Simple text editor that supports highlighting and font colours I'm looking for a standalone (or web) application that allows for very simple text editing, but also allows for personal annotation of the text by changing script colour and highlighting. Most text editors for developers doesn't allow for the above features, and Word/Pages is much too cumbersome. I'll be using it for some coding but it's primary use will be for DNA analysis (hence the annotation).

Does such an app exist?
TextEdit is part of Mac OS X. You can find it in the Applications folder.
