    <para>This chapter introduces you to the features and main components
of the GNOME desktop. Before you start to use the desktop read this chapter
to familiarize yourself with the various features, and how the main components
work. The desktop is very configurable, so this chapter describes the typical

    <para>The major components of the desktop are as follows: <itemizedlist><listitem><para>Panels</para><para>Panels are areas on your desktop from which you can access all of your
system applications and menus. Panels are very configurable.  A particularly
important panel in <xref linkend="gosoverview-FIG-1"/> is the Menu Panel. The
Menu Panel stretches the full width of the top edge of the desktop. The Menu
Panel includes two special menus, as follows:</para><itemizedlist><listitem><para><guimenu>Applications</guimenu> menu: Contains all applications
and configuration tools. This menu also includes the file manager and the
help browser. To start the file manager, choose <guimenuitem>Home Folder</guimenuitem> from the <guimenu>Applications</guimenu> menu.</para></listitem><listitem><para><guimenu>Actions</guimenu> menu: Contains various commands

You can use the <guimenu>Applications</guimenu> menu and the <guimenu>Actions</guimenu> menu to access almost all of the standard applications, commands,
and configuration options. </para><para>You can also access almost all of the standard applications, commands,

A workspace is a discrete area on the desktop in which you can work. You can

You can use the file manager to manage your files and folders. </para></listitem><listitem><para>Desktop background</para><para>The desktop background lies behind all of the other components on the
desktop. The desktop background is an active component of the user interface.
You can place objects on the desktop background to quickly access  your files
and directories, or to start applications that you use often. You can also
right-click on the background to open a menu.</para></listitem><listitem><para><guilabel>Start Here</guilabel> location</para><para>The <guilabel>Start Here</guilabel> location provides an access point
to some of the key features of the GNOME desktop. You can access your GNOME
applications and configuration tools from the <guilabel>Start Here</guilabel>
location. You can also access programs that enable you to configure your system
as a server, and to choose other system settings.</para></listitem><listitem><para>Desktop preferences</para><para>The GNOME desktop contains dedicated <firstterm>preference tools</firstterm>.
Each tool controls a particular part of the behavior of the desktop. To start
a preference tool, choose <menuchoice><guimenu>Applications</guimenu><guimenuitem>Desktop Preferences</guimenuitem></menuchoice>. Choose the item
that you want to configure from the submenus.</para></listitem></itemizedlist></para>
    <para>The most powerful features of the desktop are the high degree of configurability
and the multiple ways that you can perform tasks.</para>
    <para>The desktop provides interoperability of the desktop components. Usually,
you can perform the same action in several different ways. For example, you
can start applications from panels, from menus, or from the desktop background.</para>
    <para>Your system administrator can make configuration changes to suit your
needs, so that the desktop might not be exactly the same as described in this
chapter. Nevertheless, this chapter provides a useful quick guide to how to
work with the desktop. </para>

    <para>The applications that are provided with the GNOME desktop
share several characteristics. For example, the applications have a consistent
look-and-feel. The applications share characteristics because the applications
use the same programming libraries. An application that uses the standard
GNOME programming libraries is called a <firstterm>GNOME-compliant application</firstterm>. For example, <application>Nautilus</application> and the <application>gedit</application> text editor are GNOME-compliant applications.</para>
    <para>GNOME provides libraries in addition to the libraries provided by your
operating system. The libraries enable GNOME to run your existing applications
as well as GNOME-compliant applications. For example, if your operating system
is UNIX-based, you can run your current X11 applications and Motif applications
from the GNOME desktop.</para>

        <para>GNOME-compliant applications have a consistent look-and-feel. GNOME-compliant

preference tools. You can use the following tools to change the look-and-feel

      </listitem>
      <listitem>
        <para>Menubars, toolbars, and statusbars</para>
        <para>Most GNOME-compliant applications have a menubar, a toolbar, and a statusbar.
The menubar always contains a <guimenu>File</guimenu> menu and a <guimenu>Help</guimenu> menu. The <guimenu>File</guimenu> menu always contains an <guimenuitem>Quit</guimenuitem> menu item, and the <guimenu>Help</guimenu> menu always
contains an <guimenuitem>About</guimenuitem> menu item.</para>
        <para>A <firstterm>toolbar</firstterm> is a bar that appears under the menubar.
A toolbar contains buttons for the most commonly-used commands. A <firstterm>statusbar</firstterm> is a bar at the bottom of a window that provides information
about the current state of what you are viewing in the window. GNOME-compliant
applications might also contains other bars. For example, <application>Nautilus</application> contains a location bar.</para>
        <para>Some of the bars in GNOME-compliant applications are detachable. That
is, the bar has a handle that you can grab then drag the bar to another location.
You can drag the bar to snap to another side of the window, or to another
part of the desktop. For example, you can detach the menubar, toolbar, and
location bar in the file manager. </para>

        <para>Drag-and-drop</para>
        <para>GNOME-compliant applications use the same protocol to implement drag-and-drop
operations. Therefore, GNOME-compliant applications provide consistent feedback
when you drag-and-drop items.</para>
        <para>The use of the same protocol also enables GNOME-compliant applications
to interoperate in a sophisticated manner. For example, GNOME-compliant applications
recognize the format of the items that you drag. When you drag a HTML file
from a <application>Nautilus</application> window to a web browser, the file
is displayed in HTML format in the browser. However, when you drag the HTML
file to a text editor, the file is displayed in plain text format in the text
editor. </para>
