keyboard and sound

[newseal]

Hello everyone
Here I would like to develop a project or find out how to do with it "as VLC player."
Its function is to be able to read files " son " or "video" just by pressing a key on the keyboard ex:
a = 1 sound file, z = 2 sound file, e = 3 sound file ,.....
have a list that carry the boot "playlist"
VLC XP launch at startup is expected that the user presses a letter on the keyboard.
is it that someone has an idea?

thank you for your help me.

merci de m'apporter votre aide.
