Nicky may have a shorter way, but this is how I'm guessing you do it for text. If you're going to paste the text in, first duplicate it by the amout of frames there are in the animation and then just click CTRL + A and it'll highlight evey frame for the text. Then click CTRL + A on the animation one and it'll highlight every frame and drag the text onto the animation and it'll go onto every frame.

That's how I used to do it for heart animations and stuff on banners but I'm not sure if its used for text.
