This is a spectacular feature request, especially as someone who works back and forth between Illustrator and CAD/3D Modeling (Rhino). I would love the option to use Shift+Click for add to selection and Ctrl+Click to remove from selection, or even have the option to use the direct selection tool in addition only or subtraction only mode similar to the rectangular marque tool in Photoshop, although this would be more cumbersome.
