The edit function will open the editor that is defined in the options. While in RStudio, this is a specially designed pop-up window with buttons to save and cancel, in the command line interface (CLI) this might be vi. The heydays of this fantastic editor are over and you might never have seen it before. It is not really possible to use vi without reading the manual (e.g. via the man vi command on the OS CLI or an online tutorial). To get out of vi, type: [ESC]:q![ENTER]. Note that we show the name of a key within square brackets and that all the other strings are just one keystroke each.
