Success Criterion 2.1.3 Keyboard (No Exception) Understanding Keyboard (No Exception) | How to Meet Keyboard (No Exception) (Level AAA) All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes. Success Criterion 2.1.4 Character Key Shortcuts Understanding Character Key Shortcuts | How to Meet Character Key Shortcuts (Level A) If a keyboard shortcut is implemented in content using only letter (including upper- and lower-case letters), punctuation, number, or symbol characters, then at least one of the following is true: Turn off A mechanism is available to turn the shortcut off; Remap A mechanism is available to remap the shortcut to include one or more non-printable keyboard keys (e.g., Ctrl, Alt); Active only on focus The keyboard shortcut for a user interface component is only active when that component has focus. Guideline 2.2 Enough Time Understanding Enough Time | How to Meet Enough Time Provide users enough time to read and use content. Success Criterion 2.2.1 Timing Adjustable Understanding Timing Adjustable | How to Meet Timing Adjustable (Level A) For each time limit that is set by the content, at least one of the following is true: 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. Note This success criterion helps ensure that users can complete tasks without unexpected
      changes in content or context that are a result of a time limit.
