Short codes for email campaigns

I am creating an email campaign with out using the builder and I am looking for a list of short codes that I can include. I know that I can use the following for unsubscribe:

Code:
{unsubscribe_url}

And if I type {leadform... I get a list of contact fields but is there a way to include a link to the web preview of the email and to forward the email on?

Thanks
