Shepherding electrons

Eagle is a pretty useful piece of software for designing circuit schematics and PCBs.  I don't use it often enough to get really good at it however, and there are certain things in Eagle that I find myself having to "google" every time I want to do it!  So without further ado, this is my growing list of Eagle tips, in no particular order:
