Highlighters are special pens filled with bright, translucent ink that people use to mark important information in books, notes, or documents. They come in various colors, like yellow, pink, and green, making it easy to organize and categorize information. Students and professionals often use highlighters to emphasize key points, making studying or reviewing material more efficient. Using a highlighter can help improve memory and focus. When you highlight text, it draws your attention to the most important ideas, making it easier to recall them later. Many people find that using highlighters alongside other tools, like sticky notes or notebooks, enhances their learning experience.
