Selecting a range with the mouse is the obvious gesture once clicking selects a line, and it's the only way to get a range without knowing the keybindings. The range has to be anchored where the mouse went down, which the view can't tell us: a click in hunk mode selects a whole block, leaving the view's own range anchor at the block's far end, so a drag from there would grow the selection from the wrong end. So the clicked line is remembered when the click happens, and the drag anchors there. A drag that reaches the edge of the view keeps scrolling, using the same autoscroller the staging view does — mouse capture means the pointer can be dragged past the edge, and there is more diff down there than fits on screen. Unlike the staging view, whose content is a string that is always there in full, this diff loads lazily, so scrolling down has to keep reading it in or the autoscroll would stop at the loaded edge.
