An access key is an underlined letter in a control of an application. It allows the user to select an object using the Alt key in combination with a letter or number. Access keys are not case sensitive. In an interface, you should assign access keys to each control that can accept user input, such as text boxes and buttons. Access keys are important because they allow people with certain physical disabilities to interact with the application's interface.
