Emacs

Emacs is ancient bit of software that is the fanciest text editor around. It’s like a shark in that it hasn’t evolved in years but is perfectly suited to what it does. I use it a lot, mainly for Org-Mode.

I wouldn’t necessarily recommend it to anyone unless you are prepared for a fairly steep learning curve. Because it’s a thirty year old piece of software, it has interesting quirks that are difficult to learn. You may find you fall into the System-Maintenance-Trap when the Tools-Dont-Matter as much as the words. I took a long time messing around with irrelevant setups before I focused on what matters.
