Mouse
Mouse Keys is designed to help people who can’t use the mouse—or who
want more precision when working in graphics programs. It lets you click,
drag, and otherwise manipulate the cursor by pressing the keys on your
numeric keypad. (It’s not very useful on keyboards that don’t have separate
numeric keypads, like laptops.)
When Mouse Keys is turned on, the 5 key triggers a click, and the + key
acts as a double-click. (Specify a left-button click by first pressing the / key,
or a right-click by pressing the - key.)
Move the cursor around the screen by pressing the eight keys that surround
the 5 key. (For example, hold down the 9 key to move the cursor diagonally
up and to the right.) You can even drag something on the screen; press 0 to
“hold down the button” on something, and then move it using the number
keys, and press the period (.) to let go.
The sliders here govern the overall acceleration and speed of the cursor
movements, although you can always speed up by pressing Ctrl and slow
down by pressing Shift (if you’ve turned this option on here).
Tip
It’s kind of clunky to have to burrow all the way into PC Settings every time you want to turn on
Mouse Keys. Fortunately, there’s a shortcut: the Num Lock key on your keyboard. It turns on
Mouse Keys (at least if “Only use Mouse Keys when Num Lock is on” is on).
Eye Control
Whoa, cool! If you’ve bought a Tobii eye-tracking camera, you can now
control the motion of your cursor just by looking at the screen. Windows
translates your gaze into mouse movements—very convenient if you’re
unable to use your hands. Here’s where you set up and configure your eye-
tracking hardware.
Once everything is running, you get special onscreen floating palettes with
buttons for “left click,” “right click,” “double-click,” and so on. You can
