Editing button frames

[soc86]

I have created a symbol to type button in flash and would like to enter a
motion tween with a few more frames, onto my key frame called over.
I would like the user to hover over my button, when he/she does this the
button will gradually change size.
Is there any way to edit the key frame called over to do this??

Inserting a movieclip that has that gradual enlargement is the only way to change it in the over frame itself.

I tried inserting a movie symbol into the "over" frame and i dont' know what
happens to it when I click into scene1 again...where did it go? Can you
provide more detailed steps as to how to accomplish this? This is exactly what
I've been trying to find out. Thank you.
