APIs for programming text editors

An important aspect of my project involves the mechanics of programming a text editor under Eclipse. I must say that I haven't found a comprehensive tutorial on this (if there ever can be). If all goes well with my project, even less people will need to know about these APIs :) In the meantime, helpful docs include:

• A talk at EclipseCon 2004, Text Editors and How to Implement Your Own by Kai-Uwe Mätzel
• The EclipseCon 2006 tutorial Text Editor Recipes (by Tom Eicher and Martin Aeschlimann) and its slides
  

Don't worry! More references will come later! (and will be available as URLs in commented source code). Want tutorials? I've found these useful:
