a way, that the current selection
+becomes the child of the new branch, which is like inserting it {\em
+before} the selection. This can be done using the context menu.
+
+\subsection{Navigate through a map}
+\subsubsection*{Select branches}
+To select branches you can use the left button of your mouse or also the
+arrow keys. Depending on the {\em orientation} of a branch type
+\key{\la} or \key{\ra} to get nearer to the mapcenter or deeper
+down into the branches. Within a set of branches, let's call them a 
+{\em subtree}, you can use \key{\ua} and \key{\da} to go up and down. You can
+also use \key{Pos1} and \key{End} to select the first and last branch.
+
+
+\subsubsection*{Zoom a map}
+While adding more and more branches the size of the map may become
+bigger than the mapeditor window. You can use the scrollbars on the
+right and the bottom of your mapeditor window to scroll, but it is
+easier to just scroll using the left mouse button: Click onto the {\em
+canvas} itself, the empty space somewhere between the branches. The
+mouse pointer will change from an arrow to a hand, now move the visible
+part of the map to show the desired part.
+
+If you select branches using the arrow keys, the map will scroll
+to ensure that the selected branch is always visible.
+
+Working with huge maps, the {\em zoom}-function comes in handy: You can
+use 
+\begin{itemize}
+	\item from the menu View \ra Zoom
+	\item the toolbar buttons 
+		\begin{center}
+			\includegraphics[width=3cm]{zoom-buttons.png}
+		\end{center}	
+\end{itemize}	
+The crossed magnifying lens resets the zoomed view to its original size.
+
+
+\subsubsection*{Find Function} \label{findwindow}
+With huge maps there is the need to have a
+find function. Choose Edit \ra Find to open the Find Window:
+\begin{center}
+	\includegraphics[width=6cm]{find-window.png}
+\end{center}	
+The text you enter here will be searched in all the headings and also in
+notes. Everytime you press the "Find"-button it will look for the next
+occurence, which then will be selected automatically. If the search
+fails, there will appear a short message "Nothing found" or a few
+seconds in the {\em statusbar} on the bottom of the mapeditor.
+
+\subsubsection*{Keep the overview -- scroll a part of the map}
+A very big subtree of a map e.g. a branch with hundreds of childs makes
+it very hard to keep an overview over the whole map. You can hide all
+the childs of a branch by {\em scrolling} it -- this function is also
+often called {\em folding}. Think of the whole subtree as painted onto a
+big newspaper. You can scroll the paper to a small roll, leaving just
+the headline readable.
+
+To scroll or unscroll a branch and its childs, press the
+\begin{itemize}
+	\item \key{Scroll} key or  \key{S}
+	\item press the middle-mouse button or
+	\item choose the little scroll from the toolbar.
+\end{itemize}
+If you select parts of a scrolled branch e.g. using the find function or
+by using the arrow-keys, it will unscroll temporary. This is shown as a
+scroll with a little hour glass. If the temporary unscrolled part is not
+longer needed, it will be hidden again automatically. It is also
+possible to unscroll all branches using "Edit\ra Unscroll all scrolled
+branches".
+
+You can also hide parts of the map while exporting it e.g. to a webpage
+or a presentation, see \ref{hideexport} for details.
+
+\subsection{Modify and move branches}
+\subsubsection*{Modify the heading}
+You can edit the heading by selecting the branch and then
+\begin{itemize}
+	\item pressing \key{Enter}
+	\item double-clicking with left mouse.
+\end{itemize}
+Just type the new heading (or edit the old one) and press \key{Enter}.
+
+\subsubsection*{Move a branch}
+The easiest way to move a branch is to select it with left-mouse and
+drag it to the destination while keeping the mouse button pressed.
+Depending on the branch  it will be
+\begin{itemize}
+	\item moved to the destination or
+	\item {\em linked} to a new {\em parent} (mapcenter or branch)
+\end{itemize}
+If you drag the branch over another one or over the mapcenter, you will
+notice that the  link connecting it to the old parent will be changed to
+lead to the  new parent which is now under your mousepointer. 
+If you release the button now, the branch will be relinked.
+
+If you release the button in the middle of nowhere, the result will
+depend on the type of branch you are releasing:
+\begin{itemize}
+	\item A mainbranch is directly connected to the mapcenter.
+		It will stay on its new position.
+	\item An ordinary branch will "jump" back to its original position.	
+\end{itemize}
+Thus you can easily rearrange the layout of the mainbranches to avoid
+overlapping of their subtrees.
+There is another convenient way to move branches, especially if you want
+to {\em reorder} a subtree: You can move a branch up or down in a
+subtree by
+\begin{itemize}
+	\item pressing \key{\ua} and \key {\da}
+	\item selecting Edit \ra Move branch
+	\item clicking on the toolbar buttons:
+		\begin{center}
+			\includegraphics[width=1.5cm]{move-buttons.png}
+		\end{center}	
+\end{itemize}
+%tipp
+There is yet another way to move branches: If you press \key{Shift} or
+\key{Ctrl} while moving with the mouse, the branch will be added above
+or below the one the mouse pointer is over. This helps also to reorder a
+map.
+
+\subsection{The right side of your brain - colors and images}
+\subsubsection*{Change color of a heading}
+You can also use colors to put more information into a map, e.g. use
+red, green and more colors to prioritize tasks. Again you can
+\begin{itemize}
+	\item use the menu and choose e.g Format \rq Set Color
+	\item use the toolbar
+		\begin{center}
+			\includegraphics[width=3cm]{color-buttons.png}
+		\end{center}	
+\end{itemize}
+The first button (black in the graphic above) shows the actual color.
+Clicking on it let's you choose another color. You can also "pick"
+another color by selecting a branch with the desired color and using the
+"pick color" button. Both of the buttons showing a bucket actually put
+the current color to the selected branch. While the first one just
+colors the heading of the selection, the last one also colors all the
+childs of the selected branch.
+
+%tipp
+A very useful function is the "copy color" using the mouse: Select the
+branch which should get the new color, then press \key{Ctrl} and
+simultanously click with left-mouse on another branch to copy its color
+to the first one. Here the childs of the selection also will get the new
+color, if you just want to color the selection itself, additionally
+press \key{Shift}.
+
+\subsubsection*{Use flags}
+\vym provides various flags. You see them in the toolbar on top of the
+mapeditor window. (Note: Like all toolbars you can also move them to the
+left or the right side of the window or even detach them. Just grab the
+very left "dotted" part of the toolbar with your left-mouse button.) 
+\begin{center}
+	\includegraphics[width=8cm]{default-flags.png}
+\end{center}
+If you have a branch selected, you can set any number of flags by
+clicking them in the toolbar. The toolbar buttons change their state and
+always reflect the flags set in the selected branch.
+
+Presently \vym uses two kinds of flags: {\em System Flags} and {\em
+Standard Flags}. The standard flags are those shown in the toolbar.
+System flags are set by \vym to indicate e.g. that there is additional
+information in a note (more on this in \ref{noteeditor}). Later versions
+of \vym may have another kind of flags, which may be edited by the user.
+
+\subsubsection*{Images}
+The easiest way to add an image to a branch is by dragging it e.g. from a
+webbrowser to the mapeditor while a branch is selected there.
+
+You can also add a image to a branch by opening the context menu of the
+branch choose "Add Image". A
+dialog window lets you choose the image to load. 
+\footnote{Supported image types are: PNG, BMP, XBM, XPM and PNM. It may
+	also support JPEG, MNG and GIF, if specially configured during
+	compilation (as done when \vym is part of SUSE LINUX).}
+While an image is selected in the dialog, you can see a preview of the
+image. It is also possible to select multiple images.	
+
+You can position the image anywhere you want, just drag it with left
+mouse. To relink it to another branch, press \key{Shift} while moving
+it. To delete it, press \key{Del}. 
+
+If you right-click onto an image, a context menu will open which let's
+you first choose one of several image formats. Then a file dialog opens
+to save the image. Hint: This is used to "export" the image, it will be
+saved anyway in the map itself! You can also cut and
+copy images, but it is not possible to add objects to an image\footnote{
+	Images are regarded as "extra feature". It would make working with
+	the map much more complex if e.g. images could be linked to images.}
+
+The option \lq{\bf Use for export} \rq controls the output of exports
+e.g. to HTML: If set to no, the image won't appear in the {\em text}
+part of the output. This is useful for large images or if images are
+used as a kind of frame e.g. the famous cloud symbol around a part of
+the map. Those shouldn't appear in the middle of the text.
+
+At the moment image support is preliminary: Images will be saved
+together with all the other data of a map in the {\tt .vym}-file.
+Later versions will include more functionality like resizing the images,
+changing its z-value (put it into background) etc.
+
+\subsubsection*{Frames}
+A frame can be added to a branch by clicking with the
+right-mouse button.  A context menu will open, where you can choose the
+frame. At the moment just a rectangle resp. "No Frame" will be offered,
+nevertheless you can use images as frames. Have a look at the demo map
+{\tt todo.vym} as an example, where the mapcenter is a cloud. You can
+use an external drawing program like {\tt gimp} to create an image,
+preferable with an transparency channel, so that you can design frames
+which don't use a rectangular borderline, just like the cloud.
+
+
+\subsection{Background design}
+The design of the background of a map and also of the links connecting
+various parts of the map can be changed by
+\begin{itemize}
+	\item Selecting Format from the menu
+	\item Right clicking onto the canvas, which will open a context menu
+\end{itemize}
+
+\subsubsection*{Background color}
+The color is set (and also displayed) as "Set background color".
+
+\subsubsection*{Link color}
+Links connecting branches can be colored in one of the following ways:
+\begin{itemize}
+	\item use the color of the heading of the branch the links is
+	\item use {\em one} color for all links. The default color is blue.
+	leading to.
+\end{itemize}
+The latter can be set with "Set link color". Check or uncheck the "Use
+color of heading for link" option to choose one of the two designs for
+your map.
+
+\subsubsection*{Link style}
+\vym offers four different styles for the appearences of links:
+\begin{itemize}
+	\item Line
+	\item Parabel
+	\item Thick Line
+	\item Thick Parabel
+\end{itemize}
+The "thick" styles only draw links starting at mapcenter thick, the rest
+of the map is always painted "thin".
