Windows/Mac/Linux: Free, open source application KeyJnote transforms any simple PDF into a powerful interactive presentation similar to PowerPoint or Keynote. After you plug your PDF into KeyJnote, you get a slate of powerful presentation tools, with everything from simple forward and back navigation with your left and right mouse buttons, mouse highlighting, rectangle highlighting, slide zooming, and more. KeyJnote doesn’t yet have a graphical interface for starting a PDF presentation, but using it is simple.
The easiest way to get going with KeyJnote is probably to drag your PDF into your KeyJnote directory, fire up a command prompt in that folder, type
keyjnote yourpdfnamehere.pdf, and your presentation will automatically start up. For a quick example of KeyJnote in action, try the demo PDF by running
keyjnote demo.pdf from the command prompt or terminal in the KeyJnote directory. Thanks jackhab! UPDATE: Our apologies if this one looks familiar.
