·Select Edit|Add shape and click the area of the map to add a first node of the shape (what kind of shape is created depends on the type of the layer - polygon, line, or point).  
·(now you are automatically switched to "Edit|Vertex edit" mode which allows you to edit nodes).  
·you can continue adding nodes to create the kind of shape you want.  
·to change the position of the node simply click and drag it to new position.

To enable snapping of the nodes (moved or inserted) to the nodes of the shapes in the same or different layers select Edit|snap|Snap layer.
This would mean that when the node is moved or inserted it automatically "snaps" to the closest node of the "snap layer" within "snap margin".
Edit|Save commands allow you to either save/revert individual layers or all layers that have been edited.
To stop editing click the "Edit|Enable editor" button again.
