+        [iOS] Hardware Keyboard: All combinations of arrow keys and space key do not scroll the view.

+        rdar://problem/18466015
+
+        We don't normally get called by the keyboard to handle the event if we are not
+        interacting with editable content. In order to receive all the hardware keyboard events
+        we need to implement _handleKeyUIEvent which is called for every key event
+        when the view is first responder. This gives us the opportunity to send each keystroke
+        to the WebProcess to let any Javascript handler intercept it and then perform the default
+        action for the key combination.
+        Unfortunately this mechanism does not provide key repeat, which is implemented in the
+        keyboard layer. In order to have it at least for the arrow keys, we use the keyCommands
+        mechanism only for those.
