We would like to bind prefix-arg RET in search view to "pick show this
thread" (i.e. notmuch-pick-from-search-thread). It is not easy to do
this cleanly from contrib so I have been using M-RET instead.
Temporarily remove this functionality in preparation for entering
mainline and binding to prefix-arg RET.
;; Set up key bindings from the rest of notmuch.
(define-key notmuch-common-keymap "z" 'notmuch-pick)
(define-key notmuch-search-mode-map "Z" 'notmuch-pick-from-search-current-query)
-(define-key notmuch-search-mode-map (kbd "M-RET") 'notmuch-pick-from-search-thread)
(define-key notmuch-show-mode-map "Z" 'notmuch-pick-from-show-current-query)
(message "Initialised notmuch-pick")
