Specify tab order
To create user friendly and accessible forms, it is necessary to assign a usable tab order. Users can navigate through the form fields without using
a pointing device. Pressing the Tab key shifts the focus to the next logical field.
There are two methods of specifying a tab order in a tagged PDF:
Use the Articles panel (Windows > Article) to specify a custom tab order
Choose Object > Interactive > Set Tab Order.
Use Articles to specify tab order
Use the Articles panel to specify tab order
1. Open the Articles panel (Window > Articles).
2. Drag the form fields to the Articles panel.
3. In the articles panel, drag to reorder the fields in the required order.
To enable screen readers to use the specified order, from the Articles panel menu, enable Use for Reading Order in Tagged PDFs. Remember
to enable the Create Tagged PDF option while exporting the PDF.
Use Structure to specify tab order
1. Choose Objects > Interactive > Set Tab Order.
2. Click Move Up or Move Down to arrange the items in the desired tab order.
While exporting to interactive PDF, enable Use Structure for Tab Order in the PDF Export dialog box.
