A multidimensional mouse of computers includes a Z-axis key pivotally connected to the mouse by a pivot and defines two ends spaced from each other by the pivot. Two elastic loads respectively installed inside the mouse and a corresponding one of the two elastic loads is deformed in response to a manual depression on one of the two ends of the Z-axis key, thus allowing an electrical contact to occur inside the mouse, and this electrical contact is retained if the manual depression is retained. The deformed elastic load has a tension to recover the Z-axis key back to a non-depressed position after the manual depression on the Z-axis key is released. A displacement of a cursor along a Z-axis on a computer screen is based on a time period during which the end of the Z-axis key is kept depressed.
