It is really not very helpful. First there is a banner across the TT menu which makes it very hard to follow the rapid clicks being used. Second the video goes too fast (particularly since some of the areas being clicked are partially hidden by the banner) and I see no way to slow it down. Third it does not start with a blank page and it seems impossible to get rid of all existing content boxes. I would like to know how to do this as well. If the two issues I mentioned above were addressed, I think I would find it to be a useful tool. As it is it is just frustrating.
