I would like to substitute a word in-place. For example, after yanking some word by pressing yw and then setting a cursor on some other word, I would like to press something so that substitution will happen. (e.g. SOME_KEYw where w is really w and SOME_KEY is some key). I would not like to switch into Insert Mode.
I am not interested in the
:%s/oldword/newword/gc solution. I need interactive in-place substitution!
