Flight manual for vim

I carry around a (very humble) collection of fzf utilities, where I intend to leverage a tacit promise of Vim: I can edit content, right there in the terminal, between two commands, and be done earlier than a corporate IDE would be flashing its splash screen¹.

But let's put aside the speed: I mean to talk about the availability and convenience.

With moreutils, this elevator pitch needs to be challenged: between two commands? Laughable. The adept functional programmer in me should have sniffed it out some time ago: I can use Vim like I use sed.
