You're going to have build the command first, at least unless the concat function changed.
IE you'll have to do OnHoverIn="OthURIString=' blahblahblah ' ## whatever" and then do OnPress="browser OthURIString"
I'm not sure how you'll reference the events though. I haven't really looked at that window, but you may have issues trying to get an individual event, as I recall its templated rather than dynamic-data based.
