What does keyboard accessibility mean?

To be keyboard accessible a web page must not only be keyboard operable it must also incorporate the following: a visible keyboard focus, appropriate tab order, and avoid keyboard traps.

Why do we test for keyboard accessibility?

Keyboard accessibility is one of the most important aspects of web accessibility. Many users with motor disabilities rely on a keyboard. Some people have tremors which don't allow for fine muscle control. Others have little or no use of their hands, or no hands at all.

How do you make a keyboard element accessible?

An element is clickable if it has an onclick event handler defined. You can make it focusable by adding a tabindex=0 attribute value to it. You can make it operable with the keyboard by defining an onkeydown event handler; in most cases, the action taken by event handler should be the same for both types of events.
