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=E2=80=
=99s
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 =E2=80=93 n/p a=
nd
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=E2=80=99d prefer to maintain th=
at
symmetry.
