Keyboard Shortcuts

Recently I saw a post about new keyboard shortcut features.  For example, the space bar can be used to flip a flashcard; the 5 key can be used to indicate Easy, etc.  I'd like to look at all of these shortcuts.  Where are these shortcuts summarized?

Douglas: the post was titled "Hotkeys are Here" under the Rocket Languages Blog. I think this might take you there:
