Question about mp3 filename creation

I’m using Nero 7 to rip some of my CDs to mp3s, and I’m utilizing the “User Defined” template to auto-generate the file names. The current template is “%A %N %T %E”, which generates the (A)rtist, track (N)umber, (T)itle of song, and (E)xtension.

Problem is, I’d like to auto-generate the album title as well, so I don’t have to change the filename manually, but I don’t know the code for that. Can someone please direct me to a glossary of how these auto-generation codes work? Thanks in advance.
