Autocomplete: how to ignore metakeys and left/right arrow

Autocomplete: how to ignore metakeys and left/right arrow

I've run into some issues with the autocomplete widget triggering a search when the user hits left/right arrow or a metakey while the list is open. I found some posts from 2010 ( http://dev.jqueryui.com/ticket/5289) where this was discussed and code was seemingly added to ignore these keys, but it seems to have been removed again.

Can someone fill me in on this?

Alternatively if anyone can suggest a way I can get the widget to ignore these keys, I'd be very grateful.
