Mnemonic

With your hand, you grip a claw crane joystick and swing it wildly. The claw lurches over rows of tin cans, swaying back and forth. You swing harder—the claw finally snags a tin can and lifts it triumphantly!
Additional thoughts
Picture the arcade claw machine vividly: your hand on the stick, the metal claw swinging above shiny tin cans. The swaying motion of the claw IS the swing.
Quick recall
A hand works a claw machine, Swinging it over tin cans.
