Designer includes a number of options
that support screen readers. For each field object in a form, you
can specify one of several settings for screen reader text:
Custom screen reader text, which you set in the Accessibility
palette
Tool tips for objects, which you set in the Accessibility
palette
Captions for fields
Names of objects, as specified in the Name option in the
Binding tab
The settings determine the information that screen
readers read for objects on PDF forms. Only one setting is spoken
for each object.
When the form is saved as tagged PDF, Designer
searches the form for these settings. The default search order is
Custom Text, Tool tip, Caption, and Name. You can override this
default order by using the Screen Reader Precedence option in the
Accessibility palette.
 You can dynamically
populate a tool tip and custom screen reader text with values from
a data source. Note: Tool tips appear at run
time when the user hovers the pointer over an object. The settings
on the Accessibility palette have no effect on objects when the
form is rendered as a PDF form.
- Role
- Determines how screen readers interpret the subform, table,
selected row in a table, list, heading, or heading level:
- Table
- Assigns the role of a table to the selected subform. When
the user navigates to this subform, most screen readers identify
it as a table and indicate the number of rows and columns.
- Header Row
- Assigns the role of a header row to the selected subform
or table row. When speaking the contents of a body row cell, most
screen readers first identify the content of the corresponding cell
in the header row.
- Body Row
- Assigns the role of a body row to the selected subform or
table row. If a cell contains a subform, screen readers typically
speak the content of the corresponding cell in the header row, followed
by the fields in the subform.
- Footer Row
- Assigns the role of a footer row to the selected subform
or table row.
- List
- Assigns the role of a list to the selected subform.
- List Item
- Assigns the role of a list item to the selected subform.
A list item role can only be assigned to a subform that is contained
in a subform that has a List role specified. You cannot define a
table or table row as a list or list item; however, a list item
can contain a table.
- Heading
- Assigns the role of heading to the selected text object.
- Heading Level 1 to Heading Level 6
- Assigns the role of the heading level to the selected text
object.
- (None)
- Specifies a row that conveys information about the table
or its content. The row is not considered to be part of the table;
however, the screen reader will read its contents.
- Tool Tip
- Defines a tool tip for the object. Tool tips appear at run
time when the user hovers the pointer over the object. A screen
reader can read the text entered in this box.
You cannot have
both unique custom tool-tip text and unique custom screen-reader
text for one object. You must choose one or the other. If you want
to use the same text for the tool tip and the text read by the screen
reader, type a tool tip and select Tool Tip from the Screen Reader
Precedence list.
Note: Tool Tip is a dynamic property
for most objects. Dynamic properties are identified by active labels
that have a green underline that you can click to dynamically bind
the property to a data source. To turn active labels on and off,
use the Show Dynamic Properties command in the Object palette menu.
- Screen Reader Precedence
- Indicates which setting the screen reader should read. Only
one setting is spoken for each object:
- Custom
Text
- Reads the text specified in the Custom Screen Reader Text
box. This setting is the default.
- Tool Tip
- Reads the text specified in the Tool Tip box.
- Caption
- Reads the caption specified for the object. The position
of the caption relative to the object does not change the order
in which the screen reader reads the caption. By default, the screen
reader reads the caption if nothing is specified in the Tool Tip
box or the Custom Screen Reader Text box. This setting is the preferred
choice for screen readers.
- Name
- Reads the name of the object, as specified in the Name field
in the Binding tab of the Object palette.
- None
- Disables the custom tool tip or custom screen reader text
for the field.
- Custom Screen Reader Text
- Defines custom text for the selected object. The screen reader
reads the text entered in this box.
You cannot have both
unique custom tool tip text and unique custom screen reader text
for one object. You must choose one or the other. If you want custom
screen reader text to be both the tool tip text and the screen reader text,
type the custom text and select Custom Text from the Screen Reader Precedence
list.
Note: Custom Screen Reader Text is a dynamic
property for most objects. Dynamic properties are identified by
active labels that have a green underline that you can click to
dynamically bind the property to a data source. To turn active labels
on and off, use the Show Dynamic Properties command in the Object
palette menu.
