I don't really agree. In and of itself the existence of keystrokes doesn't make the UI efficient. There is still a ton of cognative dissonance and unnecessary friction in DF. Keystrokes that work in one place don't work (or worse, don't work the same way) in another, menu options that are very similar are ordered differently in different places etc. If you learn how to work one aspect of UI (say the millitary menus) you can't transfer that knowledge to working another (say the minecart UX) most of the time. Except sometimes you can, which makes it even more confusing.
