it should be on super-space. and super-enter creates an new terminal.

I saw that on the web page. All I needed to know, minus how to get the bar on the top. The Action|Keybinding menu that comes up on first launch is simply too tall to fit on my laptop screen; the most important section Launch is off screen if I don't close several of the others. All in all, though, I'm very impressed with it.

Glad that your enjoying it. Just add these lines to ~/.config/i3/config and reset. That should get the bar on the top.

  # Start i3bar to display a workspace bar
  bar {
    position top
    status_command i3status
  }
