When you say "by hand" do you mean with a pen and paper rather than typing it out? If so, can you say something more about why?
Mainly I use vim. But yes, sometimes I also use a traditional notepad with a soft ink pen. To avoid myself some screen time, because I'm out of home, or just to make some use of it.
I think the output flow is about the same using pen and paper than using vim, at least for me.
The original "By hand" did mean "without AI help/inspiration".

A technique that I don't know what to call, is the horizontal brace. Like the ASCII 123, but horizontally, to insert something between two words, above or below the line.A handicap of the notebook, is that you can't find historical data/names/dates so easy, or synonyms... but as I iterate a few times over the text after the first draft, those gaps can be fixed latter while typing the text.
