If you need to comment out lines of text inside VIM, you can try this trick:

(Enter command mode in VIM)
:40,105s/^/#/g

This will insert the # character at the beginning of each line starting from line number 40 to line number 105.

If you cannot see the line numbers, do this:

(Enter command mode in VIM)
:set number

To remove the lines:
:set nonumber

This is quite handy if you need to comment out lines of codes in a script.
