Task:

Giving focus to elements in an order that follows sequences and relationships within the content.

Some Web content must support sequential navigation. For example, a person using a keyboard or keyboard interface to complete an online form typically uses the tab key to move from one input element to the next item on the form. Each time the user presses the tab key, another element receives focus. The user's next action will affect the item that has focus. In some cases it may be necessary to specify the order in which the focus will move from item to item, because the default order is not logical.
