The Shortcode AddOn has a new shortcode – pslug. You can use this shortcode to specify the post “slug”
[pslug slug="my awesome slug"]
This will set the slug for the post to “my-awesome-slug”. This lets you have a slug that is different from the title/subject which is the default.
Note that WordPress will “sanitize” the slug to remove characters that would be invalid in an URL. Also slugs have to be unique so if you use the same one WordPress will append a number to the slug to make it unique, e.g. “my-awesome-slug2”
