With the Mouse preference tool you can:
Use the General tabbed section to specify whether the mouse buttons are configured for left-hand or right-hand use and configure the speed and sensitivity of your mouse.
Table 8-11 lists the general mouse preferences that you can modify.
| Dialog Element | Description |
|---|---|
| Right-handed | Select this option to configure your mouse for right-hand use. When you configure your mouse for right-hand use, the left mouse button is the primary button and the right mouse button is the secondary button. |
| Left-handed | Select this option to configure your mouse for left-hand use. When you configure your mouse for left-hand use, the functions of the left mouse button and the right mouse button are swapped. |
| Show position of pointer when the Control key is pressed |
Select this option to enable a mouse pointer animation when you press and release the Control key. This feature can assist you to locate the mouse pointer. The position of the Control key on the keyboard can be modified in the Keyboard Layout Options dialog, see Section 8.4.1.3 ― Keyboard Layout Options. |
| Acceleration | Use the slider to specify the speed at which your mouse pointer moves on your screen when you move your mouse. |
| Sensitivity | Use the slider to specify how sensitive your mouse pointer is to movements of your mouse. |
| Threshold | Use the slider to specify the distance that you must move an item before the move action is interpreted as a drag-and-drop action. |
| Timeout |
Use the slider to specify the amount of time that can pass between clicks when you double-click. If the interval between the first and second clicks exceeds the time that is specified here, the action is not interpreted as a double-click. Use the light bulb icon to check double-click sensitivity: the light will light up briefly for a click, but stay lit for a double-click. |
Use the Accessibility tabbed section to configure accessibility features that can help people who have difficulty with exact positioning of the pointer or with pressing the mouse buttons:
A single click of the primary mouse button
A double click of the primary mouse button
A click that begins a drag operation
A single click of the secondary mouse button
