technology. Because Acrobat sends page information about all visible pages, the assistive technology receives
information about pages that may be only partially visible (such as the bottom of one page or the top of the next), as
well as those pages that are completely visible. If you use a page display setting other than Single Page, such as
Continuous, and then you display the next page, the technology may not correctly track which portion of a previous
page it has already read aloud. For instructions on setting the default page layout to Single Page, see
Preferences for
viewing PDFs .
This option corresponds to the Only Read The Currently Visible Pages option in the Accessibility Setup Assistant.
Read The Entire Document This option can be best if you use a screen reader that has its own navigation and search
tools and that is more familiar to you than the tools in Acrobat. This option corresponds to the Read The Entire
Document At Once option in theAccessibility Setup Assistant.
For Large Documents, Only Read The Currently Visible Pages This option is selected by default and is usually best if
you use a screen reader with long or complex PDFs. It allows Acrobat to deliver an entire small document but revert to
page-by-page delivery for large documents. This preference corresponds to the For Large Documents, Only Read The
Currently Visible Pages option in the Accessibility Setup Assistant.
Confirm Before Tagging Documents When selected, lets the user confirm the options that are used before Acrobat
prepares an untagged document for reading. Tagging can be a time-consuming procedure, especially for larger
documents. This preference corresponds to the Confirm Before Tagging Documents option in the Accessibility Setup
Assistant.
Read Out Loud Options Set preferences in to control volume, speed, and pitch of the voice used for Read Out Loud. You
can choose to use the default voice or any of the voices that your operating system provides. You can also use the up
and down arrows to read blocks of text. These preferences do not have corresponding options in theAccessibility Setup
Assistant.
Navigate and control the application with the keyboard
You can navigate by using the keyboard instead of the mouse. Several keyboard access features are available in Mac OS;
see the documentation for your operating system for details.In Windows, some of the keyboard shortcuts used to
navigate in Acrobat differ from the keyboard shortcuts used in other Windows applications.
When you open Acrobat within a web browser, keyboard commands are mapped to the web browser first.
Consequently, some keyboard shortcuts are not available in Acrobat or are available only after you shift the focus to the
PDF.
For information about accessibility features, see www.adobe.com/accessibility .
Enable single-key accelerators
You can select some tools and perform some actions with single-key accelerators. Most keyboard shortcuts in Acrobat
don’t require that you enable single-key accelerators.
❖ In the Preferences dialog box under Categories, select General, and then select Use Single-Key Accelerators To
Access Tools.
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.
Choose View > Page Display > Automatically Scroll.
