[oXygen-user] Highlight matching brackets in xQuery?

I am trying out the oXygen editor, but I was surprised that bracket matching does not seem to be supported. At least it is not enabled initially. If I have for instance the following xQuery fragment: if($mall/stream[@include="subsections"]) Then, if I select the "(" then I expect the matching ")" to be highlighted. Is this supported in oXygen? If so, how do I enable it? I found no description in the manual (although maybe I missed it). Regards Hans
