This question does not have exact answer because you write "not often on any keyboard" which sounds vague. On the other hand, I understand the merit of the question.
I was examining this topic some time ago and based on list of Keyboard scan codes and its programmatic testing I compiled the following

Many of these are legacy keys from computer systems of the past. Their meaning can be sometimes found (example: PA1 key), sometimes not easily.
