Welcome back to emacs rocks!

In this episode we'll take another look at the vimgolf challenge in episode two.

These two emacs enthusiasts twittered me last night

with an even better solution to the problem

let's take a look at what they did

okay, I'll just run through it first

wow

that was ten keystrokes - it's almost like magic

the trick being used to shave off another two keystrokes

from last nights solution was transpose-lines

let's take a look at transpose-char first

if I typo like this, I can go back and switch

did you see it? switch!

but another way of thinking about transpose

is that you're actually moving the char forward

so that's what's being done with transpose-lines

ctrl-x t, and I move typo down

so that's what they're doing

I start ctrl-x t, ctrl-x t

and use that to move the first line down

okay, I'll walk through it

macro, 9x transpose-line

backspace, tab, back to the top

done with the macro, 9x repeat macro

amazing

so, best solution in vim: 17

last night: 12

today: 10 keystrokes

so thanks to Bodil and Christian for an awesome solution
