So I was trying out another PDF reader just for the hell of it, and was confused about highlighting (There was a tool in the ribbon bar that I was too stupid to use).
Instead of looking through documentation, I actually tried to use the built-in AI to see what wisdom it could offer a peasant like me.
On the same subject, are there any open source PDF readers you can recommend?
Agreed. We've incorporated PDFGear at our workplace for satellite locations that are too small for bundled Adobe packages, and made it available on most employee computers. Solid software for something that would otherwise cost ~$120/head yearly.
