I would like to see 2 keyboard shortcuts. One that snaps and sequentially zooms in on the right of a range selection boundary every time its pushed, and another one that zooms in on the left boundary of the range section at the same zoom level. This way a person can jump from one side to the other of the selection without needing to zoom in and out first. And, whatever level of zoom settled on initially on one side is the same level of zoom on the other when hitting the opposite keyboard short cut. This would dramatically speed up precision edits!
