The Legacy Of The ADM-3A Terminal
The development of the vi editor started in 1976. The very same year the ADM-3A terminal shipped.
This text editor famously uses HJKL to move around a file. Bill Joy chose those keys because of the ADM-3A terminal’s keyboard. Notice the directional arrows on those keys. Forty two years later, a variety of softwares, like Vim, still use HJKL.
Additionally, did you notice the tilde on the Home key? This is why the ~ character represents the home directory in Unix-like operating systems.Posted on 2018-01-22 #vi #history