+
+
+\subsection{Links to other documents and webpages}
+\vym supports two kind of external links:
+\begin{itemize}
+	\item Document, which will be opened in an external webbrowser
+	\item \vym map, which will be opened in \vym itself
+\end{itemize}
+In addition to the external links there also internal ones, leading from one
+branch in a map toanother one. Those are called {\em XLinks} and are explained
+in section~\ref{xlinks}.
+
+\subsubsection*{Webbrowser}
+Modern Webbrowsers like {\tt konqueror} are able to display various
+types of files, both local or in the internet. To enter the URL of
+any document, right-click  onto a branch or use the Edit Menu
+and choose "Edit URL". Enter the path to your document (or copy and
+paste it from your browser). Examples for valid paths are:
+\begin{verbatim}
+	http://www.insilmaril.de/vym/index.html
+	file:/usr/share/doc/packages/vym/doc/vym.pdf
+\end{verbatim}
+If an URL was entered, a little globe will appear in the branch. By
+clicking on the globe in the toolbar or the context menu an external
+browser\footnote{
+	The browser can be changed in the Settings Menu.}
+will be started.
+\begin{center}
+	\includegraphics[width=0.5cm]{flag-url.png}
+\end{center}
+For more information on working with bookmarks and webbrowsers see
+section \ref{bookmarks}.
+
+
+\subsubsection*{\vym map}
+To link to to another map right click on a branch or choose "Edit \ra
+Enter \vym link". A file dialog opens where you can choose the map. A
+branch with a link is marked with 
+\begin{center}
+	\includegraphics[width=0.5cm]{flag-vymlink.png}
+\end{center}
+Clicking this flag in the toolbar or in the context menu of a branch
+will open the map in another tab (see \ref{tabs} for working with
+multiple maps). To delete an existing link, just press the "Cancel"
+button.
+
+Technical note: Internally \vym uses absolute paths, to avoid opening
+several tabs containing the same map. When a map is saved, this path is
+converted to a relative one (e.g. {\tt /home/user/vym.map} might become
+{\tt ./vym.map}. This makes it fairly easy to use multiple maps on
+different computers or export them to HTML in future.
+
+\subsection{Multiple maps} \label{tabs}
+You can work on multiple maps at the same time. Each new map is opened
+in another {\em tab}. The available tabs are shown just above the
+mapeditor. You can use the normal cut/copy/paste functions to
+copy data from one map to another.

+\section{Noteeditor} \label {noteeditor}
+If you want to save more text in a branch e.g. a complete email, a
+cooking recipe, or the whole source code of a software project, you can
+use the noteeditor. 
+\begin{center}
+	\includegraphics[width=8cm]{noteeditor.png}
+\end{center}
+This editor displays text associated to a branch selected in the
+mapeditor. To visualize that there maybe is no text yet, the noteeditor
+shows different background colors depending on its state:
+
+\subsection{States}
+Before you can type or paste text into it, you have
+to select a branch in the mapeditor. Note that the background color
+of the noteeditor indicates its state:
+\begin{itemize}
+	\item black: no branch selected
+	\item grey: no text entered yet
+	\item white: text is already available
+\end{itemize}	
+To show you in the mapeditor itself that there is a note with more
+information for a particular branch, a little note flag will appear next
+to the heading of the branch. See the lower branch on the right side:
+\begin{center}
+	\includegraphics[width=8cm]{branches-flags.png}
+\end{center}
+
+\subsection{Import and export notes}
+The note is always saved automatically within the \vym file itself.
+Nevertheless sometimes it is nice to import a note from an external file
+or write it. Use "File\ra~Import" and "File\ra~Export" to do so. 
+
+\subsection{Edit and print note}
+Editing works like in any simple texteditor, including undo and redo
+functions. You can delete the complete note by clicking the
+trashcan. Only the note itself is printed by clicking the printer icon.
+
+When pasting into the editor using the X11 copy\&paste mechanism, the
+editor will create a paragraph for each new line. Usually this is not
+wanted, so there you can convert all paragraphs into linebreaks by using
+Edit~\ra~Remove~Paragraphs or \key{ALT-X}.
+
+\subsection{RichText: Colors, paragraphs and formatted text}
+\vym supports formatted text (QT Rich Text) in the noteeditor since
+version 1.4.7.  Colors and text attributes (e.g. italic, bold) can be
+set with the buttons above the text.  The text itself is divided in
+paragraphs. For each paragraph the format can be set (e.g. centered,
+right). A paragraph is ended when a \key{Return} is entered. If you just
+want to begin a new line, press \key{CTRL-Return}.
+
+\subsection{Fonts and how to quickly switch them}
+The noteeditor is ment to be used for simple notes, not really as full
+featured text editor. Because of many requests \vym supports now
+formatted text in the noteeditor\footnote{
+	\vym uses the QRichtText format, which is basically a subset of the
+	formatting provided in HTML.}
+Two default fonts are supported which can be set in the Settings menu.
+One is a fixed width font, the other has variable width. The fixed font
+is usually used for emails, source code etc.\ while the variable font is
+used for simple notes, where one doesn't need fixed character widths.
