+For accessing the timeline view, you have to click on the button with the clock
+icon in the view switcher. The first time you access to it, the timeline window
+is zoomed to fit all the current elements, the same as when you perform a
+search, filter or group by operation.
+
+You can use the mouse scroll to zoom in or out in the timeline, and click on
+any free area and drag for panning the view in that direction.
+
+The records of your model will be shown as rectangles whose widths are the
+duration of the event according our definition. You can select them clicking
+on this rectangle. You can also use Ctrl or Shift keys for adding discrete
+or range selections. Selected records are hightlighted with a different color
+(but the difference will be more noticeable depending on the background color).
+Once selected, you can drag and move the selected records across the timeline.
+
+When a record is selected, a red cross button appears on the upper left corner
+that allows to remove that record. This doesn't work for multiple records
+although they were selected.
+
+Records are grouped in different blocks depending on the group by criteria
+selected (if none is specified, then the default group by is applied).
+Dragging a record from one block to another change the corresponding field to
+the value that represents the block. You can also click on the group name to
+edit the involved record directly.
+
+Double-click on the record to edit it. Double-click in open area to create a
+new record with the group and start date linked to the area you clicked in.
+By holding the Ctrl key and dragging left to right, you can create a new record
+with the dragged start and end date.
