For example, to make a non-text document content available to a screen reader, the PDF should contain alternate text for figures and replacement (actual) text for some links, formulas and abbreviations. There are several ways to add alternative text to images and figures: • The "Set Alternative Text" command in the Accessibility tool • The "Set Alternative Text" command in the Make Accessible Actions wizard • The Touch Up Reading Order tool (refer to "Add Alternate Text with the Touch Up Reading Order Tool" on page 61). • The alternative text field of the Object Properties dialog in the Tags panel Note: Alternate/Actual text should be short and concise. The Alternative Text field should be used to set alternative text for figure elements. The Alternative Text field is not announced by screen readers for non-image element. The Actual Text field is announced instead when it is present on a text element. Adobe® Acrobat® XI Pro Accessibility Guide: Best Practices for PDF Accessibility 76
