info works without emacs, but some people prefer emacs' info viewer to the console one. The console viewer does have some idiosyncratic keybindings - for example, "n" means "next node at same level", and "}" means "search for next occurrence". "H" will give you a quick overview.
I'm surprised indexes aren't working for you - unfortunately I don't know of any suggestions to fix that.
From some other comments, it sounds like "info" uses emacs at its core? So I suppose I'd have to learn some emacs commands, if that's the case.
