This isn't true, as far as I know. Some menus are, but hotkeys have been changed quite a bit. Quite a few menus seem mouse only.
I can't ABABABABABAB to add a bunch of beds to a carpenter anymore, DD doesn't mine.
The hotkey path for placing doors in the steam version is bananas. Still a great game! Hoping there's a mod or a patch that lets me use the classic keys with the new interface eventually though.
