Pseudo-code that looks like real code but isn't -
run!!!

;; syntax for `if' with single-form branches

(if (eq major-mode 'mu4e-headers-mode) (do-something)
  (do-something-else) )

;; ditto multiple-form branches

(if (eq major-mode 'mu4e-headers-mode)
  (progn
    (do-something-step-1)
    (do-something-step-2) )
  (progn
    (else-do-this-step-1)
    ;; ...
    (else-do-this-step-n) ))

;; syntax for when

(when condition
   (do-this)
   (and-this)
   (including-this) )

;; group major modes

(unless (member major-mode '(makefile-gmake-mode
                             makefile-mode) ) ; exceptions
    (untabify (point-min) (point-max)))
