- Those are trim positions to prevent chain rub on the front derailleur when in crosschained gear combos. See https://www.youtube. com/watch?v=CR8jyNgoS0U for a good little visualization (remove the space in the URL - youtube links are really weird on this forum.)
- The chain getting stuck between the front derailleur and the chainring is how shifts happen - the chain is forced into the big chainring which picks it up and deposits it onto the teeth. Of course, this only happens when pedaling - nothing will happen if the crank isn't rotating.
