I do...sometimes. Often I'll jot notes for parallelism questions, on which I may have to make a connection between several list items.
My scrapboard might have this on it(she) joined....
, was injured, and was discharged
, was injured, while being discharged
and was injured, and discharged
, injured, and was discharged
, having been injured and discharged
I can more easily see the intended parallelism vs. the faulty parallelism with all the garbage removed.
Other times when I think notes might help:
(1) There are 3 or 4 splits, but I'm not enthusiastic about any of them. I can eliminate choices that have the most "X"s next to them in my notes.
(2) Long underlined section and I want to keep track of not only what I eliminated but
why, just in case I have to reconsider once I reach the end.
