Slowing down a animation?

hey all,
i am new to flash. i had a small banner animation made out. now its done and i see that the text come and goes too quickly. i want the text to slow down so its readable or stay for few second before moving on. how can i do that?

Add more frames to the timeline so there’s more time between the tweens.

add where? there are 3 key frames now. start, middle(diamond shaped) and end
