ex Commands
ex syntax
ex commands in the vi follow this general form:
: Address command
Which means:
Execute command on specific lines obtained from the address part of the general form.
If address is omitted, current line is used. Keep in mind that the ex is a line-based editor; so all
actions are line based.

ƒ $ -- last line of file
ƒ x-n -- n lines before line x
ƒ x+n -- n lines after line x
