Well that didn't work...

I think he is trying to create an auto-indent editor, kind of like the 
Rev IDE editor, only one that actually works.

I wrote my own auto-indent editor years ago.  I know it can be done 
(although perhaps not in Rev).  Too bad they gave up before they had 
finished the project.
