I created a custom way of selecting/deselecting, and it no longer works in 2.8.
I had r-click drag to make the selection box, letting go of r-click to select additively. And I could press left click while the box is active in order to deselect. It was quite efficient to remove the use of shift and alt for selection.
Here's an image of my old settings plus where I think the new gestures are meant to be put (except it does not work).
So, how can I recreate my old selection behavior, using 2.8's preferences?
