Poka-Yoke

I love this. Poka-Yoke is a Japanese phrase that originated at Toyota to describe designs intended to be mistake-proof; e.g., an ignition key that can’t be removed unless the car is in Park. Via Mike McCracken, suggesting a logical reason why Apple Mail’s keyboard shortcut for Send (Shift-Command-D) is relatively out of the way.
