How to invert modifier that comes from another node?

Dear all.
My node is like below. I have select/mask a skin tone from node 2, then i inverted it.
I don't want to select skin tone again in node 3, so i bring modifier from node 2 to node 3, but unfortunately i don't know how to do to invert it in node 3.
Thanks.

Direct option to create a following node with an inverted key is to choose Color menu > Nodes > Add Outside Node... that will automatically add a serial node, connect the mask and invert that mask for you. You can change an mask manually tho... just select the node and in the Key panel toggle the Key Input Matte/Mask button.
