The PCMagazine article (second page) [AutoWhat? 2] explains that each input field in a Web-based form has an internal name that identifies the field to the system. The field also has a friendly display label that identifies it to you, the user. The internal name doesn't have to relate to the field's purpose, but it usually does. For example, a field labeled First name might have an internal name such as FirstName, first_name, or fname. When you submit the information in the form, Internet Explorer records each input field's data in the Registry in a list associated with the particular field name. The next time you start typing in a field that has the same internal name, whether on the same Web page or a different one, IE will pop up a list of previous values that begin with the text you've typed up to that point. You can click on one of the items to select it, or press the Down Arrow to select it and press Enter. If you click in a blank input field and press the Down Arrow, IE will list all data associated with that field. Under Windows 9x (95/98/Me), the internal field names are visible in the Registry, but the data is encrypted. Under Windows NT (NT 4.0/2000/XP), even the field names are inaccessible.
