+	"Rmail Mode is used by \\[rmail] for editing Rmail files.
+All normal editing commands are turned off.
+Instead, these commands are available (additions from ht's mail-extras.el
+indicated by *:
+.	Move point to front of this message (same as \\[beginning-of-buffer]).
+SPC	Scroll to next screen of this message.
+DEL	Scroll to previous screen of this message.
+n	Move to Next non-deleted message.
+p	Move to Previous non-deleted message.
+M-n	Move to Next message whether deleted or not.
+M-p	Move to Previous message whether deleted or not.
+>	Move to the last message in Rmail file.
+j	Jump to message specified by numeric position in file.
+M-s	Search for string and show message it is found in.
+d	Delete this message, move to next nondeleted.
+C-d	Delete this message, move to previous nondeleted.
+u	Undelete message.  Tries current message, then earlier messages
+	till a deleted message is found.
+e	Expunge deleted messages.
+s	Expunge and save the file.
+q       Quit Rmail: expunge, save, then switch to another buffer.
+C-x C-s Save without expunging.
+g	Move new mail from system spool directory or mbox into this file.
+m	Mail a message (same as \\[mail-other-window]).
+c	Continue composing outgoing message started before.
+r	Reply to this message.  Like m but initializes some fields.
+R	* Like r, but reply to originator only.
+f	Forward this message to another user.
+F	* like f, but assumes message is \"failed mail\" for re-sending
+o       Output this message to an Rmail file (append it).
+C-o	Output this message to a Unix-format mail file (append it).
+M	* Output this message to a file,
+	  in format determined by extension (babyl for RMAIL/msg for Unix).
+B	* Write the body of the message to a file, leaving a pointer
+H	* Print the message (same as \\<global-map>\\[print-buffer]).\\<rmail-mode-map>
+i	Input Rmail file.  Run Rmail on that file.
+a	Add label to message.  It will be displayed in the mode line.
+k	Kill label.  Remove a label from current message.
+C-M-n   Move to Next message with specified label
+(label defaults to last one specified).
+Standard labels: filed, unseen, answered, forwarded, deleted.
+Any other label is present only if you add it with `a'.
+C-M-p   Move to Previous message with specified label
+h, C-M-h Show headers buffer, with a one line summary of each message.
+l, C-M-l Like h only just messages with particular label(s) are summarized.
+C-M-r   Like h only just messages with particular recipient(s) are summarized.
+t	Toggle header, show Rmail header if unformatted or vice versa.
+w	Edit the current message.  C-c C-c to return to Rmail.
+W	* Edit the subject field.  C-c C-c to move the message to the Diary.
+D	* Update the Diary.
+Messages for the diary (see also \\[describe-mode] in rmail-summary mode
+or \\[describe-function] rmail-summary-mode) should have a subject field

+A subset of the Rmail mode commands are supported in this mode.

+u	Undelete this or previous deleted message.
+q	Quit Rmail.

+r	* Same as r in rmail window.  Reply to current message.
+R	* Same as R in rmail window. Reply to current message, originator only.
