Inside Macintosh: AppleScript Language Guide / Part 2 - AppleScript Language Reference
Chapter 5 - Objects and References

Reference Forms

A reference form is the syntax, or rule, for writing a phrase that identifies an object or group of objects. For example, the Index reference form allows you to identify an object by its number, as in

word 5 of paragraph 10
AppleScript includes other reference forms for identifying objects in applications. Table 5-1 summarizes the reference forms you can use to identify objects. Each section that follows includes a brief explanation of the reference form, a syntax summary, and examples of how to use the reference form to specify application objects. The Filter reference form is described in more detail in "Using the Filter Reference Form," which begins on page 140.
