\section{Introduction}

\subsection{What is a \vym map?}

A \vym map (abbreviated below as {\em map}) is a tree like structure:

\begin{center}

	\includegraphics[width=12cm]{images/example1.png}

\end{center}

Such maps can be drawn by hand on a sheet of paper or flip chart and help to

structure your thoughts. While a tree like structure like the illustration above can be

drawn manually \vym offers much more features to work with such maps.

\vym is not just another drawing software application, 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 pieces of information like a complete

email by a simple mouse click.

Once you have finished collecting and organising your ideas, you can

easily generate a variety of outputs including for example a presentation in Open~Office based on a {\em map}.

\subsection{Why should I use {\em maps}? Time, Space and your Brain.}

\subsubsection*{Space}

A {\em map} can concentrate very complex content in a small space such as 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, colours and

keywords in a map, often called {\em anchors}).  It is a technique to help

organize the way you think and stimulate your creativity: It can help you by developing, sorting and helping to memorise your ideas. 

\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 with

other things -- a {\em map} makes use of those connections and stimulates

new asccociations. 

\subsubsection*{Your Brain}

In 1960 Prof. {\sc Roger Sperry} discovered that both hemispheres

of the human brain undertake 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 analysing 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 western society we have learned to mainly rely on our

left side of the brain, the "rational" one. In other cultures, such as the native americans and other "old" cultures, the right

side is much more important. {\em Map} are just one way to stimulate the

other side and make use of additional resources we all have.

\subsection{Where could I use a {\em map}?}

Here are some examples, how you can use those {\em maps}

\begin{itemize}

    \item to prepare articles, papers, books, talks, \ldots

    \item to sort complex data

    \item to memorize facts, peoples names, vocabulary, \ldots

    \item to sort emails, files and bookmarks on your computer

    \item to moderate conferences

    \item to brainstorm solutions to problems

    \item to record the tasks when planning a project

\end{itemize}

\subsection{What you shouldn't do with a {\em map}...}

A {\em map} drawn by somebody shows the way that the author thinks. There is

no question of right or wrong in the way it is drawn, so there is no way to criticise

it. "It is, what it is" ({\sc F.~Lehmann}).The tool will be of considerable use to the author and only very limited use to anyone else. 

However, when groups share in creating a {\em map} all of the group will benefit from its use. An example of such use is when a Tutor develops a {\em map} with a group of students during instruction. Another group use is when a Project leader gathers a group of specialists to help {\em map} the tasks that will be required to deliver a project.

\subsection{Internet Ressources} 

A good starting point to learn more about Mindmaps 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{The Concept of the \vym application}

%TODO may add a general introduction here...

\subsection{The Mainwindow and its satellites} \label{satellite}

\vym comes with several windows, the central one being the {\em

mapeditor}.

More windows, each having a special purpose, can be opened and arranged

around the mainwindow\footnote{

	The advantage of having separate window instead of integrating them

	in a combined workspace is flexibility in arranging the windows. For

	example I usually have the {\em noteeditor} "behind" the {\em

	mapeditor}. On Linux my windowmanager (KDE) allows me to enter text

	into a small visible corner of the {\em noteeditor} withour clicking

	the mouse button in it. I just push the mouse around to set the

	window focus, a concept which is useful also working with 

	\href{http://www.gimp.org}{http://www.gimp.org}.

}. 

The image below shows the {\em mapeditor}

together with the often used {\em noteeditor}: 

\begin{center}

	\includegraphics[width=8cm]{images/windows.png}

\end{center}

Most of the time 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}

Here is a list of the available satellite windows:

\begin{itemize}

	\item Noteeditor (see \ref {noteeditor})

	\item Historywindow (see \ref{historywindow})

	\item Branch Property Window (see \ref{propwindow})

\end{itemize}

\subsection{Menus and Context menus}

At the top of each window you will find the menubar. The options provided there

are similar to those you are probably used to 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 display the state of selected objects in the map. For example a

branch may show certain {\em flags}, the corresponding flags are also

set in the toolbar. 

Note that you can reposition all toolbars by simply grabbing and

dragging them with the toolbar handle to a new position. 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.  Or just

insert it again at its original position. Also hiding some of the

toolbars is possible by right-clicking on the toolbar handle.

