You can also choose to “Make a sound when turning a setting on or off”. If you want a warning message to display when you use the shortcut to turn on Mouse Keys, check the “Display a warning message when turning a setting on” box. If you want to turn on Mouse Keys quickly using a shortcut, check the “Turn on Mouse Keys with left ALT + left SHIFT + NUM LOCK” box. On the Set up Mouse Keys screen, check the “Turn on Mouse Keys” box to enable the feature.
NOTE: For some strange reason, if you check the Turn on Mouse Keys box on this screen and then click the Set up Mouse Keys link, you will have to turn it on again on the Set up Mouse Keys screen. However, in this case, because we’re going to show you the settings for Mouse Keys, click “Set up Mouse Keys”. If you just want to enable Mouse Keys with the default settings, you can check the “Turn on Mouse Keys” box under Control the Mouse with the Keyboard.
On the Ease of Access Center on the Control Panel window, click “Make the mouse easier to use” under Explore all settings.
