Let me start off by saying that i know nothing about linux, its operations, or its extensions. I know so little of this that, in fact, I'm not sure where to even go to learn about this stuff and it's relevance to the iLiad (and btw, if anyone can point me to a good guide to that, I'd be much obliged

).
That being said, I am having a bit of trouble operating my iLiad with some of the custom functions (when I can get them to work at all).
I followed the
https://www.mobileread.com/forums/showthread.php?t=17342 Noob guide to install the developer's program, so I have that. My main question is, is there any way to open a blank page in the middle of a PDF? I'm a student, and I'm using my iLiad to scribble on the slides that my professors post online, which are usually in PDF format. However, when a slide doesn't have enough room, is there any way that I can open up a new note page in the middle of the document so I can continue writing?
