Chris Maiorana has an interesting video on using Emacs to level up on your writing. He was inspired by Jordan Peterson’s writing application essay.app. Maiorana realized that essay was pretty much like Org-mode except that it has a feature missing from Org: you can select a sentence and have it appear in a second window where you can write various versions of it and select the one you like the best. After selecting your favorite, that version is exported back to the text in the original window.
Peterson claims and Maiorana agrees that this method in effective in writing the best possible sentence. Org-mode doesn’t support this, of course, but as Maiorana demonstrates, it’s pretty easy to implement. Maiorana isn’t a programmer so his code is pretty simple but works well.
When he described the problem, my first thought was to use an indirect buffer. One of the commenters, Leslie Russell, had the same thought and came up with a slightly better implementation. It’s still pretty elementary and easy to follow. If you’re interested in something like this, grab Russell’s code (use the second version). You can just paste it into your init.el and give it a try.
I haven’t used this method but it’s certainly true that the best way to improve a piece of writing to try rewriting it. This code makes it easy to do that in sentence sized bites.
