  <p>The <gui>menu bar</gui> is the dark strip on the top of your screen.
    It contains the window management buttons, the app menus, and the status menus.</p>

<section id="window-management">
  <title>Window management buttons</title>
  <p>The <gui>window management buttons</gui> are on the top left corner of windows. When
    maximized, the buttons are in the top left of the screen. Click the buttons to
    close, minimize, maximize or restore windows.</p>
</section>

<section id="app-menus">
  <title>App menus</title>
  <p>The <gui>app menus</gui> are by default located to the right of the window management buttons.
    Unity hides the app menus and the window management buttons unless you move your
    mouse pointer to the top left of the screen or press <keyseq><key>Alt</key><key>F10</key></keyseq>.
    This feature enables you to see more of your content at once, which is
    especially valuable on small screens like netbooks.
  </p>

  <p>If you want, you can change the default behavior to having your menus attached
    to the window title bar of respective application instead of the menu bar, and setting the visibility to always displayed instead of only displayed on mouse hovering. </p>

  <steps>
    <item>
      <p>Click the <gui>system menu</gui> at the very right of the <gui>menu bar</gui> and select
        <gui>System Settings</gui>.</p>
    </item>
    <item>
      <p>In the Personal section, click <gui>Appearance</gui> and choose the
        <gui>Behavior</gui> tab.</p>
    </item>
    <item>
      <p>Under <gui>Show the menus for a window</gui>, select <gui>In the window's title bar</gui>.</p>
    </item>
    <item>
      <p>Under <gui>Menus visibility</gui>, select <gui>Always displayed</gui>.</p>
    </item>
  </steps>

<section id="status-menus">
  <title>Status menus</title>
  <p>Ubuntu has several different <gui>status menus</gui> (sometimes referred to as
    <gui>indicators</gui>) on the right side of the menu bar.
    The status menus are a convenient place where you can check and modify the
    state of your computer and applications.</p>
