Okay, sorry; I assumed it as just a half-made wiki page. Looks like it's 
actually a different package. A better link for the pdf-tools I'm using is this 
awesome package: https://github.com/politza/pdf-tools (available through 
Melpa). 

yeah, C-g provides no response. I'll can look into trying a different emacs 
version; I usually just run with whatever my Linux repo (Fedora in this case) 
provides.
