      <p>To drag an item, double-tap but don’t lift your finger after the

      <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>

  <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>

  <title>Two finger scroll</title>

  <media src="figures/touch-scroll.svg" its:translate="no" style="floatend"/>

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

  <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>

  <title>Edge scroll</title>

  <media src="figures/touch-edge-scroll.svg" its:translate="no" style="floatend"/>

  <p>Use edge scroll if you want to scroll with only one finger.</p>

  <p>Your touchpad's specifications should give the exact
  location of the sensors for edge scrolling. Typically, the vertical
  scroll sensor is on a touchpad's right-hand side. The horizontal
  sensor is on the touchpad's bottom edge.</p>

  <p>To scroll vertically, drag your finger up and down the right-hand
  edge of the touchpad. To scroll horizontally, drag your finger across
  the bottom edge of the touchpad.</p>

  <note>
    <p>Edge scrolling may not work on all touchpads.</p>
