Vim-) while confirming and searching for replacement

When performing simple global search replacement, you can use the following ex command:

: % S/which/what/g

It is easy to use

%	Each row (everyline)
S	Replace (substitue)
Which	Search content
What	Replaced content
G	Global on that line)

In this way, you can quickly implement the global search and replacement function, but sometimes we do not want to complete all the replacement operations at a time, it is possible that we only want to replace a part.

To implement this operation, we first think of the execution sequence as search-> modify? -> Modify-> Find Next-> modify? -> Modify.

The specific commands can be executed in the following order:

/Which	Search
Cwwhat [ESC]	Chang word
N	Next, no need to replace
N	Proceed to the next step and modify it.
.	. (Dot) is used to repeat the previous operation, that isCwwhat [ESC]
