Interactive animation using the keypress event

I am an animator and I dont know anything about flash scripting. I want to do an interactive animation using the keyboard keys but I don’t know how to program it.
It should be something like this:

on keypress A
open animationA.swf
on keypress B
open animationB.swf
–and this for all the letters.
If somebody can tell me how I should do this that would be great
Thanks
