I often have Safari open while working on a project in Xcode, looking up stuff on Stack Overflow and the like. A few times, I've searched something in to the web address/search engine field of Safari, and a word or two from what I typed in and it will be entered into the Search Navigator in Xcode, even though I didn't type it in there. It doesn't do it every time.
EDIT: Text entered in through the Search Navigator can pop up in Safari too.
This doesn't cause any problems, but the words it picks don't seem to have any relevance, and I'm curious as to why this oddity is happening.
I'm running Xcode 4.6.3, Safari 6.0.3, and Mac OS X 10.8.4
Is this a glitch? A half-baked feature?
