(2) Find
/pattern: to the tail
? PATTERN: To the header

S: In the last line mode, the search and replace operation is done within the bounds of the address;

s/what to look for/replace with content/modifiers
What to look for: Available modes
What to replace: You cannot use a pattern, but you can use a back reference symbol to refer to what the grouping brackets in the preceding pattern match to;
\1, \2, ...
&: Refers to the entire content of the "What to find" matches;
Modifier:
I: Ignore case
G: Global Substitution

/: Used for delimiters, so, to find the content or replace with the content that appears in this symbol, to use \ to escape it, use format: \/
The delimiter can be replaced with other characters: @, #等, for example;
