What does creating a highlight in a document do?

Creating a highlight in a document serves as a visual cue to emphasize specific portions of text. When you highlight text, it creates a colored box overlay on the selected area, allowing the highlighted content to stand out for easy reference. This feature is particularly useful for reviewing important points or taking notes, as it draws attention to the selected segments without altering the underlying text.

The other options involve different actions that do not align with the highlighting functionality. For instance, removing text and converting the document to a different format are actions that fundamentally change the content or structure of the document rather than emphasizing it. Similarly, adding a comment involves attaching a separate note or feedback without visually marking the text itself. Highlighting is specifically intended for visual emphasis, making it a distinct and valuable tool in document editing and reviewing processes.
