thanks for all these comments. I will add this information. It will be included in the next upload. Here just some statements from my side:

1) Thats right. But the 1000S has an additional lever on the body for this purpose (I dont know why...)
2) that text list is older and will be removed or updated later
8) Thats valuable information. I will add a footnote for that to the list

Thanks again. I already know that Butkus-site. Thats also where I got a lot of information from.
