WINDOWS KEYBOARD EMULATOR FOR MAC MAC OS
Mouse Keys (a Windows and Mac OS feature that enables control of the mouse pointer by keyboard) is not a keyboard emulator. While keyboard emulators (such as on-screen keyboards, alternate keyboards, speech input, etc.) may be utilized, testing instructions may differ. This test was written to be performed on a standard physical keyboard for a Windows PC.Keyboard access and control includes the ability to navigate to AND away from interactive content using only a keyboard. If an interface uses non-standard keyboard commands, the interface must clearly document the commands and make users aware that the commands exist. This requirement relies on use of a keyboard to validate access and control of all functionality of the content first by checking use of standard keyboard commands (TAB, Space Bar, Enter, Escape, etc.). Conformance Requirement 5: Non-Interference - The following success criteria apply to all content on the page, including content that is not otherwise relied upon to meet conformance, because failure to meet them could interfere with any use of the page: 1.4.2 - Audio Control, 2.1.2 - No Keyboard Trap, 2.3.1 - Three Flashes or Below Threshold, and 2.2.2 - Pause, Stop, Hide.WCAG SC 2.1.2 No Keyboard Trap – If keyboard focus can be moved to a component of the page using a keyboard interface, then focus can be moved away from that component using only a keyboard interface, and, if it requires more than unmodified arrow or tab keys or other standard exit methods, the user is advised of the method for moving focus away.WCAG SC 2.1.1 Keyboard – All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes, except where the underlying function requires input that depends on the path of the user’s movement and not just the endpoints.
