I'm still trying to get the feel of the game again and have 2 questions.

1. How can I remap my mouse. I tried to go into configuration but it doesn't do anything. I want to map my mouse button 4 to move forward. Someone said I could but can't figure it out?

2. Is there an auto attack function? I mean I can't use my attack to start off with because I don't have any TP so is there a key that I can tab to select the target (which I know how to do) and then hit ? to start auto attack?

3. Is there a key for going into and out of passive mode?

thanks.
