server. A proxy server is a server that intercepts requests to another server,

    <para>A
theme is a group of coordinated settings that specifies the visual appearance
of a part of the desktop environment. You can choose themes to change the
appearance of the desktop environment. Use the <application>Theme</application>
preference tool to select a theme for your desktop environment. You can choose
from a list of available themes. The list of available themes includes several
themes for users with accessibility requirements. </para>
    <para>A theme contains settings that affect different parts of the GNOME desktop,

The controls setting for a theme determines the visual
appearance of windows, panels, and applets. The controls setting also determines
the visual appearance of the GNOME-compliant interface items that appear on
windows, panels, and applets, such as menus, icons, and buttons. Some of the
controls setting options that are available are designed for special accessibility
needs. You can choose an option for the controls setting from the <guilabel>Controls</guilabel> tabbed section in the <application>Theme</application>
preference tool.</para>
