How to annotate multiple lines in vim

Using Find-and-replace methods

In Linux, the starting mark for each line of text is ^, the ending sign is $, so use vim to search for ^ and replace with ^ #即可.

: 10,20s/^/#/g

Indicates that 10-20 rows are added to the annotation, and the same uncomment as:

: 10,20s/#//g

Using the Record Macro feature

Move the cursor to the first line of->esc->qa->i->#->esc->j->q you want to comment out

Qa:q is the beginning of the recording, followed by the name, here is a, also can be other

The last q indicates an end recording

@a will repeat the A just recorded

10@a will repeat it 10 times.

Another way is to block operations:

CTRL + V, select row, I (capital i), #, ESC
