How can I use a keyboard to control the mouse in win7?

1. First:

 

2. Mouse keys corresponding to the keypad:

Move: Keys 8, 2, 4, 6, 7, 9, 1, and 3, eight orientations

Long-distance movement: Ctrl + more than eight keys (I .e., accelerated movement)

Select the left mouse button :/

Right-click and choose :-

Click: 5

Double-click: + (or double-click "5 ")

Drag: 0 (INS)

Release:. (DEL)

Click the left mouse button to press (/) and then (5) or directly Press (5); double-click to double-click (5) or press (+); Right-click to press (-) then press (5). to switch back to the left-click mode, press (/). You can also press the right-click button on the big keyboard to right-click (next to the right-click Key ); drag the window to move to the title bar of the window, press ins, and then use the "move" Key (Keys 8, 2, 4, 6, 7, 9, 1, and 3) move the window to a proper position and then press del to release the window. The method for dragging a file or folder is similar.
