It doesn’t have to be on a computer.
On my keyboard, I use left alt as a layer for vim keys outside of vim, caps lock as ctrl, and right alt as escape. I’ll combine them so I can move forward and backwards a word or delete/backspace a full word.
What kinds of things do you do?
Paper notebooks.
I fully believe we’ve come full circle in that technology was intended to sort out the mess of physical documents, bookkeeping etc, but now is inherently messier by itself and you should go back to pen and paper.
