What is the Cinemachine yellow dot, ("look ahead" dot), and how to access its values?

What is the yellow dot in the center of the screen called?
Is it called “look ahead” something?

I want to accesses the values of this through script, so that I can set pan and tilt on the camera.

You can do vcam.GetCinemachineComponent<CinemachineFramingTransposer>().m_LookaheadTime = bla
and similar for m_LookaheadSmoothing and m_LookaheadIgnoreY
