The WordPress 'new post' bookmarklet lets you highlight some text on a page, run the bookmarklet and redirects you to your admin new posts page with the title prefilled with the title of the page you were on and the content prefilled with a link to the page you were on and the text you had highlighted. However, the default layout isn't the way I like to do quote posts, so I had a poke around to find out how to change it.

In the file wp-admin/admin-functions.php there is a function get_default_post_to_edit(). Midway through the function the variable $post_content is set with an HTML snippet. Edit this snippet to how you would like quotes to be displayed.

I wonder what The Right Way to do this is.
