Maybe Tektronix storage tube displays that didn't erase anything until you cleared the whole screen at once?

Oh, yeah. I heard that Home key was way more important in a few terminals for that reason. (Clear erased from cursors to end of screen?)

Oh interesting, I didn't know that was a thing. Time to break out the termcap file and see which terminals' clear-screen sequence includes a cursor movement as part of it

Oh weird. An emacs-style point-and-mark model with the cursor as one end of the region?

I just like we were still figuring out what cursors were and what powers they had. Reading some Bitsavers IBM manuals is super interesting.

Yeah the whole idea of editing the screen contents with local control keys and then transmitting it back as a block is so foreign now

Even though that was kind of how BASIC program editing worked on the Apple II so I grew up with a vestige of it
