All Feed stories are generated from templates. You reference these templates in Feed forms, the Publisher, or the various Feed API methods (feed.publishUserAction, Facebook.showFeedDialog, and JS_API_M_FB.Connect.showFeedDialog). Templates consist of tokens, static text, and optional template data. Tokens are wild cards that get replaced inline when a Feed story is published. Two standard tokens Facebook provides are {*actor*} or {*target*}. Facebook substitutes these tokens with the relevant users' names when the story gets published. - Jordi
