Action-162 A.3.2.2 and rationale

A.3.2 Provide authors with enough time

Rationale: Some authors who have difficulty typing, operating
     the mouse, or processing information can be prevented from using
     systems with short time limits or requiring a fast reaction speed,
     such as clicking on a moving target.


adapted from WCAG 2.2.1
A.3.2.2 Timing Adjustable: For each time limit that is set by the 
authoring tool, at least one of the following is true: (Level A)

     * Turn off: The user is allowed to turn off the time limit before 
encountering it; or
     * Adjust: The user is allowed to adjust the time limit before 
encountering it over a wide range that is at least ten times the length 
of the default setting; or
     * Extend: The user is warned before time expires and given at least 
20 seconds to extend the time limit with a simple action (for example, 
"press the space bar"), and the user is allowed to extend the time limit 
at least ten times; or
     * Real-time Exception: The time limit is a required part of a 
real-time event (for example, an auction), and no alternative to the 
time limit is possible; or
     * Essential Exception: The time limit is essential and extending it 
would invalidate the activity; or
     * 20 Hour Exception: The time limit is longer than 20 hours.
