Facebook text field detection

i just want to 开发者_如何转开发ask if there is an api for facebook to detect any text field, be it status update text field or comment text field or any other.

So you are asking for your application to get notified when a user does an activity on Facebook (outside your App) like writing a status message or a comment AND even more, when he focuses on those fields!

Well, for the later that's absolutely not possible yet you can still receive some "updates" when a user does certain activities by subscribing to the Real-time methods Facebook provides.