+Both fonts can easily switched using the following symbol from the
+toolbar:
+\begin{center}
+	\includegraphics[width=0.5cm]{formatfixedfont.png}
+\end{center}
+In the Settings menu both fonts can be set and also which font should be
+used for default. 
+
+Additionally to the default fonts any font installed on your system can
+be used. Please note, that the chosen font also will be used for HTML
+exports, so you should only use fonts which are available generally.
+
+\subsection{Find text}
+The noteeditor itself has no Find function, use Find in the mapeditor,
+which will also search all notes (see \ref{findwindow}).
+
+\subsection{Paste text into note editor}
+Often you will paste text into the editor from another application e.g.
+an email. Normally \vym will generate a new paragraph for each new line.
+This usually is not what you want, so you can choose from the menu
+

+This turns subsubsections in selected text (or all text, if nothing is
+selected) into linebreaks. This is especially useful for snippets of
+source code.
+
+\subsubsection*{Edit \ra Join Lines:}
+Tries to format text, so that empty lines are used to delimit
+paragraphs. This is done for selected text (or all text, if nothing is
+selected). Especially useful for text like emails, meeting minutes etc.
+
+\section{Hello world}
+This section is about how \vym can interact with other applications.
+Many applications meanwhile can read and write their data using XML, the
+eXtensible Markup Language. \vym also uses XML to save its maps, see
+\ref{fileformat} for a more detailed description. 
+
+So if your an application understands XML, chances are good that someone
+could write import/export filters for \vym. Volunteers are always
+welcome ;-)
+
+\subsection{Import} \label{import}
+
+\subsubsection*{KDE Bookmarks}
+The integrated bookmark editor in KDE is somewhat limited, so why not
+use \vym to maintain the bookmark mess? To create a new map containing
+your current KDE bookmarks just choose
+\begin{itemize}
+	\item File \ra Import\ra KDE Bookmarks
+\end{itemize}
+
+\subsubsection*{Mind Manager}
+\vym has currently a very basic import filter to convert maps created by
+{\em Mind Manager}\footnote{Mind Manager is a professional software by
+Mindjet. Both names are registered trademarks by Mindjet. For more
+information see their website at
+\href{http://mindjet.de}{http://mindjet.de}} into \vym maps. Notes and
+pictures are not converted at the moment. You can import files with
+\begin{itemize}
+	\item File \ra Import\ra Mind Manager
+\end{itemize}
+
+
+\subsubsection*{Directory structure}
+\vym can read a directory structure. This is mainly for
+testing \vym e.g. to easily create huge maps used for benchmarks (yes,
+there is still room to optimize \vym ;-)
+
+
+
+
+\subsection{Export}  \label{export}
+\label{hideexport}
+Often you don't want to export the whole map, but just parts of it. For
+example you may have additional info you want to talk about in a
+presentation, while those parts should not be visible to the audience.
+To achieve this you can "hide" parts of the map during exports by
+setting the "hide in export" flag.
+\begin{center}
+	\includegraphics[width=0.5cm]{flag-hideexport.png}
+\end{center}
+You can toggle this flag in the toolbar or by pressing \key{H}.
+Note that there is a global option in the settings menu to toggle the
+use of this flag. By default the flag is enabled.
+
+\subsubsection*{Open Office}
+Open Office beginning with version~2 uses the so called "Open Office
+Document Format", which can be written by \vym. The options are
+currently limited, but it possible to export presentations which can be
+opened in Open Office Impress. By selecting
+\begin{itemize}
+	\item File \ra Export\ra Open Office
+\end{itemize}
+you get a file dialogue where you can choose the output file and the
+file type:
+\begin{center}
+	\includegraphics[width=12cm]{export-oo.png}
+\end{center}
+The file types represent various templates, which can be created with
+some manual work from an existing Open Office document. The structure of
+\vym map is then inserted into a template. 
+There are some limitations at the moment:
+\begin{itemize}
+	\item \vym can't take care of page lengths, so you have to check and
+	probably reedit in Open Office to avoid text running over the end of
+	a page
+	\item Images and flags are not used at the moment
+	\item Notes are just written as plain text, without RichText
+\end{itemize}
+Some of the templates make use of {\em sections} e.g. insert the
+headings of mainbranches as chapters for sections into the presentation.
+
+\subsubsection*{Image}
+\vym supports all image formats which are natively supported by the
+QT~toolkit:
+BMP, JPEG, PBM, PGM, PNG, PPN, XPM, and XBM.
+For use in websites and for sending images by email PNG is a good
+recommodation regarding quality and size of the image. \vym uses QTs
+default options for compressing the images.
+
+\subsubsection*{ASCII}
+Exporting an image as text is somewhat experimental at the moment. Later
+this will probably done using stylesheets. So the output may change in
+future versions of \vym.
+
+\subsubsection*{\LaTeX}
+\vym can generate an input file for \LaTeX. Currently this is considered
+as experimental, there are no options (yet). 
+By selecting
+\begin{itemize}
+	\item File \ra Export\ra \LaTeX 
+\end{itemize}
+you will be asked in a file dialog for the name of the output file. This
+file should be included in a \LaTeX document using command  
+\begin{verbatim}
+	\include{inputfile.tex}
+\end{verbatim}
+
+\subsubsection*{KDE Bookmarks}
+\vym will overwrite the KDE bookmarks file and then try to notify
+running konquerors via DCOP of the changed file. \vym does not create a
+backup!
