Using sound with screen readers
Sound is the most important medium for most screen reader users. Consider how any sound in
your document will interact with the text spoken aloud by screen readers. It might be difficult for
screen reader users to hear what their screen readers are saying if your Flash application contains
loud sounds.

Viewing and creating tab order and reading order

There are two aspects to tab indexing order—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. However, if this is not the
order you want to use, you can customize both the tab and reading order using the
property in ActionScript (In ActionScript, the
reading order).
Tab order You can create a tab order that determines the order in which objects receive input
focus when users press the Tab key. You can use ActionScript to do this, or if you have Flash MX
2004 Professional, you can use the Accessibility panel to specify the tab order. Remember that the
tab index that you assign in the Accessibility panel does not necessarily control the reading order.

Professional only)" on page
Reading order
the object (known as the reading order). To create a reading order, you must use ActionScript to
assign a tab index to every instance. You must create a tab 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 produce 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. See
