select/copy content of cck field with one-click

Hi,

There is a module called CCK Extras in Drupal 5 (http://drupal.org/project/cck_extras). I need to do the following in DRUPAL 6.

Text as Textarea: Display a CCK text field as a form element, with selectable, copyable text. Useful for displaying bits of text users will want to copy into another window, like CSS snippets or YouTube embed codes.

Does anyone know what I can use to do this in Drupal 6?

Thanks in advance,
Susan
