That seems an internal contradiction: it should be easier to memorize command names than PF key definitions. And "PF keys whose labels (and actions) were context sensitive" (extremely modal) is only possible with a very sophisticated terminal that can re-label keys depending on context (like Mac Pro's touch bar?) Or was there a key legend on screen?
