How the WIN8 system uses the numeric keypad instead of the mouse
First, on the WIN8 system desktop, right click on the Win button, and then select "Control Panel." Then, on the Win8 System Control Panel, click on the "Easy to use" menu.
Second, in the WIN8 system easy to use the menu panel, click the "Change the way the keyboard Works" button.
Third, then enter the "make keyboard easier to use window", tick "Start mouse button", and in the following window, click the "Apply" button.
After enabling the mouse button on the WIN8 system, and then using the numeric keypad to simulate the mouse, and then control the speed through the CTRL key and the SHIFT key, you can also set it further by "Enable MouseKeys" and "set MouseKeys".
The above is the WIN8 system uses the numeric keypad to replace the mouse operation method, as long as the control Panel in the "Make keyboard easier to use window" page of the start of the mouse button can be implemented with the numeric keypad to replace the mouse.
