Enable animated layer order in AS pro 10

[Equalrights4animals]

I just don't know where the "enable animated layer order" button is. Where is it?

[Víctor Paredes]

In the bone or group layer proprieties, in Depth sort tab. Animated layer applies to the layers inside that group or one layer.

What about for layers that aren't in a bone or group layer?

If layers aren't inside a group/bone, you simply can't animate their order. The simplest way is to create an overall group and put all your layers inside it.
