Well, I can't really help you on your XF86Config problem, but I do have a few tips:
1) To exit from man pages, just hit 'q'.
2) If all else fails, CTRL+C is your friend. CTRL+C will close *most* terminal programs.
3) Emacs doesn't really have a menu per se, you have to hit a combination of CTRL+(whatever) key combinations. For example:
Save: CTRL+X then CTRL+S
Quit: CTRL+X then CTRL+C
I haven't used emacs in a while, so I don't know any more combinations than that.
