PDF Studio 10 introduces a new feature “Touch Mode” on touch screen enabled PC and Tablet devices including tablets and laptops such as the Windows Surface Pro, Dell Venue 11, or Lenovo Yoga 3 Pro. “Touch Mode” makes PDF Studio 10 more user friendly to edit and manage your PDFs using only your finger.
