Make a button at frame 1, and place it on stage. This button should launch
the typewriter,
so it has to have a little piece of code attached to itself (rightclick the
button, and chose actions).
o the button has these actions:
on (releasee) {
play();
}
Thats it, three easy steps.
If you are wondering about any of the commands used, they are all very good
explained in the actionscript dictionary.
To open up the dictionary, press F1 while inside flash :o)
