Hi.

You can do something like this:

import flash.events.KeyboardEvent;
import flash.ui.Keyboard;
import flash.events.MouseEvent;
var ctrl:Boolean = false;
var mouseDown:Boolean = false;
function start():void
{
    stage.addEventListener(MouseEvent.MOUSE_DOWN, mouseHandler);
    stage.addEventListener(MouseEvent.MOUSE_UP, mouseHandler);
    stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseHandler);
    stage.addEventListener(KeyboardEvent.KEY_DOWN, keyHandler);
    stage.addEventListener(KeyboardEvent.KEY_UP, keyHandler);
}
function mouseHandler(e:MouseEvent):void
{
    if (e.type == MouseEvent.MOUSE_DOWN)
        mouseDown = true;
    else if (e.type == MouseEvent.MOUSE_UP)
        mouseDown = false;
   
    if (e.type == MouseEvent.MOUSE_MOVE)
    {
        if (ctrl && mouseDown)
            trace("ctrl + dragging");
    }
}
function keyHandler(e:KeyboardEvent):void
{
    if (e.type == KeyboardEvent.KEY_DOWN)
    {
        if (e.keyCode == Keyboard.CONTROL)
            ctrl = true;
    }
    else if (e.type == KeyboardEvent.KEY_UP)
    {
        if (e.keyCode == Keyboard.CONTROL)
            ctrl = false;
    }
}
start();

I hope it helps.

Regards,
