Edit layers with active keyframes

This allows you to temporarily draw or make edits with a brush or pen on a layer (track) that has [Enable keyframes on this layer] turned on.

When on, the selected layer’s transformations will be disabled, leaving only the selected layer and paper layer. All other layers will be dis­played as semi-transparent.

It you switch to another layer, this setting will turn off automatically. All layers will return to the usual opacity.

You can also toggle this setting by clicking [Edit layers with active keyframes] on the [Timeline] palette.
