MACROMEDIA FLASH 8-USING FLASH Use Manual page 519

In the Accessibility panel, you can turn off automatic labeling if it is not appropriate for your
document. You can also turn off automatic labeling for specific objects within your
document. See "Turning off automatic labeling for an object and specifying a name"
on page 521.
Providing a name for an object
If you do not want to use automatic labeling for the entire application, you can turn it off and
provide names for the objects in the Accessibility panel. If you have automatic labeling turned
on, you can also select specific objects and provide names for the objects in the Name text box
in the Accessibility panel so that the name is used instead of the object text label.
When a button or input text field doesn't have a text label, or when the label is in a location
that Flash Player can't detect, you can specify a name for the button or text field. You can also
specify a name if the text label is near a button or text field, but you don't want that text to be
used as that object's name.
For example, in the following figure, the text that describes the button appears outside and to
the right of the button. In this location, Flash Player does not detect the text, and it is not
read by the screen reader.
To rectify this, open the Accessibility panel and select the button and enter the desired name
(for example, "left arrow") and description (for example, "Go to previous page") in the Name
and Description text boxes, respectively. To prevent repetition, make the text object
inaccessible.
An object's accessibility name is unrelated to the ActionScript instance name or
ActionScript variable name associated with the object. For information on how
ActionScript handles instance names and variable names in text fields, see "About text
field instance and variable names" in Learning ActionScript 2.0 in Flash. (This information
generally applies to all objects.)
