+ <para>
+ Your <application>Control Center</application> may contain

+ </para>
+ <para> <application>Control Center</application> is a part of

+ <filename>control-center</filename> package. This manual

+ <title>Using the Control Center</title>
+ <para>
+ The <application>Control Center</application> is divided into
+ two main sections, the menu of configurable capplets on the
+ left and the main work space on the right. The capplets in the
+ menu are grouped in sections, such as
+ <guilabel>Desktop</guilabel>, <guilabel>Multimedia</guilabel>,
+ etc. Each of these sections is discussed in detail below. As
+ with all menus of this type, you can <quote>collapse</quote> a
+ whole section by clicking on the small downward triangle to
+ the left of the section title. To expand a collapsed section,
+ click on the triangle again.
+ </para>
+ <para>
+ Working with the <application>Control Center</application>
+ simply requires you to select a capplet from the menu on the
+ left and click on it. Once this is done, the workspace will
+ change, allowing you to configure the item.
+ </para>
+ <para>After you have made the configuration changes, you can
+ press <guibutton>OK</guibutton> button to confirm the changes
+ or <guibutton>Cancel</guibutton> to return to the old
+ configuration. It you want to test the new settings before
+ making your decision press <guibutton>Try</guibutton> button;
+ this will apply the new cofiguration settings so that you can
+ see what they would look like, but it also remembers the old
+ ones. After you have tried the new settings, you can press
+ <guibutton>OK</guibutton> button to make them permanent, or
+ <guibutton>Revert</guibutton> to return to the old

+ <para>
+ <guilabel>Dialog position</guilabel> &mdash; This will let you
+ choose how the dialogs appear when launched. You can let the
+ window manager decide for you (or how you have defined it in
+ the window manager configuration), center the dialogs on the
+ screen, or drop them where the mouse pointer is when they
+ are launched.
+ </para>
+ <para>
+ <guilabel>Dialog hints</guilabel> &mdash; This will let you change
+ the behavior of the dialog hints which are the tooltips that
+ appear when you move your mouse button over a button or part
+ of the dialog. You may choose to have hints handled like
+ other windows, or let the window manager decide how to
+ display them.
+ </para>
+ <para>
+ <guilabel>Place dialogs over application window when
+ possible</guilabel> &mdash; You may choose to place dialog over
+ the applications when possible which will help you keep your
+ windows organized on your screen If you are familiar with
+ other operating systems you may wish to keep this selected
+ as this is how most operating systems handle dialogs.

+ The MDI capplet allows you to change the MDI mode for Gnome
+ applications. MDI stands for Multiple Document Interface
+ and refers to the way more than one document is displayed in
+ Gnome applications.

+ <title>IMPORTANT</title>
+ <para>
+ Although this capplet gives you great control over the
+ look and feel of your applications you should consider
+ these tools for advanced use only.
+ </para>
+ </important>
+ <para>
+ The default style in Gnome-compliant applications for MDI is
+ usually tabs or <quote>notebook</quote>: it looks like an
+ address book, your documents are <quote>leaves</quote> of
+ this notebook, and you switch between them by using the
+ tabs. If you do not like
+ the tab look you may change it here.
+ </para>
+ <para>
+ <guilabel>Default MDI Mode</guilabel> &mdash; In addition to
+ <guilabel>Notebook</guilabel>, you will find
+ <guilabel>Toplevel</guilabel> and
+ <guilabel>Modal</guilabel>. <guilabel>Notebook</guilabel> is the
+ default tab look described above;
+ <guilabel>Toplevel</guilabel> displays only the active
+ document on the top view until it is closed and
+ <guilabel>Modal</guilabel> has only one toplevel which can
+ contain any of the documents at any one time, however only
+ one can be displayed. If you have ever used
+ <application>Emacs</application>, <guilabel>Modal</guilabel>
+ is very similar to the way <application>Emacs</application>
+ handles buffers.
+ </para>
+ <para>
+ <guilabel>MDI notebook tab position</guilabel> &mdash; If
+ you choose to use the <guilabel>Notebook</guilabel> style
+ you may then decide where you want the tabs to appear in
+ your applications. You may have them at the top, left,
+ right, or bottom of your application. Keep in mind that
+ these choices will affect only applications that are Gnome
+ compliant.
