Using Input Fields
When you tab to an input field that is enabled, you can enter data as necessary.
For JAWS users: When you tab to a single input field, JAWS announces the label of the input field, the short description if one is available, how to access input help if it is available, and whether the field is disabled (unavailable).
When you tab to an input field that is the first in a series of input fields associated with a single label, JAWS announces the field label and how to access input help if it is available, then it tells you that the label has X number of input fields associated with it and that this is the first input field. It also announces the short description if there is one, and whether the field is disabled (unavailable). For all subsequent input fields associated with that label, JAWS announces only which number of input field it is (second, third, and so on).
If there were two input fields with a single, common label "country," when you tab to the first input field, JAWS would announce "country this field has two input fields first input field edit type a text." When you tab to the second input field, JAWS would announce "second input field edit type a text."
