In computing, a pointer or mouse cursor (as part of a personal computer WIMP style of interaction) is a graphical image on the computer monitor or other display device. The pointer echoes movements of the pointing device, commonly a mouse or touchpad. It can be used to select and move other graphical user interface elements, and is distinct from the cursor, which responds to keyboard input. The cursor may also be repositioned using the pointer.