\subsection{Maps}

The  {\em map} itself has always a {\em mapcenter}.  The

mapcenter has {\em branches} radiating out from the centre just like the trunk of a tree. Each branch in turn may have branches again.

\begin{center}

	\includegraphics[width=10cm]{images/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

key 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]{images/default-flags.png}

\end{center}

These are called {\em flags} and can be used to mark branches in the

{\em 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 note is attached to 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 reset and vice

versa. You can change this default behaviour in the settings menu.

\section{Mapeditor} \label {mapeditor}

\subsection{Start a new map}

After \vym is started two windows will open: the {\em mapeditor} and the {\em 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 be highlighted 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 menu by clicking with the

	right mouse button (CTRL-Click on Mac) onto the

	mapcenter and choose Add \ra Add branch 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 in handy to be able to add a new branch above or below the current

one. 

\begin{itemize}

	\item Use \key{Shift-Ins} to add a branch above the selected one or... 

	\item \key{Ctrl-Ins} to add one below. 

\end{itemize}

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 tap

\key{\la} or \key{\ra} to move 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{Home} and \key{End} to select the first and last branch.

\subsubsection*{Panning the view of a map}

While adding more and more branches the size of the map may become

larger than the mapeditor window. You can use the scrollbars on the

right and the bottom of your mapeditor window to scroll the view up or down or left or right. It is easier to just scroll using the left mouse button: Click anywhere on the {\em canvas} itself. Choose an empty space somewhere between the branches. The

mouse pointer will change from an arrow to a hand, now move or drag the visible

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.

\subsubsection*{Zooming the view of a map}

Working with huge maps, the {\em zoom}-function comes in handy: You can

use 

\begin{itemize}

	\item from the menu: View \ra Zoom in, View \ra Zoom out, View \ra reset Zoom.

	\item the toolbar buttons 

		\begin{center}

			\includegraphics[width=3cm]{images/zoom-buttons.png}

		\end{center}	

\end{itemize}	

Clicking the crossed magnifying lens icon will reset 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]{images/find-window.png}

\end{center}	

The find function will search for, the text you enter here, in all the branch headings and also in the associated notes. Everytime you press the "Find"-button it will look for the next occurence, which will then be selected automatically. If the search

fails, a short message "Nothing found" will appear for 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 child branches would make

it very hard to keep an overview over the whole map. You can hide all

the children of a branch by {\em scrolling} it -- this function is often called {\em folding}. Think of the whole subtree as painted onto a

broadsheet newspaper. You can scroll or fold the paper to a small roll, leaving just

the headline visible.

To scroll or unscroll a branch and its children,

\begin{itemize}

	\item press either the \key{Scroll Lock} key or the \key{S}

	\item press the middle-mouse button or

	\item choose the scroll icon 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 no

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 pressing \key{F2}

	\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]{images/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 can also be used to reorder branches in a map.

\subsection{Colours and Images - Using the right side of your brain}

\subsubsection*{Change colour of a heading}

You can also use colours to add more information to a map, e.g. use

red, green and more colours to prioritize tasks. Again you can

\begin{itemize}

	\item use the menu and choose e.g Format \ra Set Color

	\item use the toolbar

		\begin{center}

			\includegraphics[width=3cm]{images/color-buttons.png}

		\end{center}	

\end{itemize}

The first button (black in the graphic above) shows the current colour.

Clicking on it let's you choose another colour. You can also "pick"

another colour by selecting a branch with the desired colour and using the

"pick colour" button. Both of the icons showing a palette actually apply

the current colour to the selected branch. While the first one just

colours the heading of the selection, the last one also colours all the

children of the selected branch.

%tipp

A very useful function is the "copy colour" using the mouse: Select the

branch which should get the new colour, then press \key{Ctrl} and

simultanously click with left-mouse on another branch to copy its colour

to the first one. Here the children of the selection also will get the new

colour, if you just want to colour the selection itself, additionally

press \key{Shift}.

\subsubsection*{Use flags}

\vym provides various flags. They are usually displayed 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]{images/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. So, to remove a flag from a branch, select the branch and then click the highlighted flag on the toolbar.

At present \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 an image to a branch by opening the context menu of the

branch. Right click the selected branch, choose "Add Image". A

dialog window enables 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, a preview of the

image is displayed. 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 in the {\em property window} (see

\ref{propwindow}). 

Alternatively, you can use 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 that cloud.

\subsection{Design of map background and connecting links }

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 on the canvas, which will open a context menu

\end{itemize}

\subsubsection*{Background }

The colour is set (and also displayed) as "Set background colour".

Alternatevily you can set an background image, though this is not

recommended in general. Working on the map becomes slow and the image

currently cannot be positioned freely.

