  </highlights>
  <!-- move the following to its own section, "Using Pref Tools"? -->
  <para>选项工具是一个小应用程序，允许您改变 GNOME 桌面设置。每个选项工具对应一个特定的外观设置。例如，在<application>鼠标</application>选项工具里，您可以设置鼠标是左手习惯还是右手习惯，或者改变点击速度。用<application>窗口</application>选项工具，您可以设置用鼠标点击窗口时，窗口的行为变化。</para>
  <para>要打开一个选项工具，在顶部面板点击<menuchoice><guimenu>系统</guimenu><guisubmenu>首选项</guisubmenu></menuchoice>。从子菜单里选择相应的工具菜单项。</para>
  <para>大多数情况下，当您改变设置后，效果会立刻实现，不需要关闭选项工具。您可以打开工具窗口，然后试着改变选项，从而可以尝试更多的变化。</para>
  <para>一些应用程序或系统组件也可以添加它们自己的首选项到这个菜单里。</para>
  <note><para>一些首选项工具可以让您修改系统关键部位，因此需要管理员的权限。当您打开首选项工具时，一个对话框将会提示您输入密码。在<menuchoice><guimenu>系统</guimenu><guisubmenu>系统管理</guisubmenu></menuchoice>子菜单中也包含了更加复杂的实用工具程序来管理和更新系统。</para></note>

    <para>You can configure the GNOME Desktop to connect to a <firstterm>proxy server</firstterm>,

    to another server, and fulfills the request itself, if it can. You can enter the domain name or
    the Internet Protocol (IP) address of the proxy server. A <firstterm>domain name</firstterm> is

    this more clear.</remark>
    <para>Since it is possible that you need to use a different proxy configuration in different places,
    <application>Network Proxy Preferences</application> allows you to define separate proxy configurations
    and switch between them using the <guilabel>Location</guilabel> drop-down box at the top of the window.
