When comparing two resources, which tool can be used to navigate through changes?

The use of scroll bars as a tool for navigating through changes when comparing two resources is effective because they provide a straightforward way to move through large sets of data or changes. When comparing data side by side, especially in scenarios where numerous entries are present, scroll bars allow users to easily view and access different sections of the content without needing to zoom in or out or switch between different panes.

Scroll bars are universally recognized and offer a clear mechanism for users to adjust their viewing area dynamically, making it easier to analyze discrepancies or modifications line by line. They also facilitate the review process by allowing users to quickly jump to specific areas of interest in the data, enhancing the overall efficiency of comparisons.

Other tools mentioned, such as color indicators and visual indicators, may highlight changes effectively but do not provide the same level of navigation capability as scroll bars. Line numbers may help identify specific entries but do not aid in physically navigating through the dataset in a fluid manner. Thus, scroll bars are a critical tool for users to easily and efficiently browse through content changes during comparisons.
