Free Move and Free Resize
Demo Builder allows you to move or resize the cursor motion only if the cursor is always synchronized with the movie. For example, if a scene has two "changes" and you have a cursor motion in the first "change", you'll notice that you cannot move the cursor motion to overlap the start of the second "change". To "free move", simply hold down the CTRL key and drag the cursor motion. To "free resize", hold down the CTRL key and drag the small arrow cursor in the Timeline.
