Is there any way I can modify someone else's Adobe Reader document? Specifically, I would like to add keywords to the Properties of the document, purely for my own use. If I can't do this, is there any way I can copy the information to some other format where I can use my own keywords?
I'm using Adobe Reader 8.1.1, on a Macintosh with OS X Version 10.4.11.
Thanks in advance for your attention and information.