\subsubsection*{Link colour}

Links connecting branches can be coloured in one of two ways:

\begin{itemize}

	\item use the same colour for the heading and for the branch link line.

	\item use {\em one} colour for all links and choose different colours for the branch headings text. The default colour for branch link lines is blue.

\end{itemize}

The latter can be set with "Set link colour". Check or uncheck the "Use

colour of heading for link" option to toggle between 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 apply to links starting at the mapcenter, link lines for the rest

of the map are 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 to another one. Those are called {\em XLinks} and are explained

in section~\ref{xlinks}.

\subsubsection*{Webbrowser}

Modern Webbrowsers like {\tt konqueror and Firefox} are able to display various

types of files, both local or on the internet. To enter the URL of

any document, right-click  onto a branch to open the contextmenu then 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 launched.

\begin{center}

	\includegraphics[width=0.5cm]{images/flag-url.png}

\end{center}

For more information on working with bookmarks and webbrowsers see

section \ref{bookmarks}.

In the context menu there is also an option to open all URLs found

in the selected subtree of the map. That's useful to simultanously open

a collection of URLs in the webbrowser, especially if the browser can

open them in tabs (like Konqueror).

\subsubsection*{\vym map}

To link to to another map right click on a branch and choose "Edit \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]{images/flag-vymlink.png}

\end{center}

Clicking this flag beside the branch heading, 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 right click the branch and select "Delete \vym link".

In the context menu there is also an option to open all vymlinks found

in the selected subtree of the map. That's useful to simultanously open

a collection of related maps.

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 attach more text to 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]{images/noteeditor.png}

\end{center}

This editor displays text associated with a branch selected in the mapeditor. The noteeditor

shows different background colours depending on whether text is associated with a selected branch.

\subsection{States}

Before you can type or paste text into it, you have

to select a branch in the mapeditor. Note that the background colour

of the noteeditor indicates its state:

\begin{itemize}

	\item grey: no text entered yet

	\item white: some text has been entered

\end{itemize}	

In the mapeditor itself, to signal 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. This is illustrated in the lower branch on the right hand side:

\begin{center}

	\includegraphics[width=8cm]{images/branches-flags.png}

\end{center}

\subsection{Import and export notes}

The note is always saved automatically within the \vym map itself.

Nevertheless sometimes it is nice to import a note from an external file

or write it. In the Note Editor 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.

\subsection{RichText: Colours, paragraphs and formatted text}

\vym supports formatted text (QT Rich Text) in the noteeditor since

version 1.4.7.  Colours and text attributes (e.g. italic, bold) can be

set with the buttons above the text.  The text itself is divided into

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 switch them quickly}

The noteeditor is designed to be used for simple notes, not really as a full

featured word processor. Because of many requests \vym supports 

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]{images/formatfixedfont.png}

\end{center}

In the Settings menu both fonts can be set. The default font can also be toggled between the fixed and variable font by selecting or deselecting the "fixed font is default" menu item.

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 if youy VYM mind map could ever be exported to a web or intranet page 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

\section{Hello world}

This section is about how \vym can interact with other applications.

Many applications can now 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 you make use of another application that 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 (Konqueror etc.) 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 commercial i.e. non free, software application by Mindjet for Windows and the Mac. Both names are registered trademarks by Mindjet. For more information see their website at

\href{http://mindjet.com}{http://mindjet.com}} 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 may not 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]{images/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 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]{images/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 

	\item The full range of templates are not available in all distributions.	

\end{itemize}

Some of the templates make use of {\em sections} i.e sections 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 be 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 may then 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 to use if you wish to create a webpage. To see an example

visit the \vym homepage: 

\href{http://www.InSilmaril.de/vym}{www.InSilmaril.de/vym}

Some explanation on 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 and some other distributions {\tt xsltproc} is installed by

default.}

will be called to process the XML file and generate HTML code.

A dialog allows the user 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 colour the headings in the text part  with the

	same colours used in the \vym 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 an XML file. The

directory is set in a file dialog. If the directory is not empty, you

will be warned and offered choices if you are at risk of overwriting existing 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, for example, a website comprises several combined maps that 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 children, then open

the context menu and choose {\em Save Selection}. This will create a

file with the suffix {\tt .vyp}, which is an abbreviation for \lq vym

part\rq.

