I actually think what you want is to leave the tab key alone, and the  
same for the other keys, and to just write a trivial 3 line script to  
do the kind of change you need to the entire document whenever it's  
run. (I think someone already suggested something similar). Then,  
assuming you use some sort of svn type system, you should be able to  
have a pre/post-commit hook or whatnot that runs this script.
