Re: Detecting keyboard usage

According to NVDA's bug tracker<http://community.nvda-project.org/ticket/57>;,
browser focus should track the virtual cursor. I think the real problem may
be that Firefox does not support the
`focusin`<https://bugzilla.mozilla.org/show_bug.cgi?id=687787> event.
Try the `focus` event instead.

Though it may not make any difference, delegate() in jquery is deprecated
as of jquery 1.7, use on() instead.
