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. -- Shmuel (Seymour J.)

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? -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
