Table-of-contents editing

[ACW at MIT-AI (Allan C. Wechsler)]

A very low priority but interesting idea:  there could be a mode
in which you could edit the table of contents of a text (presumably Bolio)
file.  It would simply display only the .chapters, .sections, and .subsections.
You could change chapters to sections, delete subsections, exchange sections,
rename things, etc, and in general screw yourself in amazing new ways.  How
hard would this be to implement?  Is there a similar functionality for
programs?  (Renaming functions, exchanging defuns, renaming arguments...)
