nsMenuBarListener::KeyPress() is eKeyEvent listener in the system event group. If the target is a remote process, it shouldn't handle accesskey immediately because preceding eKeyDown event may be consumed in the remote process or eKeyPress event itself may be consumed in the remote process. This patch makes nsMenuBarListener::KeyPress() mark eKeyPress event as "waiting reply from remote process" only when the event matches with a menu item's accesskey and it will be send to a remote process later. Then, reply event should be handled in this method if it's available. MozReview-Commit-ID: KOpCVgElnca --HG-- extra : rebase_source : 881ec01f5c8e21c790bf9a8c3167d6c3f932524a
