Toggle 1st and 3rd person by prssing Z. I still don't know where "history" is. Is it when you start a new game or what? I just always click on clan & gender.
And in general, all the commands can be seen by looking through the options from the ESC-screen.
The character histories were part of what the game developers were planning on including but ran out of time to get them finished. The unofficial patches (by
Wesp) have these included. They are interesting to read and some can have a real effect on your game, though most won't make a big difference. There are different history choices depending on your character's sex and clan, although some are shared.

I started playing this game again the end of this weekend. This time I'm a Brujah, which so far hasn't seemed much different, but I haven't made it downtown yet to their base, although that'll happen tonight.
I wanted to warn that I ended up having to reinstall the game after using Wesp's latest unofficial patch (version 6.2) because the "grab object" action wasn't being made available. What I'm talking about is picking up boxes to move them around or cans/bottles to toss to make noise. The hand icon never appears and pressing E (action) had no effect. His previous version (6.1) works fine for me, which is what I'm using right now.
