The scroll wheel is like a small wheel located between the left and right buttons on your computer mouse. It’s similar to the wheel on a shopping cart. When you roll it away from you (upward), it’s like flipping the pages of a book forward. When you roll it toward you (downward), it’s like turning the pages backward.

Using the scroll wheel helps you move up and down on a webpage or document without clicking on the scroll bar. It’s a convenient way to navigate through content, especially when reading articles or browsing websites. Simply roll the wheel with your finger to move through the information on your computer screen.