+\begin{itemize}
+	\item File \ra Export \ra KDE Bookmarks
+\end{itemize}
+
+
+\subsubsection*{XHTML (Webpages)}
+
+This is the format you want to use to create a webpage. For an example
+have a look at the \vym homepage: 
+\href{http://www.InSilmaril.de/vym}{www.InSilmaril.de/vym}
+
+Some explanation how this works: 
+Before a map is exported as XHTML, it will be first written as XML into a
+directory (see \ref{xmlexport}). Then the external program {\tt
+xsltproc}\footnote{On SUSE Linux {\tt xsltproc} is installed by
+default.}
+will be called to process the XML file and generate HTML code.
+A dialog allows to set various options:
+\begin{itemize}
+	\item {\bf Include image:} If set, \vym will creat an image map at
+	the top of the HTML output. Clicking on a branch in the map will
+	jump to the corresponding section in the output.
+
+	\item {\bf Colored headings:}
+	If set to yes, \vym will color the headings in the text part  with the
+	same colors like in the map.
+	\item {\bf Show Warnings:}
+	If set to yes, \vym will ask before overwriting data.
+	\item {\bf Show output:}
+	This is useful mainly for debugging. It will show how the processing of
+	the XML file works by calling the external {\tt xsltproc}.
+\end{itemize}
+Additionally the paths to the CSS and XSL stylesheets can be set. By
+default on SUSE~Linux they will be in {\tt /usr/share/vym/styles}.
+
+
+\subsubsection*{XML} \label{xmlexport}
+The map is written into a directory both as an image and as XML. The
+directory is set in a file dialog. If the directory is not empty, you
+will be questioned if you risk to overwrite its contents.
+
+It is possible to export different maps into the same directory. Each
+file generated will have the map's name as prefix, e.g. {\tt todo.vym}
+becomes {\tt todo.xml}, {\tt todo.png}, {\tt todo-image-1.png} and so
+on. This is useful if e.g. for a website several combined maps have to
+be stored in the same directory.
+
+\subsubsection*{Export a part of a map}
+Select a branch you want to export together with its childs, then open
+the context menu and choose {\em Save Selection}. This will create a
+file with the postfix {\tt .vyp}, which is an abbreviation for \lq vym
+part\rq.
+
+
+\section{Advanced Editing}
+
+\subsection{How to deal with Bookmarks} \label{bookmarks}
+\subsubsection*{Open new tabs instead of new windows}
+If you use konqueror as browser, \vym will remember the konqueror which
+was opened first by \vym. You can also press \key{Ctrl} and click to
+open the link in a new tab then.
+
+\vym can also open a new tab in Mozilla or Firefox using the remote
+command\footnote{\href{http://www.mozilla.org/unix/remote.html}{http://www.mozilla.org/unix/remote.html}}
+of these.
+
+\subsubsection*{Drag and Drop}
+If you want to keep bookmarks in a map, select a branch where you want
+to add the bookmark, then simply drag the URL from your browser to the
+map. Also you could use an existing heading as URL: Right click onto the
+branch and select "Use heading for URL".
+
+
+\subsubsection*{Directly access bookmark lists of a browser}
+Please see the sections \ref{import} and \ref{export} about
+Import and Export filters.
+
+\subsubsection*{Special URLs}
+\vym can turn an existing heading of a branch into an URL. Currently
+this works for Bugentries in the Novell Bugtracking system: Open the
+context menu of a branch (usually by right-clicking it) and select
+\begin{itemize}
+	\item Create URL to Bugzilla
+\end{itemize}
+The URL will be build from the number in the heading.
+
+\subsection{Including images into a branch} 
+The default setting of an image is to float "freely". They can be
+positioned everywhere, but they might end up in the same place as other
+parts of the map.
+
+The solution is to include them "into" a branch. This can be done via
+the context menu of their parent branch:
+\begin{itemize}
+	\item Include images horizontally
+	\item Include images vertically
+\end{itemize}
+The image ist still positioned relatively to its parent branch, but the
+heading and border of the branch adapt to the floating image, see below: 
+\begin{center}
+	\includegraphics[width=11cm]{includeImages.png}
+\end{center}
+
+\subsection{Modifier Modes} 
+Modifiers are for example the \key{Shift}- or the \key{Alt}-keys. When
+pressed while doing actions with the mouse, they will cause \vym to use
+a "modified" action. E.g. you can move branches with mouse. If
+\key{Ctrl} or \key{Alt}is pressed while releasing the branch, it will be
+added above/below the target, not as child of the target.
+
+Without a modifier pressed, the first click on a branch just selects
+it. For the behaviour of the \key{Ctrl} modifier there are several
+options, which can be set from the modifier toolbar:
+\begin{center}
+	\includegraphics[width=3cm]{modmodes.png}
+\end{center}
+The default  is to copy the color from the clicked branch to the already
+selected branch. In the toolbar shown above the default modifier is
+selected, namely to copy the color of a branch. The second modifier
+let's you easily copy a whole branch with a single click. The third
+modifier lets you create {\em xLinks}, which will be explained in the
+next section.
