Lengh limited body text

Hello there and thank you for yet another great Drupal Module.
In your description, you mention:
"Length-limited body text with live, javascript-based counter showing characters used and remaining while user enters the body text - no need to hit submit and wait for an error message."
Would it be possible fo you to indicate the code or a snippet so i could use this fonction for other content type?
I am not a programmer and I have been looking for this function for a while now....
Many thanks,
