Use edge regions for seamless PDF interaction using finger touch gestures.

Configurable actions

Every touch region can be assigned the action that best fits your reading workflow.

Three gestures per region

Every region accepts a tap, long-press, or double-tap, with unique actions configurable for each gesture.

Adjustable region size

Touch region sizes are configurable, so the page edges can match your grip, hand size, and reading posture.

Invisible while reading

Touch regions are transparent during normal use. Show them only when configuring region sizes.

How it helps

Keep the document under your hands, like paper.

The touch regions make common navigation targets available from the PDF view margins, so you can read, highlight, and annotate without reaching for toolbars or breaking concentration.
