From UAAG specification, checkpoint 11.4: 1. Allow the user to override any binding in the user agent default keyboard configuration with a binding to either a key plus modifier keys or to a single key. 2. For each functionality in the set required by checkpoint 11.5, allow the user to configure a single-key binding. A single-key binding is one where a single key press performs the task, with zero modifier keys. See the UAAG tests listed below: UAAG Checkpoint 11.4: Single-key access - Test 225: Control Animated Images Using Single Keys test URL: http://cita.rehab.uiuc.edu/wai-eval/show-test/index.php?test_id=225
