After running the Accessibility Checker you will be given a report. Two items will always show up on the report as manual checks:

• Logical Reading Order
• Color Contrast

Use the chevrons to the left of an item to expand it for additional information. Right-click for a submenu that will give you the following options:

• Fix: Acrobat either fixes the item automatically or displays a dialog box prompting you to fix the item manually.
• Skip Rule: Deselects this option in the Accessibility Checker Options dialog box for future checks of this document, and changes the item status to Skipped.
• Explain: Opens the online Help where you can get more details about the accessibility issue.
• Check Again: Runs the checker again on all items. Choose this option after modifying one or more items.
• Show Report: Displays a report with links to tips on how to repair failed checks.
• Options: Opens the Accessibility Checker Options dialog box, so you can select which checks are performed.
