The Options tab (Figure 4-25) provides a number of additional choices related to the Energy

The Schedule button brings up a dialog box that allows you to designate times when you
want your computer to go to sleep and wake up automatically. For example, if you use your
computer in an office environment, you might want it to sleep in the evening after you leave and
wake up in the morning just before you arrive.
One final option is the lock in the lower-left corner of the preference pane. This is the first
time we’ve mentioned this in this book, although it’s a common feature in many preference panes
and applications. If you are an administrator on your computer, clicking this lock will lock the
preference pane so that changes cannot be made to it until it is unlocked. Clicking the locked
icon will present a standard authentication dialog box asking for your administrative password
to unlock the preference pane. In general, if other people use your computer and you don’t want
them monkeying around with important settings, lock them.
Keyboard & Mouse
CHAPTER 4 SYSTEM PREFERENCES 71
The Keyboard & Mouse preference pane controls the options for your mouse, keyboard, and
trackpad. It is divided into five tabs each, providing options for your keyboard, trackpad,
mouse, Bluetooth setup, and keyboard shortcuts.
NOTE Certain tabs will only appear when certain hardware is available for your computer. For
example, the Trackpad tab will only show up if you have a trackpad attached to your system.
Even the Mouse tab won’t show up until you attach a mouse.
