Help installing light switch (wires don't match)

I'm attempting to replace a light switch. As you can see from the photos, the new switch has four wires. The electrical box, though has two black wires (nutted together) and one single black wire and one copper wire. What should I match up to what on the new switch?

Sorry for the remedial question. Grateful for your help.

Switch white to the bundle of whites connected together.
Switch black to the two blacks connected together.
Switch red to single black wire.
All grounds connected together.
