Simply showing the previous > page (the equivalent of M-v) adds no value. If you want to jump back to the previous message, you can press `p'. (And M-v is a chord whereas DEL and p are a simple keystroke, so it’s arguably maximally convenient to duplicate a chord command on a single key rather than duplicating a single key on another single key.) The way I look at it, notmuch has two sets of movement keys – n/p and SPC/DEL. The former moves by messages, and the latter by screenfuls (with the added complication that the screenful movement commands also stop at intervening message boundaries). I’d prefer to maintain that symmetry. -- Aaron Ecay
