Navigation in the help system is achieved by clicking on links within the documents and by using the options in the Goto menu and the toolbar.
If the help system is started without a starting location supplied on the command line, the Contents are displayed. The first section consists of general information on the KDE project. The second section section deals with specific applications/command documentation.
The application and system documentation are divided into three sections:
Native KDE application documentation. All KDE applications have documentation written in DocBook, then converted to HTML. This section lists all the KDE applications with a brief description and a link to the full application documentation.
UNIX man pages are the traditional on-line documentation format for unix systems. Most programs on your system will have a man page. In addition, man pages exist for programming functions and file formats.
TeXinfo documentation is used by many GNU applications, including gcc (the C/C++ compiler), emacs, and many others.
These are the history commands. Back moves back to the previous page you visited, while Forward moves you to the next page that you visited. The history list is currently up to 50 locations deep, though this will probably be configurable in future releases.
You will recognise these commands if you have used info previously. Info documents are arranged hierarchically with each page called a node. All info documents have a Top node, i.e. the opening page. You can return to the Top node 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.
