Note: Some screen readers do not work with Acrobat single-key accelerators.
Scroll automatically
The automatic scrolling feature makes it easier to scan through long PDFs, especially reflowed documents. You can
scroll through pages without using keystrokes or mouse actions.
1 Choose View > Page Display > Automatically Scroll.
2 Do any of the following:
• To change the scrolling speed to a specific speed, press a number key (9 for fastest, 0 for slowest).
• To increase or decrease the scrolling speed, press the Up Arrow or Down Arrow key, depending on the direction
of scrolling.
• To reverse the direction of scrolling, press the 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 > Page Display > Automatically Scroll again.
Save as accessible text for a braille printer
Note: This document uses the term “braille printer” to refer to any device that is used to convert accessible text to a form
that can be used by a person with blindness or low vision.
You can save a PDF as accessible text to print on a braille printer. Accessible text can be imported and printed out as
formatted grade 1 or 2 braille documents by using a braille translation application. See the documentation included
with the braille translator for more information.
A text version of a PDF contains no images or multimedia objects, although the text version of an accessible PDF
contains alternate text descriptions for such objects if they have been provided.
❖ Choose File > Save As > More Options > Text (Accessible).
Reflow a PDF
You can reflow a PDF to temporarily present it as a single column that is the width of the document pane. This reflow
view can make the document easier to read on a mobile device or magnified on a standard monitor, without scrolling
horizontally to read the text.
You cannot save, edit, or print a document while it is in Reflow view.
In most cases, only readable text appears in the reflow view. Text that doesn’t reflow includes forms, comments, digital
signature fields, and page artifacts, such as page numbers, headers, and footers. Pages that contain both readable text
and form or digital signature fields don’t reflow. Vertical text reflows horizontally.
Acrobat temporarily tags an untagged document before reflowing it. As an author, you can optimize your PDFs for
reflow by tagging them yourself. Tagging ensures that text blocks reflow and that content follows the appropriate
sequences, so readers can follow a story that spans different pages and columns without other stories interrupting the
flow.
To quickly check the reading order of a document, view it in Reflow view.
