Sliding menu speed

Can anyone point out where a control for the speed either is or can be inserted for the sliding menu. Cudos to the original developer of this menu. I adapted it to fit our needs:

Here is the current code for the entry piece:

// This sets the position of the clip when you start
onClipEvent (load) {
	_root.xnew = _root.mask2._x+(-6.25-1)*100/2;
}
// Pretty much obvious. The destination is controlled by the small clip. That little
// clip is made out of invisible buttons that give a destination interpreted by the
// function move ()
onClipEvent (enterFrame) {
	move();
}

TIA!
