Drag & Drop Frame The sequence of the frame in the animation can be changed by Draging & Droping.Firstly,you must click on the frame with mouse left button which you want to drag .Secondly, you may move mouse to new point that indicates the new position frame will be inserted without releasing the mouse button.In the process, a half transparent image which presents the draged frame is moved along with the mouse.A red mark occurs in the middle of two connected frames,which means that the new position the draged frame will be inserted.If you release up the mouse button,the draged frame is removed from old position,and inserted at the new position.
