Step 9. Set the speed at which the pointer moves
If you do not change the speed and acceleration of the pointer, it will move very slowly. That's why:

If the cursor does not move, press Num ⇩ and try again

Step 12. Move the pointer using the numeric keypad keys
Press 4 to move the cursor to the left; 8 to move the cursor up; 6 to move the cursor to the right; 2 to move the cursor down.
