Search and Replace Scanner - works on all nodes text content.

Code

function scanner_confirm_form() {

  //using set_html_head because it seems unecessary to load a separate css

  // file for just one declaration:

  //you can override the styles by declaring with something "higher up"

  // the chain, like:  #wrapper #scanner-confirm-form .scanner-buttons .scanner-button-msg {...}
  drupal_set_html_head('
    <style type="text/css">
      #scanner-confirm-form .scanner-buttons .scanner-button-msg {

  //javascript to prevent further clicks on confirmation button after it's clicked once.

  //unfortunately we can't just use css disable to disable the button because then

  // the op values aren't sent to drupal correctly.
