Moving the camera view when the mouse button down is detected. HELP!

programming flash
1

I am quite new to actionscript 3.0 but i’m sure this should be so simple.

The objective is to get the camera view to move when the mouse button is down.

Here I have managed to get the camera view to move forward using the UP arrow key:

cameraView.velocity = 0;
var fmovement = 0;
	
	if (Key.isDown(Key.UP)) {fmovement += 10; cameraView.velocity += 2;}
	else cameraView.velocity *= .95;

How can I change this to when the mouse click is down??? thanks in advance.
