Imanewbie - where are the hotkey assignments?

I read that in the 1.1 or 1.11 patch, that a lot of new hot keys were added, but I can't seem to find a screen that tells me what actions are mapped to what keys? This isn't a game breaker, of course, but if I can't find something as simple as key assignments, it makes me feel like I may be overlooking all sorts of things in the game.

So, where is/are the screen(s) for the key assignments?
