The Highlighter is an essential feature of the Snipping Tool, designed to emphasize and draw attention to specific parts of a captured snip. Once you capture a screenshot, the Highlighter allows you to mark important sections with a translucent color, making them stand out from the rest of the content. This is particularly useful for emphasizing key points in documents, highlighting errors or corrections, and drawing attention to critical information in instructional materials or presentations. The Highlighter is customizable, offering a range of colors and thicknesses to suit different needs and preferences. Whether you need to underscore a single word or highlight an entire paragraph, the Highlighter provides a clear and visually appealing way to enhance your snips, ensuring your audience quickly notices and understands essential information.
