Fields are used to insert information about the current document, for example, file name, template, statistics, user data, date, and time.
若您将一个交叉引用作为字段插入，则您在修改文档时不必总是手动调整引用。只需利用 F9 键更新字段，文档中的引用也同时被更新。
Depending on the field type that you select, you can assign conditions to certain functions. For example, you can define a field that executes a macro when you click the field in the document, or a condition that, when met, hides a field. You can also define placeholder fields that insert graphics, tables, frames and other objects into your document when needed.
DocInformation fields contain information about the properties of a document, such as the date a document was created. To view the properties of a document, choose File - Properties.
Variable fields let you add dynamic content to your document. For example, you can use a variable to reset the page numbering.
You can insert fields from any database, for example, address fields, into your document.
