[TxMt] REQUEST: Scope-based Find/Replace

[Alain O'Dea]

I would find it incredibly useful if I could do a Find/Replace such  
that I could reliably rename symbols like variables and function  
names. I envision that this would be based on scopes and that it would  
constrain Find/Replace to exact matches of entire scopes. In Erlang  
this would enable me to rename variables by doing a Find/Replace of  
exact scope match for variable.other.erlang.
