In the Behaviors tab of the Inspector, click the Animation menu next to the Scale Y 
parameter, then choose Add Keyframe.
A black diamond appears on the Animation menu to indicate that the parameter is 
now keyframed and that the current frame contains a keyframe. 
Due to the way keyframing works, adding a single keyframe does not change the effect 
at all. It takes at least two keyframes to create a change over time.

Press Page Down to move the playhead forward one frame.

Click the Animation menu, then choose Add Keyframe again.

Use the value slider to set the Y value to 150 percent.
This creates a second keyframe with a different value than the first. Now, the sequence 
shrinks the letters to 25 percent from the beginning until the first keyframe, and then 
stretches the letters to 150 percent from the second keyframe until the end of the 
effect.