\section{Advanced Editing}

\subsection{Properties of an object} 

For any branch you can open a satellite window (see \ref{satellite}):

the {\em property window}:

\begin{center}

	\includegraphics[width=8cm]{images/propwindow.png}

	\label{propwindow}

\end{center}

%FIXME create screenshot

%FIXME explain the tabs

\begin{itemize}

	\item Frame

	\item Link (see \ref{hideunselected})

	\item Layout (see \ref{incimg})

\end{itemize}

\subsection{Changing the history: Undo and Redo}

\vym keeps track of all changes done in a map. The default number of

changes which can be undone is~75. The complete history can be seen in

the {\em historywindow}:

\begin{center}

	\includegraphics[width=8cm]{images/historywindow.png}

	\label{historywindow}

\end{center}

A single step back be undone or redone with \key{CTRL-Z} or \key{CTRL-Y},

or by using the buttons in the toolbar or the {\em historywindow}.

Inside the {\em historywindow}, you can click on a line to unwind all

actions done until that point in time -- or redo all changes by clicking

on the last line.

\subsection{Macros} \label{macros}

Macros have been added to \vym in version~1.9.0. Each function key

\key{F1} to \key{F12} holds a macro, which is executed on the current

selection if the key is pressed. The default macros change the colour of

a subtree or set the frame of a branch:

\begin{center}

	\includegraphics[width=8cm]{images/macros.png}

\end{center}

Each macro is a \vym script, which is executed when the associated key

is pressed. The default location of the scripts can be changed in the

Settings menu. More information on using scripts in \vym is found in

appendix~\ref{scripts}.

\subsection{Bookmarks} \label{bookmarks}

\subsubsection*{Open new tabs instead of new windows}

If you use konqueror as your browser, \vym will remember the konqueror session which

was opened first by \vym. You can also press \key{Ctrl} and click to

open the link in a new tab.

\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 browsers.

\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{Associating images with a branch} \label{incimg}

The default setting for an image is for it to float "freely". Images can be

positioned anywhere on the canvas, but may end up in the same place as other

parts of the map obscuring that part of the map.

The solution is to insert or include them "into" a branch. This can be done via

the property window (see \ref{propwindow}):

\begin{itemize}

	\item Include images horizontally

	\item Include images vertically

\end{itemize}

The image is still positioned relative to its parent branch, but the

heading and border of the branch frame adapt to the floating image, see below: 

\begin{center}

	\includegraphics[width=11cm]{images/includeImages.png}

\end{center}

\subsection{Modifier Modes} 

Modifiers are for example the \key{Shift}- the \key{Ctrl}- ot the \key{Alt}-keys. When

pressed while applying mouse actions, they will cause \vym to use

a "modified" version of the action which usually would be done. 

%\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 key pressed, the first mouse 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]{images/modmodes.png}

\end{center}

The default mode is to copy the colour from the clicked branch to the already

selected branch. The figure above shows the toolbar with the default modifier 

selected. The second modifier

let's you easily copy a whole branch with a single click. The third

modifier lets you create links between branches called {\em xLinks}.

They will be explained in the next section \ref{xlinks}.

\subsection{Hide links of unselected objects} \label{hidelink}

Sometimes it would be useful to position a branch freely, just like a

mainbranch or an image. This is possible for all

branches, you can use a mainbranch and hide its connecting link to the

mapcenter or hide the link between a child branch and its parent. This can be used e.g. for legends or a collection of vymLinks

pointing to other maps:

\begin{center}

	\includegraphics[width=9cm]{images/hiddenlink.png}

\end{center}

To hide the link between a branch and its parent open the

\ref{propwindow} and check "Hide link if object is not selected" on

"Link" tab.

\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 can not be displayed on the same

visible area of the {\em mapeditor} window. The following example map 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]{images/xlink.png}

\end{center}

Note that a xLink which points to a branch that is not visible (because

it is scrolled), is just shown 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 the toolbar icon or pressing

\key{L}). Select the branch, where the xLink should start. Press the

modifier key \key{Ctrl} and then click on the selected branch where the

link should start and drag the mouse pointer to the branch where the link is to end. (The link is drawn to follow the mouse pointer). When you release the mouse over a branch the xLink becomes permanent.

\subsubsection*{Modify or delete a xLink}

First select a branch at either end of the xLink. Then open the context

menu 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

colour, width and also delete the xLink.

\subsubsection*{Follow a xLink}

In a complex \vym map it sometimes comes in handy to be able 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 children. The children 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 Add Map (Insert)}. For the import you can choose

between {\em Add Map (Insert)} and {\em Add Map (Replace)}: The imported

data will be added after the selected branch.

\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
