I'm not sure if you want to interrupt the current replacement-replace operation and resume it again. But if that is acceptable, here is my suggestion:
- - , :
:%s/find/replace/gc - , ,
n, , <ctrl-C> <shift-N>, find- find-replace -, :
:.,$s/find/replace/gc
vim - .
. .,$ :s (substitute) , ( .), ( $).
2: , , , , - . % :s (substitute) .
