This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the

KeyboardEvent.initKeyboardEvent()
method initializes the attributes of a keyboard event object. This method was introduced in draft of DOM Level 3 Events, but deprecated in newer draft. Gecko won't support this feature since implementing this method as experimental broke existing web apps (see
bug 999645
). Web applications should use constructor instead of this if it's available.
