+
+Mail Mode
+=========
+
+ The major mode used in the `*mail*' buffer is Mail mode. Mail mode
+is similar to Text mode, but several commands are provided on the `C-c'
+prefix. These commands all deal specifically with editing or sending
+the message.
+
+`C-c C-s'
+ Send the message, and leave the `*mail*' buffer selected
+ (`mail-send').
+
+`C-c C-c'
+ Send the message, and select some other buffer
+ (`mail-send-and-exit').
+
+`C-c C-f C-t'
+ Move to the `To' header field, creating one if there is none
+ (`mail-to').
+
+`C-c C-f C-s'
+ Move to the `Subject' header field, creating one if there is none
+ (`mail-subject').
+
+`C-c C-f C-c'
+ Move to the `CC' header field, creating one if there is none
+ (`mail-cc').
+
+`C-c C-w'
+ Insert the file `~/.signature' at the end of the message text
+ (`mail-signature').
+
+`C-c C-y'
+ Yank the selected message (`mail-yank-original').
+
+`C-c C-q'
+ Fill all paragraphs of yanked old messages, each individually
+ (`mail-fill-yanked-message').
+
+`<button3>'
+ Pops up a menu of useful mail-mode commands.
+
+ There are two ways to send a message. `C-c C-c'
+(`mail-send-and-exit') is the usual way to send the message. It sends
+the message and then deletes the window (if there is another window) or
+switches to another buffer. It puts the `*mail*' buffer at the lowest
+priority for automatic reselection, since you are finished with using
+it. `C-c C-s' (`mail-send') sends the message and marks the `*mail*'
+buffer unmodified, but leaves that buffer selected so that you can
+modify the message (perhaps with new recipients) and send it again.
+
+ Mail mode provides some other special commands that are useful for
+editing the headers and text of the message before you send it. There
+are three commands defined to move point to particular header fields,
+all based on the prefix `C-c C-f' (`C-f' is for "field"). They are
+`C-c C-f C-t' (`mail-to') to move to the `To' field, `C-c C-f C-s'
+(`mail-subject') for the `Subject' field, and `C-c C-f C-c' (`mail-cc')
+for the `CC' field. These fields have special motion commands because
+they are edited most frequently.
+
+ `C-c C-w' (`mail-signature') adds a standard piece of text at the
+end of the message to say more about who you are. The text comes from
+the file `.signature' in your home directory.
+
+ When you use an Rmail command to send mail from the Rmail mail
+reader, you can use `C-c C-y' `mail-yank-original' inside the `*mail*'
+buffer to insert the text of the message you are replying to. Normally
+Rmail indents each line of that message four spaces and eliminates most
+header fields. A numeric argument specifies the number of spaces to
+indent. An argument of just `C-u' says not to indent at all and not to
+eliminate anything. `C-c C-y' always uses the current message from the
+`RMAIL' buffer, so you can insert several old messages by selecting one
+in `RMAIL', switching to `*mail*' and yanking it, then switching back
+to `RMAIL' to select another.
+
+ After using `C-c C-y', you can use the command `C-c C-q'
+(`mail-fill-yanked-message') to fill the paragraphs of the yanked old
+message or messages. One use of `C-c C-q' fills all such paragraphs,
+each one separately.
+
+ Clicking the right mouse button in a mail buffer pops up a menu of
+the above commands, for easy access.
+
+ Turning on Mail mode (which `C-x m' does automatically) calls the
+value of `text-mode-hook', if it is not void or `nil', and then calls
+the value of `mail-mode-hook' if that is not void or `nil'.

+
+Reading Mail
+************
+
+ XEmacs provides three separate mail-reading packages. Each one
+comes with its own manual, which is included standard with the XEmacs
+distribution.
+
+ The recommended mail-reading package for new users is VM. VM works
+with standard Unix-mail-format folders and was designed as a replacement
+for the older Rmail.
+
+ XEmacs also provides a sophisticated and comfortable front-end to the
+MH mail-processing system, called `mh-e'. Unlike in other mail
+programs, folders in MH are stored as file-system directories, with
+each message occupying one (numbered) file. This facilitates working
+with mail using shell commands, and many other features of MH are also
+designed to integrate well with the shell and with shell scripts. Keep
+in mind, however, that in order to use mh-e you must have the MH
+mail-processing system installed on your computer.
+
+ Finally, XEmacs provides the Rmail package. Rmail is (currently) the
+only mail reading package distributed with FSF GNU Emacs, and is
+powerful in its own right. However, it stores mail folders in a special
+format called `Babyl', that is incompatible with all other
+frequently-used mail programs. A utility program is provided for
+converting Babyl folders to standard Unix-mail format; however, unless
+you already have mail in Babyl-format folders, you should consider
+using VM or mh-e instead. (If at times you have to use FSF Emacs, it is
+not hard to obtain and install VM for that editor.)

+Calendar Mode and the Diary
+===========================
+
+ Emacs provides the functions of a desk calendar, with a diary of
+planned or past events. To enter the calendar, type `M-x calendar';
+this displays a three-month calendar centered on the current month, with
+point on the current date. With a numeric argument, as in `C-u M-x
+calendar', it prompts you for the month and year to be the center of the
+three-month calendar. The calendar uses its own buffer, whose major
+mode is Calendar mode.
+
+ `Button2' in the calendar brings up a menu of operations on a
+particular date; `Buttons3' brings up a menu of commonly used calendar
+features that are independent of any particular date. To exit the
+calendar, type `q'. *Note Customizing the Calendar and Diary:

+Movement in the Calendar
+------------------------
+
+ Calendar mode lets you move through the calendar in logical units of
+time such as days, weeks, months, and years. If you move outside the
+three months originally displayed, the calendar display "scrolls"
+automatically through time to make the selected date visible. Moving to
+a date lets you view its holidays or diary entries, or convert it to
+other calendars; moving longer time periods is also useful simply to
+scroll the calendar.

