Which button is indicated by the marking "FOR" in the displayed diagram?

The marking "FOR" in the displayed diagram typically signifies a function related to direction or operation, particularly in a context involving movement or progression. In many systems, especially those involving motors or transport mechanisms, "FOR" is shorthand for "FORWARD." This indicates that the corresponding button or control will activate the component to move or operate in a forward direction, aligning with the common interpretation of the abbreviation.

Understanding this marking helps users identify the purpose of the control easily, as it suggests that pressing the button will result in forward motion or progression in whatever system is being operated. This context is vital for safety and operational effectiveness, as it clearly differentiates between forward operations and other functions like stopping or reversing.
