Outstanding find and tip so, thanks very much.
I have seen many comments at various sites that rave about this change to Safari to integrate search and Location Bar with many of them belittling users who don't see it as a step forward in browser development. Perhaps it was a result of significant numbers of people making their opinion heard at Apple that prompted the change.
I have been very disappointed with this particular change in Safari 6, especially because Apple has provided zero options to customize that aspect of the toolbar/location bar.
