I think this is confusing. I would expect SHIFT-DRAG starting in an open 
area to ADD to the selected set, not reset it, which is the unmodified 
gesture. Most graphics apps work like that. If the density is so great 
that you can't decide whether you're selecting and area or dragging, I 
would suggest that you don't realistically know what you would select 
anyway and that you would have to zoom in to get it right anyway.
