puts "Wisdom:

Even if you generally like vim,
it's good to learn the emacs basics,
because emacs is everywhere
and is often the default
(especially on macs)

emacs bindings cheat sheat:
C-a (go to stArt of line)
C-e (go to End of line)
C-k (delete to end of line (Kill))
C-p (go to Previous line)
C-n (go to Next line)
C-b (go Back a character) (note: this conflicts with the tmux prefix :( )
C-f (go Forward a character)

using emacs as an editor cheat sheet:
emacs . (open emacs)
C-x C-c (quit emacs)
C-x C-f (find a file)
C-_ (undo)
