If you're writing a post that you're publishing to WordPress (or as type=html from a named outline) and want to wrap blockquotes around the complete text of a headline, add this to your Scripts menu:
op.setLineText ("<blockquote>" + op.getLineText () + "</blockquote>");
This script will transform
Just put your cursor on the headline and choose the script. Highlighting a portion of the text won't do anything -- the entire headline is always surrounded by the tags.
