The Dock gives you easy access to often-used applications,
documents, and minimized windows. It can be customized to include specific
applications, folders, and documents that you use frequently. This allows
quick and easy access to these files any time you need them.
Customizing the Dock
To set the size of the Dock and
its items, drag the slider to adjust the size.
To enable Dock icon magnification,
check the box next to "Magnification." Then,
drag the slider to adjust the size. With magnification turned on, you
can point at an item in the Dock it will grow so you can see it better.
This is what it will look like with magnification on.
To change the position of
the Dock on the screen, select one of three options: Left, Bottom,
Right.
You can also change the effect that is displayed when
you minimize a window. The options are "Genie Effect" and "Scale Effect." While
the "Genie Effect" is cool, it uses more system resources than the
"Scale Effect." Thus, if you are
trying to save battery life, select the scale option.
Genie Effect
Shrinks
the window into the dock as if a genie was shrinking into a lamp.
Scale Effect
Just shrinks the icon into the dock
Checking the "Animate opening applications" box
will cause the applications
icon in the dock to bounce each time you open that application.

If you wish to save desktop
space, select the "Automatically hide and show
the Dock" option.
This will minimize the dock until you move your mouse to the edge of
the screen where the dock is positioned.
To add an item to the Dock, simply drag it to the desired position in
the Dock. You can also move items within the Dock to different positions.
If you wish to remove an item from the Dock, simply drag it off of the
dock and it will be removed permanently.
