  <title>Click, drag, or scroll with the touchpad</title>

  <p>Bạn có thể nhấn, nhấp đúp, kéo và cuộn bằng touchpad mà không cần nút cứng.</p>

<section id="tap">
  <title>Tap to click</title>

  <p>You can tap your touchpad to click instead of using a button.</p>

  <steps>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Mouse &amp; Touchpad</gui>.</p>
    </item>
    <item>
      <p>Click on <gui>Mouse &amp; Touchpad</gui> to open the panel.</p>
    </item>
    <item>
      <p>In the <gui>Touchpad</gui> section, check <gui>Tap to click</gui>.</p>
      <note>
        <p>The <gui>Touchpad</gui> section only appears if your system has a
        touchpad.</p>

  <list>
    <item>
      <p>Để nhấn, gõ nhẹ lên touchpad.</p>
    </item>
    <item>
      <p>Để nhấp đúp, gõ nhẹ nhanh hai lần.</p>
    </item>
    <item>
      <p>To drag an item, double-tap but don't lift your finger after the
      second tap. Drag the item where you want it, then lift your finger to
      drop.</p>
    </item>
    <item>
      <p>If your touchpad supports multi-finger taps, right-click by tapping
      with two fingers at once. Otherwise, you still need to use hardware
      buttons to right-click. See <link xref="a11y-right-click"/> for a method
      of right-clicking without a second mouse button.</p>
    </item>
    <item>
      <p>If your touchpad supports multi-finger taps,
      <link xref="mouse-middleclick">middle-click</link> by tapping with three
      fingers at once.</p>
    </item>
  </list>

  <note>
    <p>When tapping or dragging with multiple fingers, make sure your fingers
    are spread far enough apart. If your fingers are too close, your computer
    may think they're a single finger.</p>

<section id="twofingerscroll">
  <title>Two finger scroll</title>

  <p>You can scroll using your touchpad using two fingers.</p>

  <steps>
    <item>
      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Mouse &amp; Touchpad</gui>.</p>
    </item>
    <item>
      <p>Click on <gui>Mouse &amp; Touchpad</gui> to open the panel.</p>
    </item>
    <item>
      <p>In the <gui>Touchpad</gui> section, check <gui>Two finger
      scroll</gui>.</p>
    </item>
  </steps>

  <p>When this is selected, tapping and dragging with one finger will work as
  normal, but if you drag two fingers across any part of the touchpad, it will
  scroll instead. Move your fingers between the top and bottom of your touchpad
  to scroll up and down, or move your fingers across the touchpad to scroll
  sideways. Be careful to space your fingers a bit apart. If your fingers are
  too close together, they just look like one big finger to your touchpad.</p>

  <note>
    <p>Cuộn hai ngón có thể không hoạt động trên mọi touchpad.</p>

<section id="contentsticks">
  <title>Natural scrolling</title>

  <p>You can drag content as if sliding a physical piece of paper using the
  touchpad.</p>

      <p>Open the <gui xref="shell-introduction#activities">Activities</gui> overview and
      start typing <gui>Mouse &amp; Touchpad</gui>.</p>
