What symbol indicates a change in documents?

The symbol that indicates a change in documents is the change bar. A change bar, usually represented as a vertical line or mark in the margin of a document, serves as a clear visual cue that indicates where revisions or modifications have occurred. This tool is particularly useful in documents that have undergone multiple iterations or updates, allowing readers to easily identify new information without having to read through the entire text.

Using a change bar helps in maintaining clarity and organization, especially for collaborative documents or official records that evolve over time. It enhances the reader's ability to track changes and understand the document’s progression.

The other symbols listed do not carry the same specific connotation of indicating a change. The miniature pointing hand, for instance, is often used to direct attention but does not inherently mean that there has been an alteration in the content. An exclamation mark may denote emphasis or caution, while a question mark typically indicates uncertainty or inquiry, neither of which conveys the notion of a change in text or content.
