1. Import the soundfile.
   Download keypress.mp3
   Download spacebar.mp3
   Download return.mp3
2. Give it a Linkage Identifier in the Library. (Right click on the sound in the library and select "Linkage") That's the string you will use in the typingSound.attachSound("linkage goes here"); code.
3. Place the component on the stage, give it an instance name. (myTyper is used in the code below)

Put the following code on the _root timeilne.
Be sure to replace "myTyper" with the real instancename of your WizTyper Component Instance.

CODE

//add sounds
typingSound = new Sound();
typingSound.attachSound("keypress");
spacebarSound = new Sound();
spacebarSound.attachSound("tick");
returnSound = new Sound();
returnSound.attachSound("return");
//define onTyping callback listener
_root.onTyping = function(finished, n, nTotal, curChar) {
	typing = true;
	if (curChar != " ") {
		//dont make sounds while parsing tags
		if (prevChar == "<") {
			skipMode = true;
		}
		if (prevChar == ">" && curChar != "<") {
			skipMode = false;
		}
		//make an ENTER key sound when it types a linebreak
		if (prevChar == "<" && curChar == "b") {
			returnSound.start(0, 0);
		}
		//only play while not in skipMode
		if (!skipMode) {
			//play the sound each time a letter is typed
			_root.typingSound.start(0, 0);
		}
	} else {
		//current character is a space
		spacebarSound.start(0, 0);
	}
	prevChar = curChar;
};
//add the listener
myTyper.addListener(this);
myTyper.setSentence("type this sentence with keypress sound! wooohooooo!",true);

That's all folks! Now you've got a sweet typing sound like a futuristic spaceship console.
Remember: You can use your own click sound, it will work with .wav or .mp3 files. But just make sure they're very short.
My sound keypress.mp3 is a mere 1 millisecond!
So it's very important that you make it that short if you synthesize your own click sound. Otherwise it will get all jumbled up when the component types letters.
