  **Sequences**
--
  The sequencer allows you to make your robot move over time by transitioning from one position to another. Each transition we call a frame and a sequence of frames we call a sequence. You can create as many sequences as you like. You can play sequences back manually or using the keyboard inputs mentioned below. This section describes the sequence management functions of the Sequencer.

  **Timeline Locking**

  The timeline is locked by default. This means that frames will automatically run from one to the next – you cannot create space in between. Moving a frame past another one will move it along the order in the timeline. If the timeline is unlocked then you can move frames independently of each other and also create gaps of time in between.

  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.
