On Windows, Mac and other graphics-based screens, it is also called a "pointer," and it changes shape as it is moved with the mouse into different areas of the application. For example, it may turn into an I-beam for editing text, an arrow for selecting menus or a pen for drawing.

On DOS and Unix command lines as well as other character-based screens, the cursor may be a rectangle, an underline or a vertical line, and it is typically blinking. See database cursor.
