That's surely an alternative, but it already works for me, because I
have: whichwrap=<,>,[,]

(It'll be '>' which is facilitating it, IIUC.)

That seems fine. If there is anyone who cannot tolerate cursor wrapping,
but absolutely needs the shorter and (IME) more easily remembered
zM<right-arrow> form, then your option is the way forward. ISTM that
Vim is admirably (and _almost_ perfectly) configurable.

the need for leading "\v", e.g. with a config selection instead, then
Vim is Purrrrfect! :-)
