The article mentions this being on some activation like tab or similar like bash uses. Automatic completion could work with two levels of highlighting. Example with []/{} showing active/suggestive: "[G]" <- Typed "[G]{oo}" <- Displayed in input, with Google/GoodReads as options "[Goo]" <- Tab Pressed "[GoodReads"] <- R Pressed "[Google"] <- g pressed "[Gx]" <- Any other character x Then things like Chrome's url bar will fill in the complete first suggestion with a way to clear it which gives UX like: "[G]" <- Typed "[G]{oogle}" <- Displayed "[G]" <- Backspace pressed
