Textual regions are similar to graphical regions (described in Graphical Objects, Image Regions, and Sense Regions) in many ways. Like graphical regions, they have attributes such as visibility, selectability, border, and color; they are logically limitless in size and have viewports and windows; and their positions are specified in X Y coordinates. But a textual region is, as its name implies, solely for the purpose of displaying and manipulating large amounts of text. A textual region lets you, for example, compose and edit a memo, present a textual legend alongside a graphical display, or display a table of textual data.
