So, hold control, tap U, release control, tap 1 and then 0, hold
control, tap F, and then release control?

Close, but not quite what I was thinking of.
I was thinking more like you have some text such as
case x of
5 -> return [(1, 4), (2, 3)]
6 -> return [(1, 5), (2, 4), (3, 3)]
7 -> return [(1, 6), (2, 5), (3, 4)]
and you suddenly decide you need to change that to
case x of
5 -> return $ Just [(1, 4), (2, 3)]
6 -> return $ Just [(1, 5), (2, 4), (3, 3)]
7 -> return $ Just [(1, 6), (2, 5), (3, 4)]
It's kinda tedious to do this by hand. (Depending on just how many times
you need to do it, obviously...)

Fair enough. I'm sure you can change this too, mind.

Um, I think it's just the extra behaviour-modifier key of your choice.

I'm no expert, but I strongly suspect that there's a setting for everything,
including mountain-moving!

Yup, well, you can't make things powerful *and* easy. :-P

Ha, you only get 1/2.

If you do the following keystrokes:
C-home // beginning-of-buffer
down // next-line
C-k // kill-line
C-y // yank
down // next-line
C-x ( // start-kbd-macro
down // next-line
C-e // move-end-of-line
C-y // yank
C-x ) // kmacro-end-macro
C-u // universal-argument
9 // 9
C-x e // kmacro-end-and-call-macro
- while editing this text:
This is the first line in buffer.
This is the text to be appended.
Line A.
Line B.
Line C.
Line D.
Line E.
Line F.
Line G.
Line H.
Line I.
Line J.
- you get this:
This is the first line in buffer.
This is the text to be appended.
Line A.This is the text to be appended.
Line B.This is the text to be appended.
Line C.This is the text to be appended.
Line D.This is the text to be appended.
Line E.This is the text to be appended.
Line F.This is the text to be appended.
Line G.This is the text to be appended.
Line H.This is the text to be appended.
Line I.This is the text to be appended.
Line J.This is the text to be appended.

Couldn't you just mark the region
- and then do a search for "return" and replace with "return $ Just" ?

In all editors I've used (including POV - try it!), you would hold down the
Alt key, then click and drag from the top [ to the bottom [ to mark the
region you want to type into. Then when you type it gets inserted on every
line in that region.

It's intelligent wrt your code in a way that no other editor I know is.

Well, we'll see.

I'm not so sure. ;-)

Well, I guess... how many other editors are programmable enough to
implement SkyNet? ;-)
