You can still have a "fullscreen editor" environment on a 320 wide display, case in point: the KC85. You could move the cursor around on screen and if there was a command under the cursor, it would be executed: https://floooh.github.io/tiny8bit/kc854.html https://floooh.github.io/tiny8bit/kc854.html Many applications used the same menu system and thus automatically inherited this screen editor functionality. Apart from that, Forth also had a screen editor, you could define a new word, run it, and then move the cursor up over the original definition and modify it without having to retype everything: https://floooh.github.io/tiny8bit/kc854.html?mod=m026&mod_image=kc85/forth.853&input=SWITCH%208%20C1%0AFORTH%0A https://floooh.github.io/tiny8bit/kc854.html?mod=m026&mod_im... ...the builtin KC BASIC on the other didn't have such luxury, most likely because it also needed to run on other home computer systems that didn't have this screen editor capability.