+
+\subsection{Hide links of unselected objects}
+Sometimes it would be useful to position a branch freely, just like a
+mainbranch or an image. Though this is not possible (yet) for all
+branches, you can use a mainbranch and hide its connecting link to the
+mapcenter. This can be used e.g. for legends or a collection of vymLinks
+pointing to other maps:
+\begin{center}
+	\includegraphics[width=9cm]{hiddenlink.png}
+\end{center}
+
+
+\subsection{XLinks} \label{xlinks}
+So far all the data in the \vym map has been treelike. Using xLinks you
+can link one branch to any other, just like attaching a rope between two
+branches in a real tree. This is especially useful in complex maps,
+where you want to have crossreferences which don't fit on the same
+visible area, which fits on your screen. The following example, which is
+part of the \vym package, still fits on one screen, but shows how data
+can be crosslinked. In the graphics there is a link from a task (prepare
+a presentation) to general information:
+\begin{center}
+	\includegraphics[width=12cm]{xlink.png}
+\end{center}
+Note that a xLink which points to a branch that is not visible (because
+it is scrolled), is just show as a little horizontal arrow. In the
+screenshot above have a look at the \lq Tuesday\rq\ branch.
+
+\subsubsection*{Create a xLink}
+Choose the link mode from the modifier toolbar (by clicking or pressing
+\key{L}). Select the branch, where the xLink should start. Press the
+modifier key \key{Ctrl} and simultanously click on the branch where the
+link should end. (The link is already drawn before you release the mouse
+key). If you release the mouse over a branch the xLink becomes
+permanent.
+
+\subsubsection*{Modify or delete a xLink}
+Open the context menu of a branch and select \lq Edit xLink\rq. A
+submenu contains all the xLinks of the branch (if there are any). They
+are named like the branches, where they end. Choose one and
+the xLink dialogue opens, where you can set color, width and also delete
+the xLink.
+
+\subsubsection*{Follow a xLink}
+In a complext \vym map it sometimes comes handy to jump to the other end
+of a xLink. You can do this by opening the context menu of the branch
+and clicking on \lq Goto xLink\rq and selecting the xLink you want to
+follow.
+
+
+
+\subsection{Adding and removing branches}
+The context menu of a branch shows some more ways to add and delete data
+e.g. you can delete a branch while keeping its childs. The childs become
+linked to the parent of the previously removed branch.
+Similar branches can be inserted into existing maps. For keyboard
+shortcuts also have a look at the context menu.
+
+\subsection{Adding a whole map or a part of a map}
+Select a branch where you want to add a previously saved map ({\tt .vym})or a part
+of a map ({\tt .vyp}) , then open
+the context menu and choose {\em Add \ra Import}. For the import you can
+choose between {\em Import Add} and {\em Import Replace}: The imported
+data will be added after the selection resp. replace the selection.
+
+
+\section{\vym on Mac OS X}
+\subsection{Overview}
+Basically there are two ways to run \vym on Macs:
+\subsubsection*{QT Mac Edition:}
+	\vym here provides the well known Mac look and feel.  \vym is
+	available as zipped Mac OS X application. It has been compiled and
+	tested in Mac~OS~10.3, but should also work on Tiger. It is using
+	the Mac version of Trolltechs QT library.  
+\subsubsection*{X11}
+	\vym can also be run using the Linux version, but then menus and
+	handling will also be those of the Linux version e.g. The menu bar
+	will look different. 
+
+\subsection	{Contextmenu and special keys}
+Most Macs unfortunatly just have a single mouse button. In order to show
+the context menu which usually would be opened with the right mouse
+button, you can click while pressing the \key{kommand}-key.
+
+Especially on Laptops some of the keys usually used on PC keyboards seem
+to be missing. The QT-Mac Edition of \vym has its own keyboard
+shortcuts. To find the shortcuts just have a look at all the menu
+entries, the shortcut is visible next to an entry. Toolbar buttons also
+may have shortcuts, just position the mouse pointer over a button and
+wait for the little help window to appear. 
+
+\subsection {Viewing external links}
+\vym on Mac uses the system call {\tt /usr/bin/open} to view links.
+Mac~OS determines automatically if the link is a pdf or www page and
+opens the right browser.
+
+
+\begin{appendix}
+
+\section{Starting \vym}
+\subsection{Path to ressources}
+\vym will try to find its ressources (images, stylesheets, filters,
+etc.) in the following places:
+\begin{enumerate}
+	\item Path given by the environment variable {\tt VYMHOME}.
+	\item If called with the local option (see \ref{options} below),
+	      \vym will look for its data in the current directory.
+	\item {\tt /usr/share/vym}
+	\item {\tt /usr/local/share/vym}
+\end{enumerate}
+
+\subsection{Command line options} \label{options}
+\vym has the following options:
+\begin{center}
+\begin{tabular}{ccp{8cm}}\\ 
+\bf Option	& \bf Comment & \bf Description \\ \hline
+v & version & Show version ov \vym\\
+l & local	& Use local paths to stylesheets, translations, icons, 
+              etc. instead of system paths. Useful for testing\\
+h & help	& Show help\\
+q & quit	& Quit immediatly after startup. Useful for benchmarks.\\
+\end{tabular}
+\end{center}
+You can also give several filenames at the commandline to let \vym open
+several maps at once.
