Arrange

Moving up and down in layers

Each object or group is in its own layer. The higher layer will block out view of the lower layers. The layer order is initially determined by the order in which the object is created or entered.

 

Selecting the icon on the left (highlighted on top) causes the selected object to move up one layer.

 

Selecting the icon on the right (highlighted on top) causes the selected object to move down one layer.
