Are there any basic text editors available that are just drop-dead simple, that allow me to instantly view the contents of a small text file? GEdit is nice, but it takes several seconds to start. I need something that is extreme bare-bones that doesn't have to load a bunch of features that can pop up and show the contents in the blink of an eye. Is there anything like that?

Edit: I'm looking for a GUI application that I can use to open a file from Nautilus.
