abstract ;;Quote: fast, minimalist UI for textual applications; editing, scrolling, dedicated mouse buttons, no icons, no pop-up menu; even shell procedures can use the graphical UI; based on Unix file operations and Oberon

268 ;;Quote: rules for a minimalist UI -- no wasted actions, no retyping, automation, defaults; smallest actions do the most useful things; no pop-up menus, no keyboard necessary

268 ;;Quote: typically two columns of vertical overlapping windows; windows have a tag line and a text body

270 ;;Quote: all text is a potential command or argument; e.g., 'Open' a file name in the window's directory by clicking the left and middle buttons

271 ;;Quote: pure, point-and-click interface using text windows and tools; e.g., read mail, debug, and respond without using keyboard
