replace-string works with and without a region, when I did exactly
as you told me. But perhaps there is more to regions?

What's that? :)

I got that solved. Now,

replace-string 'Hello all!' 'Dear all,'

works.

The code [1] got somewhat complicated...

DWIM, is that what I'm doing? Why did you say that? I'm to read
the Wikipedia article tonight - never heard of it, but intuitively
I like it.

Some people take pride in memorizing and understanding complex
command, drawing oh's and ah's from the crowd: what wizardry! I
think that's just silly. In a nutshell, this is what my system
looks like:

add_dic () { sudo tar -xvjf $1 -C /usr/share/stardict/dic; }

That's why Captain Picard say "Engage!", and not "Set the
thrusters to blaha blaha, align the ship to etc. etc., then..."

(Perhaps that's unrelated to DWIM.)
