The extra button or knob on a laptop keyboard that controls the mouse cursor is called a Point Stick. This small joystick-like device is typically located between the "G," "H," and "B" keys on the keyboard. It allows users to navigate their cursor without needing a separate mouse or touchpad, providing a unique input method for precision control while typing or while in situations where space is limited.

The design of the Point Stick enables users to move the cursor by tilting the stick in the desired direction, offering an alternative to traditional pointing devices. This feature is particularly useful for professionals who require accuracy and minimal hand movement, as it reduces the need to switch focus away from the keyboard.

While the Touchpad and Trackpad are indeed alternative input methods for cursor control found on most laptops, they are not considered extra buttons or knobs on the keyboard itself. The Scroll Wheel primarily refers to the functionality on a mouse used for scrolling and is not a part of the keyboard layout.
