notification replaces sounds with visual cues or text captions to indicate that activity is happening on the
computer. As a result, system alerts are noticeable even when they are not heard. For example, when you
select one object with your keyboard, the object is highlighted. When you move the pointer to one object
with your mouse, the introductory text of the object is displayed.
To use on-screen notification, open Control Panel, click Ease of Access ➙ Ease of Access Center , and
then click Use text or visual alternatives for sounds .
