You can use the levers on each of the foot pedals to activate autopilot modes.
To turn Heading Hold on or off,
push the lever on the left pedal.
To turn Anchor Lock on or off,
push the lever on the right pedal.
NOTE:By default, the right foot pedal lever activates Anchor Lock regardless
of your Anchor Mode setting. You can configure the foot pedal levers to
activate other functions, including Bow Lock (Changing the Function of the Foot Pedal Levers).
