   3575          *   Note: These key bindings are for the built-in accessibility navigation for
   3576          *   web content which is used as a fall back solution if JavaScript in a WebView
   3577          *   is not enabled or the user has not opted-in script injection from Google.

   3579          * <p>
   3580          *   The bindings are separated by semi-colon. A binding is a mapping from
   3581          *   a key to a sequence of actions (for more details look at
   3582          *   android.webkit.AccessibilityInjector). A key is represented as the hexademical
   3583          *   string representation of an integer obtained from a meta state (optional) shifted
   3584          *   sixteen times left and bitwise ored with a key code. An action is represented
   3585          *   as a hexademical string representation of an integer where the first two digits
   3586          *   are navigation action index, the second, the third, and the fourth digit pairs
   3587          *   represent the action arguments. The separate actions in a binding are colon
   3588          *   separated. The key and the action sequence it maps to are separated by equals.

   3590          * <p>
   3591          *   For example, the binding below maps the DPAD right button to traverse the
   3592          *   current navigation axis once without firing an accessibility event and to
   3593          *   perform the same traversal again but to fire an event:
   3594          *   <code>
   3595          *     0x16=0x01000100:0x01000101;
   3596          *   </code>
   3597          * </p>
   3598          * <p>
   3599          *   The goal of this binding is to enable dynamic rebinding of keys to
   3600          *   navigation actions for web content without requiring a framework change.
