That´s not really true for 3d software. In fact every 3d program I ever used had the “left click – hold and drag” function for border / rectangular selection. – 3dsmax, Rhino, Fusion360, Autocad… just to name a few. For some the drag object is working on top of that when hovering above a selected object and dragging to move. And just clicking once on an empty area deselects all. At least for me this seems like the standard convention for selection. This is not really possible with the existing Blender shortcuts and I guess that would be too hard to implement into BforArtists?
