Development and Remediation Guidelines

As §1194.21(a) specifies, software should be designed so that it is fully functional while using the keyboard. Mouse support should be considered optional, instead of the other way around, since users with motor or visual disabilities may not use a mouse.

The Windows Operating System provides provision keyboard equivalents for general interface behavior, such as navigating among controls and windows, activating controls, adjusting window and region sizes, and scrolling controls and windows. Software should be designed so it does not override this built-in behavior.
