I learned a lot of tricks from being an auditor stuck in out of the way rooms, closets, etc. I actually did an audit in a bank vault with the accounting books, workpapers I was filling out, an adding machine, 2 chairs and a metal typing table. Another time I performed an audit on the stage of a gymnasium stage while summer camp was going on; very noisy.
I can type one handed, although a little slowly, write a bit with my left hand and read upside down material if it is printed or the cursive very clear.
