Database of Search / Go box commands?

I'm fairly new to Logos (less than a year) and I still feel like I don't know half of what this amazing program can do. The other day, while searching the forums, I found out about the FSD command. That was great. But how would anyone know about that without stumbling upon it in a forum post? So my question is, where can I find - or is there - a list of all the commands that can be entered in search or go box fields?

Thanks.
