Accessibility options
The Accessibility Setup Assistant helps you select several options that improve
accessibility in Acrobat, particularly if you use assistive technologies. You can manually
select additional options in various panels of the Preferences dialog box. The Accessibility
Assistant includes the following options:
Note: Some options may not be available, depending on the type of assistive device you
specify; the assistant presents only options that are appropriate for your device.
Use High-Contrast Colors For Document Text
When selected, you can choose from a list of contrasting color combinations for text and
background, or create your own. (See
Using high-contrast colors .)
Disable Text Smoothing
Makes text sharper and easier to read with a screen magnifier.
Default Display Zoom
Set a percentage value (8.33-6400) to magnify documents on the screen. Allows low-
vision readers to read reflowed PDF documents more easily.
Always Use The Keyboard Selection Cursor
Keeps the pointer on automatically instead of requiring the user to select the Select tool
after a PDF document opens. Select this option if you use a screen magnifier.
Reading Order (for untagged documents)
Specifies the reading order of untagged documents. (See Selecting a reading order .)
Override The Reading Order In Tagged Document
Uses the reading order specified in the Reading Preferences instead of that specified by
the tag structure of the document. Use only when encountering problems in poorly tagged
PDF documents. (See
Selecting a reading order .)
Confirm Before Adding Tags To Document
When selected, Acrobat lets the user confirm the options that will be used before it
prepares an untagged document for reading by assistive technology. Tagging can be a
time-consuming procedure, particularly in larger documents.
Deliver Pages Or Document
Deliver Currently Visible Pages opens one page or a few pages at a time (Page Only
mode); Deliver The Entire Document At Once opens the entire document and may
negatively affect performance; Deliver All Pages Only For Small Documents lets Acrobat
selectively switch to Page Only mode if the document exceeds the page number limit that
you set in Maximum Number Of Pages In A Small Document. Page Only mode is
recommended for use with screen magnifiers but requires that you use keystroke
commands in Acrobat (not in the screen magnifier) to navigate to new pages.
Disable Document Auto-Save
Select to disable the auto-save function. Each time a PDF document is auto-saved, the
screen reader or magnifier must reload the document.
Reopen Documents To The Last Viewed Page
Allows you to save your place in the document for the next time you open it.
Display PDF Documents In The Web Browser
Opens PDF documents from the Internet in the web browser instead of a separate Acrobat
window. Deselect for greater control when navigating a document in a screen reader.
