Patent US 5,285,526

A method is described for manipulating commonly used elements within a structured document. The method takes advantage of a user's intent in selecting certain keystrokes to complete a task. By making assumptions on the user's intent at the current position within the document and dynamically changing the functions of keystrokes based on those assumptions, the method allows the user to quickly and easily manipulate the commonly used elements of a structured document without having to specify any tag names or markup language, and without having to understand the rules for creating a structured document.
