Many
users use the Tab key to move between fields and buttons in a form
instead of using the mouse. Designer lets you set the tabbing order
between objects in a form.
Tabbing order is important for interactive forms and forms that
have a fixed layout. For interactive forms, the tabbing order affects
the end user’s experience when filling the form.
For both interactive and non-interactive forms, tabbing order
is critical if your forms need to be accessible to users with vision
or mobility impairments. These users typically do not use a mouse
to navigate through the form, so they depend on the keyboard keys
and a good tabbing order sequence to ensure that they have full
access to all the fields on the form.
Accessible forms require a tabbing order, whether the form is
interactive or designed for print. Additionally, a screen reader
will read the form in geographic order, which in Designer is set
when you use the default tabbing order.
Designer automatically sets a default tabbing order for each
form. This tabbing order can be easily changed to better reflect
the logical flow of the form and to accommodate particular user
requirements.
