To display a toolbar, press ALT and then SHIFT+F10.) to insert form fields (form field: In a form, a location where a particular type of data, such as a name or address, is stored.) in a form (form: A document that contains fill-in blanks, or form fields, in which you enter information. For example, you can create an online registration form in Microsoft Word that uses drop-down lists from which users can select entries.), you can use this procedure to change the behavior of the fields.
