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

    <para>When you start a GNOME Desktop session for the first time,
    you should see a default startup screen, with panels, windows, and
    various icons.</para>

          <para>Panels are areas in the GNOME Desktop from which you
          can access all of your system applications and menus. Panels are very
          configurable.</para>
          <para>A particularly important panel is the top edge panel. The top
          edge panel includes the <application>Menu Bar</application>. The
          <application>Menu Bar</application> contains two special menus, as
          follows:</para>
          <itemizedlist>
            <listitem><para><guimenu>Applications</guimenu> menu: Contains all

        <listitem>
          <para>You can access all GNOME Desktop functions through menus. You
          can use the <guimenu>Applications</guimenu> menu to access almost all
          of the standard applications, commands, and configuration options.
          You can access the <guimenu>Applications</guimenu> menu from the
          <guimenu>Main Menu</guimenu> and from the <application>Menu
          Bar</application> applet.  You can add the <guimenu>Main
          Menu</guimenu> and the <application>Menu Bar</application>
          applet to your panels.</para>
          <para>The <application>Menu Bar</application> applet contains an
          <guimenu>Actions</guimenu> menu.  The <guimenu>Actions</guimenu>
          menu contains commands that perform various functions, for example
          <guimenuitem>Search for Files</guimenuitem> and <guimenuitem>Log
          Out</guimenuitem>.  The items in the <guimenu>Actions</guimenu>
          menu are at the top level of the
          <guimenu>Main Menu</guimenu>.</para>

          desktop.  The desktop is an active component of the user interface.
          You can place objects on the desktop to access your files and
          directories quickly, or to start applications that you use often.
          You can also right-click on the desktop to open a menu.</para>

    <para>The components of the GNOME Desktop are interoperable. Usually, you

    start applications from panels, from menus, or from the desktop.</para>
    <para>Your system administrator can make configuration changes to suit your
    needs, so that the GNOME Desktop that you use 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 GNOME 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>Some of the features of GNOME-compliant applications are as follows:</para>

      <listitem>
        <para>Consistent look-and-feel</para>
        <para>GNOME-compliant applications have a consistent look-and-feel. GNOME-compliant
applications use the look-and-feel settings that you specify in the preference
tools. You can use the following tools to change the look-and-feel of your
GNOME-compliant applications:<itemizedlist><listitem><para><application>Menus &amp; Toolbars</application> preference
tool</para></listitem><listitem><para><application>Theme</application> preference tool</para></listitem></itemizedlist></para>
      </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 screen. For example, you can detach the menubar, toolbar, and
location bar in the file manager. </para>

      <listitem>
        <para>Default shortcut keys</para>
        <para>GNOME-compliant applications use the same shortcut keys to perform the
same actions. For example, to quit a GNOME-compliant application, press <keycombo><keycap>Ctrl</keycap><keycap>Q</keycap></keycombo>. To undo an action in a GNOME-compliant
application, press <keycombo><keycap>Ctrl</keycap><keycap>Z</keycap></keycombo>. </para>
      </listitem>
      <listitem>
        <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>
