You don't need a sophisticated terminal to have context-dependent definitions 
of a PFK; all that you need are macros that test the context. BTDT,GTTS (no 
scars, just the tee shirt)

Of course, if you want the labeling on the key to change, that's harder.

??? 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?
