What Does The 'e' Stand For

While bored I started extracting all the methods and functions in my program and moving them to a module...just trying to practice the encapsulation I've been hearing so much about. While trying to move my print functions it raised a couple questions. The issue was the 'e' in e.marginbounds and e.Graphics not being recognized. I caught 'e not declared' errors as if the system was just interpreting it as some kind of new variable. I tried moving the 'e' to several places just to experiment and the only place it seems that the intellisense would pop up with anything worth displaying was in the printDocument_printPage event itself.

what the 'e' stands for in these functions anyhow? Is it similar to the 'Me' in a Me.Close() being that it's just meant to address what's immediately at hand? Is there a way around this localization of the printing code, maybe an import of something that would make the 'e' accessible again. Such as the 'Imports System.IO' for the streamreader and writer functions.
