It can be a good start, but the feature in the E editor is more general
than search and replace. You can perform any operation on the selected 
text. It's sort of like working on the narrowed part of a buffer, only 
the narrowed part in this case consists of several separate ranges of 
the same buffer (like all comments, etc.).
