: Set Nu
: n1,n2s/^/#/g (^ Indicates the beginning of the line)
Delete a comment
: n1,n2s/#//g (delete all lines starting with # Delete including # in line)
: n1,n2s/^#//g (delete only # at the beginning of the line)

Special: Add two characters//
: n1,n2s/^/\/\//g header plus//characters


Replacement:
