8.1.a navindex and accesskey (non-normative)
This test case is non-normative and assumes that navindex attributes
will be recognized and interpreted as described in section 4.3.1 of the specification.
Navigation order must be the Name input first, the Item input second, and the Quantity input third.
Keyboard users can use the Tab key to test the navigation order.
The input controls are also set to use access keys. Keyboard users can hold down the Alt key, the Shift
key, and the key in parentheses in the labels of the input controls to jump directly to an input control.
