Here's a list for gedit that was in a recent UBUNTU user magazine article:

I know, they're plugins, but that's a good place to keep features...

Try [url="http://www.linuxlinks.com/article/20080824052425167/Editors.html"]this website. It gives you a list of text editors in Linux, and when you click on them it gives you a detailed list of features and such. Hope that helps.

One editor conspicuous by its absence on the noted web site is Nedit, a grapical editor that is one of my favorites for general text and program editing. It has intelligent syntax highlighting for just about every language known, brace-matching, smart indenting, easy-to-use macro capabilities. It is currently hosted on SourceForge.net, but was developed at Fermi National Laboratory in Batavia, Illinois - our tax dollars at work! It is fully open source, and has about the best regular expression support for search/replace of any editor I know of. Anyway, it is definitely worth looking at for your paper.

For any project like that, a good start is to hit wikipedia as was suggested. In fact, if you have a moment, just enter "comparison of" and "list of" into wikipedia's serach engine. There are TONS of articles like that in there.
