(1) Address delimitation
: Start_pos[,end_pos]
#: A specific line of #, for example, 5 is the 5th line;
.: Current line;
$: last line;
#,#: Specifies the row range, the left is the starting line, the right side is the end line;
#,+#: Specifies the line range, the left side is the absolute number of the first row, and the right side is the offset from the left row number; For example: 3,+7
., $-1
1,$
%: Full text
/pattern/: The line from the beginning of the cursor to the first time the end of the file is matched by the pattern;
/first/,$
/PAT1/,/PAT2/: Starting at the beginning of the cursor, the first line that is matched by PAT1 to all rows between the end of the line that was first matched by PAT2;

Can be used together with editing commands for editing operations:
D
Y
C

W/path/to/somefile: Saves the text in the range to the specified file;
R/path/from/somefile: Reads and inserts the text from the specified file into the specified position;

(2) Find
/pattern: Finds all strings that can be matched to the current pattern from the current cursor location to the end of the file;
? Pattern: finds all strings that can be matched to the current pattern from the current cursor position to the file header;
N: Next, same as command direction;
N: Previous, opposite of command direction;

(3) Find and replace
S: Commands in the last-line mode, using format:
s/what to look for/replace with content/modifiers
What to look for: You can use regular expressions;
Replace with: cannot use the next expression, but can be referenced;
If the "What to find" section uses a grouping symbol in a pattern: use a back reference in "Replace with";
Direct reference to find the pattern to match all the text, to use the & symbol;
Modifier:
I: ignoring case;
G: Global substitution means that if a row is matched to multiple times, it is replaced;

You can replace the delimiter with other non-characters commonly used characters:
[Email protected]@@
s###

Example:
%[email protected]\<t\ ([[: Alpha:]]\+\) \>@t\[email protected]
%[email Protected]\<t[[:alpha:]]\+\>@&[email protected]
