Checkpoint 1.10 - Flash

Flash automatically enables all controls to be accessible by the keyboard however it is still important to ensure that all buttons can be activated via a keyboard since some techniques used by Flash developers might prevent buttons from being accessed by a screen reader or a keyboard.

Requirement

Ensure all buttons and controls can be activated by a key stroke.

Recommendation

Avoid empty hit areas by placing a transparent movie clip into the active state of the button. The screen reader will recognise it as a button and will allow the user to select it. If this is not done, the button will be ignored.

Checking Tool

Tab through the Flash content and ensure all buttons can be easily activated by the keyboard.