+ 
+\section{Contributing to \vym}
+So far I'd say I have written 98\% of the code on my own. No surprise,
+that \vym exactly fits my own needs. Nevertheless I would like to
+encourage all users of  \vym to contribute. Maybe not only with feature
+requests, but also with code, new import/export filters, translations
+etc. In this appendix I'll try to show how easy it is to expand the
+things you can do already with \vym. I really look forward to hear from
+you!
+
+\subsection{Getting help}
+
+\subsubsection*{Frequently asked questions}
+Please refer to the FAQ available on the \vym website:
+\begin{center}
+\href{http://www.InSilmaril.de/vym/faq.html}{http://www.InSilmaril.de/vym/faq.html}
+\end{center}
+
+\subsubsection*{Mailinglists}
+There are two mailinglists: {\tt vym-forum} is the \vym users forum to
+discuss various questions, while {\tt vym-devel} is intended for people
+interested in contributing to \vym. You can view the archives and
+subscribe at
+\begin{center}
+\href{https://sourceforge.net/mail/?group_id=127802}{https://sourceforge.net/mail/?group\_id=127802}
+\end{center}
+
+\subsubsection*{Contacting the author}\label{author}
+Especially for support questions please try the mailinglists first. If
+everything else fails you can contact the Uwe Drechsel at
+\begin{center}
+\href{mailto:vym@InSilmaril.de}{vym@InSilmaril.de}
+\end{center}
+
+
+
+\subsection{How to report bugs}
+Though Sourceforge has its own bugreporting system, I'd rather prefer if
+you contact me directly (see \ref{author}) or even better: You can file
+a bugreport in Bugzilla, the bugtracking system of openSUSE:
+\begin{center}
+\href{http://en.opensuse.org/Submit_a_bug}{http://en.opensuse.org/Submit\_a\_bug}
+\end{center}
+I build \vym regulary for openSUSE, so you may report it against a
+recent version there, even if you  use another Operating System.
+Please don't forget to tell 
+\begin{itemize}
+	\item the exact steps needed to reproduce the bug
+	\item the version and build date of \vym (see the Help \ra About
+	\vym)
+	\item hardware and Operating System
+\end{itemize}
+
+\subsection{Compiling from the sources}
+\subsubsection{Getting the sources} \label{getsources}
+You find the latest version of \vym at the project site:
+\begin{center}
+\href{https://sourceforge.net/projects/vym/}{https://sourceforge.net/projects/vym/}
+\end{center}
+There you can check them out of the source repository (CVS):\\
+
+\begin{verbatim}
+cvs -d:pserver:anonymous@cvs.sf.net:/cvsroot/vym checkout code
+\end{verbatim}
+
+\subsubsection{The Qt toolkit}
+Qt is C++ toolkit for multiplatform GUI and application development. It
+provides single-source portability across MS~Windows, Mac~OS~X, Linux
+ans all major commercial Unix variants. Qt is also available for
+embedded devices. Qt is a Trolltech product. For more information see 
+\begin{center}
+\href{http://www.trolltech.com/qt/}{www.trolltech.com/qt} 
+\end{center}
+
+
+\subsubsection{Compiling \vym }
+Make sure you have installed your Qt environment properly, see the Qt
+documentation for details. You need to have the Qt command {\tt qmake}
+in your {\tt PATH}-environment, then run
+\begin{verbatim}
+qmake
+make  
+make install
+\end{verbatim}
+The last command {\tt make install} needs root-permissions. Of course it
+may be omitted, if you just want to test \vym.
+
+%\subsubsection*{Compiling \vym on Macs}
+%TODO
+
+\subsection{\vym file format} \label{fileformat}
+\vym maps usually have the postfix "{\tt .vym}" and represent a
+compressed archive of data. If you want to have a
+closer look into the data structure map called "mapname.vym", 
+just uncompress the map manually using
+\begin{verbatim}
+	unzip mapname.vym
+\end{verbatim}
+This will create directories named {\tt images} and {\tt flags} in your
+current directory and also the map itself, usually named {\tt
+mapname.xml}.
+The XML structure of \vym is pretty self explaining, just have a look at
+{\tt mapname.xml}.
+
+This XML file can be loaded directly into \vym, it does not have to be
+compressed. If you want to compress all the data yourself, use
+\begin{verbatim}
+	zip -r mapname.vym .
+\end{verbatim}
+to compress all data in your current directory.
+
+\subsection{New features}
+There are lots of features which might find their way into \vym.
+Together with \vym you should have received a directory with several
+maps e.g. on SUSE~LINUX this is
+\begin{center}
+	{\tt /usr/share/doc/packages/vym/demos}
+\end{center}
+where you find the map {\tt todo.vym}. It lists quite a lot of things to
+be done in future. If you have more ideas, contact the development team
+at
+{\tt vym-devel@lists.sourceforge.net}.
+
+
+\subsection{New languages support}
+In order to add a new language to \vym you need 
+the sources (see \ref{getsources}) and
+an installation of Trolltechs QT. A part of QT are the development
+tools, from those tools especially the translation tool "Linguist" is
+needed. 
