Ok, I can answer the last question by myself: using event.detail =
DND.DROP_NONE.
But Shift is not working for me...

Well, Shift is the same as no modifier pressed (DND.DROP_MOVE), so there
is no change. So, no, Shift can not be detected.

Setting operation to DND.DROP_NONE during dropAccept prevents the drop
event. Does that help?
