This, plus the multiple-cursors package, can save entire minutes off tedious file-renaming operations. (That may not sound like a lot but trust me every second counts when you're just renaming files.)

Heh I've used emacs for years and never knew about this.

I actually don't tend to use emacs as a file manager for whatever reason. I find shell file utility commands along with sed, awk, xargs to be adequate.

wdired was a revelation on what an editor can do with capable and imaginative developers on it.

Emacs mostest problem : too many features unless you spend 5 years in it

I liked that roamer has a similar idea, the name/hash lines seems very straightforward. Also a bit of acme in it where text as a bit of meaning.

Maybe it will give wdired ideas too.

Yes, like 'M-x calc' which gives you a very decent RPN calculator.

oh calc is way more than that. it's a cute CAS. And a nice RPN calc. (which I think is simple-calc-mode actually)

Emacs also has bindat, a nice DSL to create bytes structures (for network packets or FFI)

And that's just the vanilla distribution.. Anyway lisp.

Out of curiosity, why did you capitalise editor?

It's the name of an environment variable that most programs respect when opening an editor.

Ah, fair enough. I wasn't sure it emphasis as part of the whole "editor vs ide" dealio.
