The button will add the official Topic name in blue. So, if you press , and start typing ‘ABC ga’ it should then give you an auto-suggest list where you can pick which you mean, and will then display it like this:
ABC game Where in the World (part 2)
These ones have no post id in, so are great for directing people to the top of a Topic (eg. one where the info is all at the beginning).