+
+In some Linux distributions the development tools are in an extra package, e.g. on SUSE LINUX you should have installed:
+\begin{verbatim}
+    qt3-devel.rpm
+    qt3-devel-doc.rpm
+    qt3-devel-tools.rpm
+    qt3-man.rpm
+\end{verbatim}
+If you don't have QT in your system, you can get it from 
+	\href{http://www.trolltech.com}{http://www.trolltech.com} Once you
+	are able to compile vym yourself, you can translate the text in vym
+	itself by performing the following steps:
+\begin{itemize}
+	\item Let's assume now your encoding is "NEW" instead of for example
+	"de" for german or "en" for english
+	
+	\item Copy the file {\tt lang/vym\_en.ts} to l{\tt ang/vym\_NEW.ts} (The code
+	itself contains the english version.)
+		
+	\item Add {\tt lang/vym\_NEW.ts} to the TRANSLATIONS section of vym.pro
+
+	\item Run Linguist on {\tt vym\_NEW.ts} and do the translation
+
+	\item Run {\tt lrelease} to create {\tt vym\_NEW.qm}
+
+	\item Do a make install to install the new vym and check your translation
+\end{itemize}
+
+If you feel brave, you can also translate the manual. It is written in
+LaTeX, you just have to change the file tex/vym.tex. (Linguist and QT
+are not needed, but it is useful to know how to work with LaTeX and esp.
+pdflatex to create the PDF.) 
+
+Please mail me every translation you have done. I can also give you a
+developer access to the project, if you want to provide translations
+regulary.  
+
+\subsection{New export/import filters}
+\vym supports various kinds of filters. Data can be written directly,
+inserted into templates or it can be written as XML data and then
+processed by XSL transformations. 
+
+Most of the import/export functionality is available in the classes
+ImportBase and ExportBase and subclasses. All of them can be found in
+{\tt imports.h} and {\tt exports.h}.
+
+\subsubsection*{Direct import/export}
+An example for a direct export is the XML export. This method touches
+the implementation of nearly every object of \vym, so whenever possible
+you should better use a XSL transformation instead.
+
+If you still want to know how it is done, start looking at 
+{\tt MapEditor::saveToDir} in {\tt mapeditor.cpp}.
+
+\subsubsection*{Templates}
+Templates have been introduced to export to opendoc format used e.g. by
+Open~Office. While I read the spec ($>$ 500 pages) about the format\footnote{
+\href{http://www.oasis-open.org/}{http://www.oasis-open.org/}}\ 
+I had the feeling that I did not want to write the export from scratch. 
+It would be too complex to adapt the styles to your own wishes, e.g. the
+layout.
+
+Instead I analyzed existing Open~Office documents. I found out that
+there are lots of redundant bits of information in a standard
+presentation, for example each list item is contained in its own list.
+In the end I came up with the default presentation style, which still
+could be simplified, just in case you have free time\ldots
+
+The existing templates are still work in progress, before you spent too
+much time developing your own style, please contact me.  Basically the
+following steps are needed to build your own style:
+\begin{enumerate}
+	\item Create an example in Open Office. Use a title, authors name,
+	page heading etc.\ which you can easily grep for in the output file.
+	
+	\item Unzip  the Open Office document into a directory.
+
+	\item The main file is called {\tt content.xml}. All data is in one
+	single line. You can split the XML tags using the script {\tt
+	scripts/niceXML}, which is part of the \vym distribution.
+
+	\item Copy the output of {\tt niceXML} to {\tt
+	content-template.xml}.
+
+	\item Looking closer you will find lots of unused definitions, for
+	example of styles. You can delete or simply ignore them.
+
+	\item Try to find your title, authors name. \vym will replace the
+	following strings while exporting:
+	\begin{center}
+	\begin{tabular}{lp{4cm}}
+		{\tt <!-- INSERT TITLE -->}		& title of map \\
+		{\tt <!-- INSERT AUTHOR-->	}	& author \\
+		{\tt <!-- INSERT COMMENT -->}	& comment \\
+		{\tt <!-- INSERT PAGES-->}		& content of map \\
+	\end{tabular}
+	\end{center}
+	The content itself is generated in a similar way by inserting lists
+	into {\tt page-template}. Here the following substitutions are made:
+	\begin{center}
+	\begin{tabular}{lp{7cm}}
+		{\tt <!-- INSERT PAGE HEADING-->}		& heading of a page
+		(mainbranch or child of mainbranch, depending on the use of
+		sections) \\
+		{\tt <!-- INSERT LIST -->	}	& all childs of the branch above \\
+	\end{tabular}
+	\end{center}
+\end{enumerate}
+Currently images are exported and notes just will appear as text
+without formatting and colors.
+
+
+
+
+\subsubsection*{XSL Transformation}
+\vym uses XSL transformations while exporting (e.g. XHTML) and importing
+data (e.g. KDE bookmarks). There is a little code needed to provide the
+GUI, the rest is done using the {\tt .xsl} stylesheet and calling the
+{\tt xsltproc} processor, which is part of libxslt, the XSLT
+C  library  for  GNOME.
