[AUCTeX] Modify environments interactively

[Roy Crihfield]

Is there a function that allows quickly renaming, deleting or otherwise 
modifying an enclosing environment? If such a thing is built-in I would 
find it very useful.

Making LaTeX-modify-environment interactive would be one solution for 
this. If this sounds interesting I may have time to write up a patch. 
But first I'd like to know if something else exists.

Regards,
Roy
