30 | ;; How to Use: |
31 | ;; M-x mh-rmail to read mail. Type C-h m there for a list of commands. | |
32 | ;; C-u M-x mh-rmail to visit any folder. | |
33 | ;; M-x mh-smail to send mail. From within the mail reader, "m" works, too. | |
b578f267 | 34 | |
a1b4049d BW |
35 | ;; Your .emacs might benefit from these bindings: |
36 | ;; (global-set-key "\C-cr" 'mh-rmail) | |
37 | ;; (global-set-key "\C-xm" 'mh-smail) | |
38 | ;; (global-set-key "\C-x4m" 'mh-smail-other-window) | |
