One thing I noticed in the film is that while it's very clear all the ortho-alphabet writers were using finger writing, it appeared that the shorthand writer was not using her fingers at all -- definitely using her shoulder muscles.
Does anybody use their shoulder muscles to write? I can't remember whether the author of the "Penmanship" exercises article wrote specifically about finger drawing or using the whole arm, but I believe that is what Dr Gregg was talking about when he said one had to *write* Gregg rather than *draw* it.
Who uses just fingers to write (either long or shorthand)? Who uses whole arm?
Thoughts? Opinions? Experiences?
