What is used in ladder diagrams with multiple pages to indicate previous and next pages?

In ladder diagrams that span multiple pages, arrows are commonly used to indicate the navigation between different pages. This practice helps to visually guide the reader or technician from one section of the diagram to another, illustrating the flow of the electrical control system across multiple layouts. Arrows effectively indicate where to look for the continuation of the circuit, enhancing clarity and accessibility, particularly in complex systems that require referencing various pages to understand the entire setup. This visual cue ensures that anyone using the ladder diagram can easily follow the flow of control logic without confusion.

While other options might provide various forms of information or organization, arrows specifically fulfill the purpose of indicating both previous and next pages efficiently, making them the most suitable choice for this application in ladder diagrams.
