Paste into twitter app Galaxy Chat

Am trying to figure out how to paste in the twitter app. Any other place I just need to touch the screen, hold down and the paste icon appears. But in the twitter message box it just doesn’t appear! Have know idea how to do it. There should be some shortkey…. since it’s a qwerty smartphone after all. Hope to update soon.

UPDATE:It suddenly started to work. There’s no reason, there’s no rhyme 🙂
