In general, animations should contain multiple layers
|Rename||Double click on the name|
|Change the order||Click and drag - top layers are rendered last, on top of lower layers|
|Show/Hide||Toggle the dot below the Eyeball icon - Hiding all layers except one is an easy way to control which layer you are working on|
|Lock||Toggle the dot below the Lock icon - a locked layer can not be accidentally modified|
|Show Properties||Double click the folder in front of the name|
|Show only outlines||Click on the square box - The outline color can be changed via the properties dialog box.|
The layer with the Pen icon is currently active - all actions will modify that layer. If the layer is selected and locked, then the pen icon will have a red line through it.
