How do I rotate a jigsaw puzzle piece?

1

Hi all,
I am new to action script and haven’t been able to find any reference as to how to rotate individual jigsaw puzzle pieces using the left and right arrow keys. Can anyone help? Here is the action script that I am using:

on (press) {
startDrag("_root.pic9", true);
this.swapDepths(100);
}
on (release) {
stopDrag();
if (this._droptarget == “/target9”) {
setProperty(this, _x, 498.9);
setProperty(this, _y, 312.8);
} else {
setProperty(this, _x, 54.1);
setProperty(this, _y, 88.9);
}
}

Thanks,
Bruce
