Help System Handbook

Help System
The help system is designed to make accessing the common help systems (man and info) simple, as well as the user documentation of applications including from the community ().
All applications (including ) from the community come fully documented, thanks to the efforts of the Documentation team. If you are interested in helping with the documentation efforts, join the mailing list and write to the team at kde-doc-english@kde.org. No experience is required, just enthusiasm and patience.
If you would like to help translating documentation to your native language, review the information, including coordinators for each language team, on the Localization web site.

Installation
is a part of the . It can be found on the download site of the project, or will be found in your operating system's package.

Invoking Help
can be called in several ways:
From the Help menu 	 The most common will probably be from within an application. Choose F1 Help Application Handbook to open that application's handbook.
From the Application Launcher 	 Choose the big K in your panel, and select Help from the Applications tab or type help followed by selecting Help. This will open with the default start page.
From the command line 	 may be started using a to display a file. s have been added for info and man pages also. You can use them as follows:
An application help file 	 khelpcenter help:/kwrite
Opens the help file, at the contents page.
A local 	 khelpcenter file:/usr/local/src/qt/html/index.html
A Man page 	 khelpcenter man:/strcpy
An Info page 	 khelpcenter info:/gcc
Invoking khelpcenter with no parameters opens the default start page.

The interface
The interface consists of two panes of information.
The toolbar and menus are explained further in The menus and toolbar.
Documents contain their own navigation tools, enabling you to move either sequentially through a document, using Next, Previous, and Contents links, or to move around in a less structured manner, using hyperlinks.
Links can take you to other parts of the same document, or to a different document, and you can use the Back (Left pointing arrow) or Forward (Right pointing arrow) icons on the toolbar to move through the documents you have viewed in this session.
The two panes display the contents of the help system, and the help files themselves, on the left and right respectively.

The Contents Pane
The contents pane in is displayed on the left hand side of the window. As you might expect, you can move the splitter bar, to make sure you can comfortably read the contents of either pane.
The contents pane is further divided into three tabs, one containing a tree view showing all the help information is aware of, and the other contains the glossary of terms. On the third tab you can configure the Search Options.

The Contents Tab
The Contents tab contains the following default top level entries in the tree view:
Fundamentals 	 The Fundamentals introduce you to the many features of the and and describe many common tasks you can perform in all .
Plasma Manual 	 The Manual is the documentation for the .
Online Help 	 A page with links to online help and additional information provided by the community.
Application Manuals 	 Native application documentation. All applications have documentation in format, which are converted to HTML when you view them. This section lists all the applications with a brief description and a link to the full application documentation.
The applications are displayed in a tree structure that echoes the default structure of the K menu, making it easy to find the application you are looking for.
Settings Modules entities 	 Provide a list of links to various modules in the application or to modules for , Filemanager or Browser.
KInfoCenter Modules 	 Contains a list of links to various KInfocenter modules documentation.
Kioslaves 	 Contains a list of links to various KIO modules documentation.
manual pages 	 man pages are the traditional on-line documentation format for systems. Most programs on your system will have a man page. In addition, man pages exist for programming functions and file formats.
Scrollkeeper 	 Additional non- documentation installed on your system.
Browse Info Pages 	 TeXinfo documentation is used by many applications, including gcc (the C/C++ compiler), emacs, and many others.

The Search Options tab
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 Search. The results display in the viewer pane to the right.
Search is not case sensitive, uppercase and lowercase characters are considered the same. For example, if you search for Shortcut, results that contain shortcut will be returned as well.
The options available are:
Method 	 Choose how to search for multiple words. If you choose and, results are returned only if all your search terms are included in the page. or returns results if any of the search terms are found.
If your searches are not returning the results you expect, check carefully you haven't excluded the wrong search term with an erroneous setting.
Max. results 	Determines the maximum number of results returned from your search.
Scope selection 	This is used to select the sections where the search will be done. The available options quickly select the most common option, while Custom allows one to select single sections.

The Man and Info sections
Man pages are the standard 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 commands and applications. When people say RTFM, the Manual they are referring to is very often the man page.
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.
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 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.
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 utility, you will most likely find it has an info page, not a man page.

Navigating inside the Info pages
Info documents are arranged hierarchically with each page called a node. All info documents have a Top node, the opening page. You can return to the Top of an info document by pressing Top.
Prev & Next are used to move to the previous/next page at the current level of the hierarchy.
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 Up.
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.

The glossary
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 specific applications and technologies, through to general computing terms.
In the left hand pane you will see a tree view, with two choices: Alphabetically or By Topic. Both contain the same entries, sorted differently, to allow you to quickly find the item of interest.
Navigate down the tree views to the left, and items you select will be displayed on the right.

The menus and toolbar
has a very minimal interface, allowing you to concentrate on getting help rather than learning how to use the help browser.
The icons available to you in the toolbar are as follows:
