Movement with actionscript

1

I have a floating menu on my page that the viewer can drag around the screen. I need to have the viewer be able to click on it and it move to a certain spot on the screen from where it was. I can make it go to a certain point by setting the _x and _y values of it, but I want to be able to see the motion of it going to that point, instead of just appearing there. Hope I explained clearly. Thanks.
