Authors of Web pages can specify the TAB order for form controls by using the "Tabindex" HTML attribute. JAWS moves through the controls in this specified order when you press TAB or CTRL+INSERT+TAB to move through the form. If the "Tabindex" attribute is not assigned to all fields, JAWS first moves through the items with a "Tabindex" assigned, then moves through the other form fields and links in the order they appear on the page.
The form on this page is arranged in a table with fields for billing information in the left column and fields for shipping information in the right. The "tabindex" attribute is used to specify the order of the controls when you move through the form by pressing TAB or SHIFT+TAB. JAWS first moves through the fields for billing information, then through the fields for shipping information, and finally to the submit and reset buttons. If the "Tabindex" attribute had not been used, JAWS would move from the first field in the left column to the first field in the right, then to the field in the left column of the second row, then to the field in the right, and so on. The "Tabindex" attribute helps to organize the form while maintaining the visual appearance.
