Setting up full keyboard access (Mac OS only)
In Mac OS, you can navigate and interact within the Adobe Reader work area and Adobe
PDF documents by setting up the appropriate system-level preferences.
To set up full keyboard access:
1. On the Apple menu, choose System Preferences, and select Keyboard & Mouse (Mac OS
10.3) or Keyboard (Mac OS 10.2).
2. Click the Keyboard Shortcuts tab (Mac OS 10.3) or Full Keyboard Access tab (Mac OS
10.2).
3. Select the Turn On Full Keyboard Access option.
4. Do one of the following:
In Mac OS 10.3, choose System Preferences from the Apple menu, select Universal
Access, and then select either Enable Access For Assistive Devices to use installed screen
reader technology or Enable Text-To-Speech For Universal Access to use the Mac OS
speech technology.
In Mac OS 10.2, select Any Control and then exit the System Preferences.
When you open Adobe Reader within a web browser, keyboard commands are mapped
first to the web browser. Consequently, some keyboard shortcuts may not be available for
Adobe Reader or may not be available until after you shift the focus to the PDF document.
