Quick Question: What do my spells do?

[Nofienet]

Hello, everyone. I apologize for the very beginner question, but, either because of scant documentation or my own incompetence, I have not been able to find a straight answer for this even after hours of searching through wikis and video tutorials.

To cut to chase: how do I find out what a spell does in-game without looking up a wiki? I've read in forums for the base Everquest game that one need simply right-click and hold on a spell, but all that gives me is the casting time and mana cost. Am I missing something, or is the information intentionally obfuscated to encourage learning through experimentation?

Additionally, in the name of teaching how to fish vs. simply giving a fish, are there any resources that you would recommend I seek out to help me play the game? The Project 1999 wiki has a lot of useful information, but it doesn't seem to give me the tools I need to organically experience the game the game simply through play.
