  To move a frame on the timeline, simply click on it and drag it to the time you want it to start. The start time will be displayed as you drag. How frames move relative to each other is determined by whether the timeline is locked (see previous section). To resize a frame grab the right-hand edge and drag it. When moving or resizing the mouse snaps to the nearest unit on the timeline. If you hold SHIFT while moving or resizing no snap will be applied. When the timeline is unlocked then if you hold CTRL while dragging or resizing a frame all frames to
  the right of the selected frame will be moved so that the time interval between the selected frame and the next one is maintained.
