When you open the vi text editor, you start in “command” mode, which allows you to use various commands for deleting text, regular expressions, jumping to lines, inserting lines, and so forth. Anyway, to actually write stuff, you’ve got to go into one of the various edit modes. This requires pressing one of a few various keys (for example, i for insert, a for append, R for replace, and so on).
And here, we see me continuously forgetting to go into insert mode.
