I want to create a new theme. Is there documentation for DIV ID's that are required for AJAX functionality? If so, please point me in that direction. If not, could someone create it? Thanks a million!!!

Sorry, there's not very good documentation to begin with.

There are actually no "required" IDs. Take a look at how the current themes do it - just a little bit of JavaScript directly after the DIV that makes it into an editable AJAX div for either the title or the description.
