This is the opposite of fixed scrolling and personally, I don't like that. But
this could also be a configurable setting, if wanted.

The left-most character. And I would say that always the whole line is read when
the braille display moves to a new line. So If I am at the beginning of a line
with my 40 cell display, the speech cursor should be on the very first character
and if I navigate right, I think the speech cursor then should be on the
first character shown on the display.

Yes, exactly.

I think so.

Thanks
