I am fairly certain that this appeared after I replaced my iPad (piece of dust under the screen) and restored a backup of my old one. It appears next to the cut/copy/paste dialog when text has been highlighted. I mean the fourth icon on the end, the little globe. When I tap it an alert pops up with only the text that's been highlighted. I don't understand what it's supposed to do or how it got enabled, so it's confusing me. Any idea as to the purpose and/or how to turn it off?
