Animating a simple line or box on the screen.

Hi all,

Animating a simple line or box.

I have seen this on various tech videos and I am curious how to do it:

Currently, I can create a simple line or box using the annotations tool and format it how I like. Next I would like to be able to animate that same line / box and have it move to a different position on the screen and possibly be a different size and format.

Can someone let me know how to do this?

Thanks– Dave
