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. It generalizes the
concepts of "footnote" and "cross reference" of traditional information (or
document) organization and allows users to obtain information just by clicking on
an anchor (a word or phrase linked to another document) within a document. An
anchor is often called a "hotword". This means that if the user wants more
information about a particular hotword, he/she can select that hotword (usually
with a mouse pointer) and open a window with additional text explaining that
word or phrase.
Figure 19.1 shows a typical structure of hypertext documents in which information
units are stored in a network of nodes interconnected by links. This type of
information structuring allows nonsequential navigation within the information
space according to individual needs. 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.
This makes it easier for the user to identify which words have associated links
with more information. Otherwise, the user can waste a lot of time clicking on
words that have no other associated information.
5. Text importing and exporting. The task of creating a text document can often be
greatly simplified if the document preparation software has text importing feature.
This is because some of the text you want to incorporate in your document may
already exist as a file created by...
