Hello,
I would like to know if the following symbols from 1-A to 4-A are still in usage or if they are replaced by 1-B to 4-B?
In 5, how do I know if the hand rotates by 90 degrees or 180 degrees?
In 6, does the sign Forward Under Under has a small backward movement?
In 7, I do not understand the Forward-over-Under symbol. What is the sequence of direction changes?
Thanks
André Lemyre
