Answer 1

Why is setting tab order important?
When visitors fill out a form, they can use the [Tab] key on the keyboard rather than a mouse to move from field to field. For some visitors, this is simply a matter of preference, but for visitors with certain disabilities, using the keyboard is the only means by which they can navigate the form.
How can you change the tab order?
When you modify a form field's properties, you have the option of setting the tab order. By assigning the first field a tab order of 1, the second a tab order of 2, and so on, you ensure that keyboard users can complete the form in a logical manner. It's important to set the tab order on all fields if you set it on one; otherwise, keyboard users will not proceed through the form as you intended.
What will the tab order be if you do not assign a tab order?
If you don't assign a tab order to any of the fields, visitors who use the [Tab] key will move through the field in the order in which the fields appear in the HTML code. Depending on how your form is laid out, this can work just fine.
How can you test the tab order?
If you're not sure whether you need to assign a tab order, preview the page in a browser, then press [Tab] to move to each field on the form. If you move through the fields in a different order than makes sense, it's a good idea to set the tab order for each field.
