KeyPress question

hello,

I am completely stuck, as a newby to actionscript, yet trying to undertake in my eyes an impossible task, maybe you can help!

what i want to do is this. I have designed an animated alphabet- now i want to attatch then to keys of the keyboard so when you press the letter then on the screen it pops up. Then if left idle for 15 seconds fades out to the blank screen again. So i have all these individual animated letters as movie clips, i just need to know how to script the whole thing together!

if anyone has any info or can reffer me to a good tutorial i would be forever grateful!

thanks.
