Below, you will find a few examples of how application interoperability with accessibility features should work. Proper compliance with this requirement will help guarantee that users of AT will be able to interact with the product successfully.

Users with limited mobility may use an onscreen keyboard to help them navigate a computer system. In the first image below the First Name form field is highlighted with an onscreen keyboard available. When a user activates the Tab key on the onscreen keyboard, the action is transmitted to the operating system and the action is performed. The second image shows the Tab key being activated and how focus in the application is moved to the Last Name field.

Users may activate Sticky Keys. The Sticky Keys feature enables users to control the speed at which they press keys that typically are pressed at the same time to fire an action within an application. The example below demonstrates the combination of Alt and Tab being pressed simultaneously to activate the task switching function of the operating system.

The next graphic demonstrates that once the Sticky Keys feature is turned on, each key can be pressed separately to achieve the same result as simultaneous key presses.
