On most computers, the user can move the mouse to move the cursor in the same direction.[3] To choose something that is on the screen, the user can move the cursor to it and "click" the left mouse button. The right mouse button is used to open menus that are different depending on where the cursor is. The other mouse buttons can do different things, depending on the software. Most mice have two buttons to click.
Most mice also have a "scroll wheel"—a small wheel found between the two main mouse buttons. The user can move the wheel back and forth to "scroll" through things like a website or folder. "Scrolling" means moving the words or pictures up or down on the screen, so another part of the page comes into view. The wheel can also be pressed, to click it like another button.
