Please restore compatibility between the Mac OS accessibility key strokes and Adobe pdf reader/editing software. The Mac OS keystrokes opt+esc definitely don't work within Acrobat Pro. Within Acrobat the system just reads the title of the document and stops. When I take the same pdf file and open it in an alternate software like Preview, the key strokes work to read selections aloud. Please fix this bug. Afterall, you don't want users to give up on your software and use other products to get around Acrobat accessibility issues, right? :)
