Hypertext systems are great. But there is more: Some help systems provide special search abilities and navigation techniques to give the user tools to find solutions for his problems.<\/p>\n

On this page we present some of these systems. We want to describe functionalities and techniques that can be relevant and inspiring for hypertext systems.<\/p>\n

The MS-DOS HELP System<\/h4>\n

Starting with MS-DOS 6.x Microsoft introduced an extended help system working with QBASIC. The HELP command provides hyperlinks and other features.<\/p>\n

Texinfo\/man\"The<\/a><\/h4>\n

The help systems of Unix-like systems provide a web of connected documentation. There are differences between Texinfo and man, but the both are very similar in handling navigation and search. With man<\/em> navigation does not happen interactively, you have to call the program to search for information (e.g. man -k man<\/code>) and then call the program again to read the information (e. g. man man<\/code>). The Texinfo reader info<\/em> provides an interactive navigation method. There are additional readers and exporters for both systems that provide more navigational features.<\/p>\n

Vim Help System\"Vim<\/a><\/h4>\n

The vim online help (:help<\/code>) provides not just helpful information but a navigational system. Users can follow links and jump back. They can search for pages and for content. Although the help files are plain text they use a special markup language to visualize different types of information in different ways.<\/p>\n
