define-key versus evil-define-key

[Nikolai Weibull]

Hi!

What’s the preferred way of adding keys to a given mode’s map?

Is

(define-key evil-motion-state-local-map "\C-b"
'calendar-scroll-right-three-months)

or

(evil-define-key 'motion calendar-mode-map "\C-b"
'calendar-scroll-right-three-months)

preferable?

(From an ease-of-use perspective, the second is better, as it allows
you to easily map more keys, but I’m wondering from a “the right way
to do it” perspective.)
