What feature in a word processing program moves the insertion point to the next line automatically?

The correct answer is word wrap. This feature in a word processing program allows text to automatically move to the next line when the current line reaches the end of the page or the designated margin. As you continue typing, the text adjusts itself to fit within the defined space without requiring the user to press the Enter key manually. This functionality is crucial for maintaining a clean and organized layout, allowing for continuous flow in writing without interruption.

While line spacing refers to the distance between lines of text, it does not inherently manage how text moves from one line to the next. Text wrapping can sometimes be used more generically to describe how text adjusts around images or other elements, but in the context of moving the insertion point to the next line, word wrap is the more precise term. A page break is a specific command that forces the text to the next page entirely, which is not what happens when simply reaching the end of a line. Therefore, word wrap clearly best fits the function described in the question.
