  <title>Scrollbar preferences</title>

  <p>A scrollbar is a part of the graphical user interface (GUI) which allows
  anything continuous and exceeding the visible screen space such as text to be
  viewable by the user by scrolling down to the parts hidden from current
  view.</p>

  <!-- Note to self: check UI. -->

  <section id="scrollbar-visibility">
    <title>Visibilidade da barra de desprazamento</title>

    <p>You can set the location of the scrollbar, or disable it, in
    <app>Terminal</app>:</p>

    <steps>
      <item>
        <p>Select <guiseq><gui style="menu">Edit</gui>
        <gui style="menuitem">Profile Preferences</gui>
        <gui style="tab">Scrolling</gui></guiseq>.</p>
      </item>
      <item>
        <p>You can choose from the following options:</p>
        <list>
          <item>
            <p><gui style="menuitem">Always visible</gui>: Scrollbar is
            visible at all times.</p>
            <!-- Scrollbar is not a proper noun, so do not capitalise it
            unless it is at the start of a sentence. -->
          </item>
          <item>
            <p><gui style="menuitem">Visible only when necessary</gui>:
            Scrollbar is visible only when terminal output exceeds the length
            of <app>Terminal</app> window size.</p>
          </item>
          <item>
            <p><gui style="menuitem">Hidden</gui>: Scrollbar is always hidden
            from view.</p>
          </item>
        </list>
      </item>
      <item>
        <p>Your preference is saved immediately. Click
        <gui style="button">Close</gui> to return to <app>Terminal</app>.</p>
      </item>
    </steps>

  </section>

  <section id="scrollback-lines">
    <title>Scrollback lines</title>

    <p><gui>Scrollback</gui> lines indicate the number of <app>Terminal</app>
    output lines stored in memory for scrolling.</p>

    <steps>
      <item>
        <p>Select <guiseq><gui style="menu">Edit</gui>
        <gui style="menuitem">Profile Preferences</gui>
        <gui style="tab">Scrolling</gui></guiseq>.</p>
      </item>
      <item>
        <p>In the input box next to <gui>Scrollback</gui>, input a number
        greater than 0 to set the number of scrollback lines.</p>
      </item>
      <item>
        <p>Optionally, you can click on <gui style="button">+</gui> to
        increase and <gui style="button">-</gui> to decrease lines.</p>
      </item>
    </steps>

    <p>To have unlimited scrollback lines, check
    <gui style="checkbox">Unlimited</gui> as your option.</p>

    <note style="warning">
      <p><gui style="checkbox">Unlimited</gui> scrollback lines could
      potentially overburden your computer's memory and make
      <app>Terminal</app> sluggish during scrolling!</p>
