Unformatted text preview: pertext. Both presentation and use of text information can be greatly enhanced by using hypertext feature. This feature provides great flexibility of structuring and accessing computer-based text information.

The author of a hypertext document determines the actual structure and navigation options (by defining hotwords in the document and linking them to additional text information), and the readers decide the order of navigation according to their individual interests while reading the document online. Generally, hotwords are distinguished from other text displayed on the screen. It may be of different color or font, or the mouse pointer may change into a special symbol (such as a hand) when moved over the hotword.
