Just a quick question. I'd like to use the text editor program that Don uses in this video - he called it Vi. I am running MacOS Big Sur (11.1) and when I open the terminal and type in Vi, I can't seem to use it in the same way he does... Can anyone give me a few pointers to get this up and running on my Mac? Or point me in the direction of a walkthrough online? I have had a quick look, but can't seem to see one....?
Any help would be great!
