The purpose of this note is to describe a framework which unifies radial, chordal and dipolar SLE. When the definition of SLE(κ;ρ) is extended to the setting where the force points can be in the interior of the domain, radial SLE(κ) becomes chordal SLE(κ;ρ), with ρ=κ-6, and vice versa. We also write down the martingales describing the Radon-Nykodim derivative of SLE(κ;ρ₁,...,ρ_n) with respect to SLE(κ).
