I downloaded the dictionary from DigitalCat also. I took Stenograph. (Some of this was so easy, I was sure I was doing it wrong).
It got complicated. I'm still trying to build my speed. I'm trying to get a good dictionary. You can't really build speed - and believe it - when you look at the transcript and have a lot of unedits.
My solution is: To work on just my dictionary, I have downloaded a deposition transcript off the Internet. I happened to get Monica Lewinsky's deposition. I put it in my favorites. I write clean for a Q and A. Look at it. Then add to my dictionary or fix my writing.
