  <title>Use gestures on touchpads and touchscreens</title>

  <p>Multitouch gestures can be used on touchpads and touchscreens for system navigation,
  as well as in applications.</p>

  <p>A number of applications make use of gestures. In
  <app>Document Viewer</app>, documents can be zoomed and swiped with gestures,
  and <app>Image Viewer</app> allows you to zoom, rotate and pan.</p>
