Cut, Copy, Paste Layers
The options Cut, Copy and Paste, common to many softwares, can be applied to Animation Layers.
They also allow to remove, duplicate, move or flip the layers, and they are accessible with the usual shortcuts [Ctrl + C], [Ctrl + X] and [Ctrl + V].
These options are also available in the Layers main menu or the contextual menu.
It is also possible to Cut, Copy and Paste some Animation Layers from one project to another.
Before transferring them from one Project to another, always ensure the resolution is correct, otherwise your images may be distorted.
