Detecting mouse click?

[matrix5565]

I can't for my life figure it out.

The only stuff I can find online looks like:
var mouseListener:Object = new Object();
mouseListener.onMouseDown = function() {
trace('pressed');
};
mouseListener.onMouseUp = function() {
trace('released');
};
Mouse.addListener(mouseListener);

And I'm not sure how that works.
(I apologize, I'm pretty new to ActionScript)

That'll work with AS2. Just paste it on a frame in a new fla, publish and click/release the mouse to see the traces.
