%1 in events

How exactly do you make it work.
It works fine in the server greeting but how do you make it work in events. Just %1 or is there some notation thing like " . %1 . "

%1 only works in chat message

Not only that, but I think it only works on Minigames.

I only wanted it to work in minigames but I never knew it was only in chat. Thanks. And trying to search
%1 on BL forums just comes up with searching 1.
