Using the timeline:
To move through the timeline, click and drag left or right depending on the desired direction. Clicking in the lower and darker grey section where dates are displayed in 10 year intervals will allow for quicker movement along the timeline.
Once the timeline has been selected by clicking on it, you can also use the keyboard to control its movement. The left and right arrow keys will move the timeline left and right respectively. The page up and page down keys will move the timeline a full screen width allowing for quicker movement than with the arrow keys. Lastly the home and end keys will move the timeline to the beginning and end of the timeline.
