Configuring and Using Mouse Assistance

Mouse Keys enables users to control the location of the pointer by using the numeric keys on the keypad; this can be useful if a person has difficulty manipulating a mouse or trackpad. To configure Mouse Keys, perform the following steps:

1.	Open the Mouse (or Mouse & Trackpad on a mobile Mac) tab of the Universal Access pane of the System Preferences application.
2.	Click the On radio button to turn Mouse Keys on.
3.	You can enable Mouse Keys to be turned on or off from the keyboard by checking or unchecking the "Press the Option key five times to turn Sticky Keys on or off" check box.
4.	Use the Initial Delay slider to set the amount of time a key must be pressed before the pointer starts moving. Move the slider to the left to make the pointer start moving sooner when a key is pressed or to the right to increase the delay.
5.	Use the Maximum Speed slider to determine how fast and far the pointer moves when a key is pressed. Drag the slider to the right to increase the speed of movement or to the left to decrease it.
6.	To change the size of the pointer on the screen, use the Cursor Size slider. Drag the slider to the right to increase the size of the cursor (see Figure 9.6). Figure 9.6. You can increase the size of the cursor if someone who uses your Mac has difficulty seeing the standard pointer.
