Windows 8/8.1 – Using your keyboard to control the mouse:
Most people think that a computer has to be operated only with the mouse and that, if you cannot use a mouse, you cannot use your computer. This is not the case. In fact your computer not only be operated entirely from the keyboard, but doing so can often faster and easier than using the mouse.
Method 1: Using the ‘Ease of Access Center’ in the Control Panel
This method has more configuration options than Method 2, but it is recommended for users with a keyboard and/or a mouse – the interactive elements are small and therefore difficult to tap. If you are using a tablet or a phone, you will probably prefer Method 2.
To open the ‘Ease of Access Center’ in the Control Panel
From a computer with a keyboard and a mouse
  • Press the ‘Windows’ key + U.
Or
  • Move the mouse pointer to the upper right hand corner of the screen to reveal the charms.
  • Click on the ‘Search’ charm – the one with the magnification glass icon.
  • Type the query ‘Ease of Access Center’ in the search box (Fig 1).
  • Click on the button ‘Ease of Access Center’.
From a touch enabled device
  • Swipe in from the right hand edge of the screen to reveal the charms.
  • Tap on the ‘Search’ charm – the one with the magnification glass icon.

  • You can turn on the keyboard shortcut Alt + left Shift + Num Lock to allow you to turn on and off the Mouse keys as you need to use them. To use this option, select the checkbox (Fig 4). You can turn on a visual warning ‘Alt’ + ‘A’ when Mouse keys is turn on or click to play a sound ‘Alt’ + ‘U’ when it is turned on or off.

Figure 4
Pointer speed when using Mouse Keys can be tailored to suit your needs by slowing down or speeding up the rate which it moves (Fig 5). Press ‘Alt’ + ‘W’ or click to select the option to alter these settings, by using the Ctrl key to speed up and Shift to slow down the mouse pointer. Top Speed is the maximum speed of the pointer when the mouse key direction key is held down. Acceleration is how quickly the mouse pointer accelerates to its maximum speed.

 
Figure 5
  • Under ‘Other Settings’, click to select to Use Mouse Keys when the Num Lock is selected or when NUM LOCK is ‘Off’ (Fig 6). Press ‘Alt’ + ‘N’ to Use Mouse Keys when NUM LOCK is ‘On’. To select Use Mouse Keys when NUM LOCK is Off, ‘Tab’ to ‘On’ and press the down arrow or click to select.
