People can try the emulator.¹ Key to understanding is that GUI operations were two-handed, descending directly from NLS (people have all seen the ‘mother of all demos’², right?). Right hand on the mouse, left hand on the left function key cluster³ — one of the Star papers is explicit that the left cluster was a direct substitution for the NLS/Alto chord set. A very noticeable difference from the familiar Lisa lineage is Move and Copy vs Cut and Paste — there was no clipboard. (Here I think Star got it right and Tesler got it wrong: the condition of the clipboard containing invisible fragile state is a mode, and a worse one than move-in-progress.) ¹ https://github.com/livingcomputermuseum/Darkstar https://github.com/livingcomputermuseum/Darkstar ² https://dougengelbart.org/content/view/209/ https://dougengelbart.org/content/view/209/ ³ https://digibarn.com/friends/curbow/star/keyboard/ https://digibarn.com/friends/curbow/star/keyboard/
