Scrolling automatically

mouse actions.
To scroll automatically through a document:
1. Choose View > Automatically Scroll.
2. Do any of the following:
●
To change the scrolling speed, press a number key (9 is the fastest and 0 is the slowest), or
press the Up Arrow or Down Arrow key.
●
To reverse the direction of the scrolling, press the hyphen or minus sign key.
●
To jump to the next or previous page, press the Left Arrow or Right Arrow key.
To stop automatic scrolling, press Esc or choose View > Automatically Scroll again.
