Here’s an interesting VimGolf challenge. As they say in the challenge, it’s a simple problem but they’re looking for interesting solutions. The challenge is to turn this
app.config['CHALLENGE_FOLDER'] = SOLUTIONS_FOLDER app.config['SOLUTIONS_FOLDER'] = CHALLENGE_FOLDER
into this
app.config['CHALLENGE_FOLDER'] = CHALLENGE_FOLDER app.config['SOLUTIONS_FOLDER'] = SOLUTIONS_FOLDER
The obvious solution that any Emacs user would think of does the job in 81 keystrokes.
| 【Ctrl+s =】 | cursor to = |
| 【Ctrl+k】 | kill after = |
| 【Ctrl+n】 | down one line |
| 【Ctrl+y】 | insert ␠SOLUTION_FOLDER |
| 【Ctrl+k】 | kill rest of line |
| 【Ctrl+p】 | up one line |
| 【Ctrl+y】 | insert ␠CHALLENGE_FOLDER |
The best Vim solutions also do it in 8.
What I really want to do is something along the lines of
| 【Ctrl+s = Ctrl+s】 | Mark rectangle |
| 【Ctrl+x r k】 | Kill rectangle |
| 【Ctrl+x Ctrl+t】 | Swap lines |
| 【Ctrl+<】 | Beginning of buffer |
| 【Ctrl+x r y】 | Yank rectangle |
that’s 12 keystrokes, 50% more than the obvious solution. If I use CUA Selection Mode (as I wrote about previously) I can do it in 9 with essentially the same method as above. Is there a clever way of doing this or is the obvious solution with 8 keystrokes the best we can do? If you can beat 8 keystrokes—especially if it’s something clever—be sure to leave a comment.
Update: Fuco does it in 6.
Update 2: Fuco shaves off another keystroke to a total of 5. Definitely a heavy weight contender.

1 Using our usual rules of changing the text but not saving the buffer.
