<title
>&kde; Help System</title>
	
<para
>The &kde; help system is designed to make accessing the common &UNIX; help systems (<application
>man</application
> and <application
>info</application
>) simple, as well as the native &kde; documentation (&XML;). </para>
	
<para
>All base &kde; applications come fully documented, thanks to the efforts of the Documentation team. If you would like to help, please write to the Documentation coordinator, Lauri Watts, at <email
>lauri@kde.org</email
> for information. No experience is required, just enthusiasm and patience. </para>

<para
>If you would like to help translating &kde; documentation to your native language, the Translation coordinator is Thomas Diehl, <email
>thd@kde.org</email
>, and he would also welcome the help. More information, including the coordinators for each language team, can be found on the <ulink url="http://i18n.kde.org"
>Internationalisation web site</ulink

>Contact</link

<para
>&khelpcenter; is an integral part of the &kde; Base installation, and is installed with every copy of &kde;. It can be found in the tdebase package, and is available from the &kde-ftp;, or will be found in your operating system tdebase package. </para>

<title

<para>
Searching requires you have the <application

application installed.  Information on installing and configuring the
search index is available in the document.  Configuration of the search
index is performed in the &kcontrol;, by choosing
<menuchoice
><guisubmenu
>Help</guisubmenu
><guimenuitem
>Index</guimenuitem
></menuchoice
>,
and detailed help is available from this module.
</para>

<para>
For the purposes of this document, we'll assume you already have this set
up and configured.
</para>

<para>
Searching the help files is fairly intuitive, enter the word(s) you wish
to search for in the text box, choose your options (if any), and press
<guibutton
>Search</guibutton
>.  The results display in the viewer pane
to the right.

<para>
Choose how to search for multiple words.  If you choose
<guilabel
>and</guilabel

terms are included in the page. <guilabel

if <emphasis

<guilabel

Boolean syntax lets you use the operators <literal

<sect2 id="man-and-info">
<title
>The <application
>Man</application
> and <application
>Info</application
> sections</title>

<para
>Man pages are the standard &UNIX; manual pages, and have been in use for many years on many operating systems. They are extremely thorough, and are the very best place to get information about most &UNIX; commands and applications. When people say <quote
>RTFM</quote
>, the Manual they are referring to is very often the man page.</para>

<para
>The man pages are not perfect. They tend to be in depth, but also extremely technical, often written by developers, and for developers. In some cases this makes them somewhat unfriendly, if not downright impossible for many users to understand. They are, however, the best source of solid information on most command line applications, and very often the only source.</para>

<para
>If you've ever wondered what the number is when people write things like man(1) it means which section of the manual the item is in. You will see &khelpcenter; uses the numbers to divide the very many man pages into their own sections, making it easier for you to find the information you're looking for, if you're just browsing.</para>

<para
>Also available are the Info pages, intended to be a replacement for the man pages. The maintainer of some applications no longer update the man pages, so if there is both a man page and an info page available, the info page is probably the most recent. Most applications have one or the other though. If the application you are looking for help on is a &GNU; utility, you will most likely find it has an info page, not a man page.</para>

<sect3 id="navigation">
<title
>Navigating inside the <application
>Info</application
> pages</title>

<para
>Info documents are arranged hierarchically with each page called a node. All info documents have a <guilabel
>Top</guilabel
> node, &ie; the opening page. You can return to the <guilabel
>Top</guilabel
> of an info document by pressing <guilabel
>Top</guilabel
>.</para>

<para
><guibutton
>Prev</guibutton
> &amp; <guibutton
>Next</guibutton
> are used to move to the previous/next page at the current level of the hierarchy.</para>

<para
>Clicking on a menu item within a document moves you to a lower level in the hierarchy. You may move up the hierarchy by pressing <guibutton
>Up</guibutton
>.</para>

<para
>Man is treated similarly to info, with the section index being the Top node and each man page on the level below. Man entries are one page long.</para>

<sect2 id="kde-glossary">
<title
>The &kde; glossary</title>

<para
>The glossary provides a quick reference point, where you can look up the definitions of words that may be unfamiliar to you. These range from &kde; specific applications and technologies, through to general &UNIX; computing terms. </para>

<para
>In the left hand pane you will see a tree view, with two choices: <guilabel
>Alphabetically</guilabel
