Make an entire Flash application accessible

After a Flash document is complete and ready to be published or exported, make the entire Flash application acces-

sible.

1 Deselect all elements in the document.

2 Select Window > Other Panels > Accessibility.

3 Select Make Movie Accessible (the default setting) to expose the document to screen readers.

4 Select or deselect Make Children Accessible to expose or omit any accessible objects in the document to screen

readers.

5 If you selected Make Movie Accessible in step 2, enter a name and description for the document as needed.

6 Select Auto Label (the default setting) to use text objects as automatic labels for accessible buttons or input text

fields contained in the document. Deselect this option to turn off automatic labeling and expose text objects to screen

readers as text objects.

Viewing and creating tab order and reading order

The two aspects to tab indexing order are the tab order in which a user navigates through the web content and the

order in which things are read by the screen reader, called the reading order.

Flash Player uses a tab index order from left to right and top to bottom. Customize both the tab and reading order

by using the

tabIndex property in ActionScript (in ActionScript, the tabIndex property is synonymous with the

reading order).

do not specify a tab index for all objects, a screen reader reads each object correctly.

Tab order The order in which objects receive input focus when users press the Tab key. Use ActionScript to create

the tab order, or if you have Adobe® Flash® CS3 Professional, use the Accessibility panel. The tab index that you assign

in the Accessibility panel does not necessarily control the reading order.

Reading order The order in which a screen reader reads information about the object. To create a reading order, use

ActionScript to assign a tab index to every instance. Create a tab-order index for every accessible object, not just the

focusable objects. For example, dynamic text must have tab indexes, even though a user cannot tab to dynamic text.

If you do not create a tab index for every accessible object in a given frame, Flash Player ignores all tab indexes for

that frame whenever a screen reader is present, and uses the default tab ordering instead.
