Yes, the 19th century technique for writing faster.
My grandmother was a practitioner of the art (I believe she may have done some
stenography at NYU in the immediate post-war years).
The only lesson that I retained from her was “Steven, it’s about writing in
circles.” She took a needle-sharp pencil and lightly traced the Gregg shorthand
ovals that define most of the strokes. Intersecting, they looked like she was
drawing the guide-shapes to illustrate a portrait. She then scribbled out a few
words and I thought that was incredibly cool.
In honor of her, I decided I wanted to learn this skill too.
