- **Epistemic status:** #seedlings Vi is an open source text editor tool authored by Bill Joy, originally created for the Unix operating system. It became the de facto standard Unix editor until the rise of Emacs after 1984. The single Unix specification specifies Vi, meaning that every single conforming system must have it. ## History ![[Pasted image 20220427082808.png]] Designers of the ADM-3A terminal put the arrow keys on `h,j,k,l` forcing modality. Bill Joy was utilizing it over a 300 baud connection, making each keystroke take seconds to register on the terminal. This pushed Bill Joy to produce a text editor that he could type ahead increasing his productivity. --- ## References - “Vi.” In _Wikipedia_, April 26, 2022. <https://en.wikipedia.org/w/index.php?title=Vi&oldid=1084737570>.
