To scroll through a document or web page when you are working in a session, use the scroll gesture. The scroll gesture emulates the middle scroll wheel on a mouse.
To use the scroll gesture, drag upwards or downwards with two fingers.
An alternative way to scroll through a document or web page is to use the scroll bars on the application window.
See Section 2.4, “Using Gestures in a Session” for details of the supported gestures when you are working in a session.
