[rt-users] Script Codes

[Sysadmin]

Is there a cheatsheet of RT script codes? and/or fieldcodes

Specifically,  I'm looking to insert the "Real Name" of the user 
assigned to a ticket. (currently inserts username)

also I'd like to generate the Email notification when the ticket is 
first assigned from "nobody" to "somebody"
I'm currently using the owner change script. which sorta works, but does 
not allow me to use owner change as it was intended.

Thanks,
