Button help!

I have a lot of button symbols (468) and I am trying to get the following functionality out of them.

  1. mouseover and a number (1 - 468) increases from 7px to 12px.
  2. onPress the number stays at 12px.
  3. onPress again and the number goes back to 7px.
  4. when the user hits the “Shift” key all numbers go back to 7px.

Before my customer didnt want all of this functionality so I created all 468 as buttons and I really do not want to change them all to movie clips if I dont have to. Any help would be greatly appreciated.

Thanks!!
