I'm wiring my basement and have two three-way switches in a two gang box. The left switch (S1) and another 3-way control four recessed lights. I want the switch on the right of the box (S2) to control another set of recessed lights.

I want to power S2 using jumpers from S1. Is this possible? If so how. The wiring book I have only discusses using jumpers with single pole switches.

Thanks

If there is a constant hot and a neutral, you can, look through the links for different 3 way switching:
