Invert Color Range Key

[jimlolo]

How do I reverse it so the transparent area within the keyed area is swapped with the area outside the key thus making the area inside visible and the outside area transparent? I see no inverse option.

Thanks.

Pre-compose, apply an Invert effect, select the Alpha channel.

How do I apply an Invert Effect on the pre-composed layer?

Select the layer, apply Effects>Channel>Invert.

No need to pre-compose unless you want to - just put it below the Color Range Effect.

Ah, under Channel. Thanks.