+
+Motion by Integral Days, Weeks, Months, Years
+.............................................
+
+ The commands for movement in the calendar buffer parallel the
+commands for movement in text. You can move forward and backward by
+days, weeks, months, and years.
+
+`C-f'
+ Move point one day forward (`calendar-forward-day').
+
+`C-b'
+ Move point one day backward (`calendar-backward-day').
+
+`C-n'
+ Move point one week forward (`calendar-forward-week').
+
+`C-p'
+ Move point one week backward (`calendar-backward-week').
+
+`M-}'
+ Move point one month forward (`calendar-forward-month').
+
+`M-{'
+ Move point one month backward (`calendar-backward-month').
+
+`C-x ]'
+ Move point one year forward (`calendar-forward-year').
+
+`C-x ['
+ Move point one year backward (`calendar-backward-year').
+
+ The day and week commands are natural analogues of the usual Emacs
+commands for moving by characters and by lines. Just as `C-n' usually
+moves to the same column in the following line, in Calendar mode it
+moves to the same day in the following week. And `C-p' moves to the
+same day in the previous week.
+
+ The arrow keys are equivalent to `C-f', `C-b', `C-n' and `C-p', just
+as they normally are in other modes.
+
+ The commands for motion by months and years work like those for
+weeks, but move a larger distance. The month commands `M-}' and `M-{'
+move forward or backward by an entire month's time. The year commands
+`C-x ]' and `C-x [' move forward or backward a whole year.
+
+ The easiest way to remember these commands is to consider months and
+years analogous to paragraphs and pages of text, respectively. But the
+commands themselves are not quite analogous. The ordinary Emacs
+paragraph commands move to the beginning or end of a paragraph, whereas
+these month and year commands move by an entire month or an entire
+year, which usually involves skipping across the end of a month or year.
+
+ All these commands accept a numeric argument as a repeat count. For
+convenience, the digit keys and the minus sign specify numeric
+arguments in Calendar mode even without the Meta modifier. For example,
+`100 C-f' moves point 100 days forward from its present location.
+
+\1f
+File: xemacs.info, Node: Move to Beginning or End, Next: Specified Dates, Prev: Calendar Unit Motion, Up: Calendar Motion
+
+Beginning or End of Week, Month or Year
+.......................................
+
+ A week (or month, or year) is not just a quantity of days; we think
+of weeks (months, years) as starting on particular dates. So Calendar
+mode provides commands to move to the beginning or end of a week, month
+or year:
+
+`C-a'
+ Move point to start of week (`calendar-beginning-of-week').
+
+`C-e'
+ Move point to end of week (`calendar-end-of-week').
+
+`M-a'
+ Move point to start of month (`calendar-beginning-of-month').
+
+`M-e'
+ Move point to end of month (`calendar-end-of-month').
+
+`M-<'
+ Move point to start of year (`calendar-beginning-of-year').
+
+`M->'
+ Move point to end of year (`calendar-end-of-year').
+
+ These commands also take numeric arguments as repeat counts, with the
+repeat count indicating how many weeks, months, or years to move
+backward or forward.
+
+ By default, weeks begin on Sunday. To make them begin on Monday
+instead, set the variable `calendar-week-start-day' to 1.
+
+\1f
+File: xemacs.info, Node: Specified Dates, Prev: Move to Beginning or End, Up: Calendar Motion
+
+Particular Dates
+................
+
+ Calendar mode provides commands for moving to a particular date
+specified in various ways.
+
+`g d'
+ Move point to specified date (`calendar-goto-date').
+
+`o'
+ Center calendar around specified month (`calendar-other-month').
+
+`.'
+ Move point to today's date (`calendar-goto-today').
+
+ `g d' (`calendar-goto-date') prompts for a year, a month, and a day
+of the month, and then moves to that date. Because the calendar
+includes all dates from the beginning of the current era, you must type
+the year in its entirety; that is, type `1990', not `90'.
+
+ `o' (`calendar-other-month') prompts for a month and year, then
+centers the three-month calendar around that month.
+
+ You can return to today's date with `.' (`calendar-goto-today').

+
+Scrolling the Calendar through Time
+-----------------------------------
+
+ The calendar display scrolls automatically through time when you
+move out of the visible portion. You can also scroll it manually.
+Imagine that the calendar window contains a long strip of paper with
+the months on it. Scrolling it means moving the strip so that new
+months become visible in the window.
+
+`C-x <'
+ Scroll calendar one month forward (`scroll-calendar-left').
+
+`C-x >'
+ Scroll calendar one month backward (`scroll-calendar-right').
+
+`C-v'
+`<NEXT>'
+ Scroll calendar three months forward
+ (`scroll-calendar-left-three-months').
+
+`M-v'
+`<PRIOR>'
+ Scroll calendar three months backward
+ (`scroll-calendar-right-three-months').
+
+ The most basic calendar scroll commands scroll by one month at a
+time. This means that there are two months of overlap between the
+display before the command and the display after. `C-x <' scrolls the
+calendar contents one month to the left; that is, it moves the display
+forward in time. `C-x >' scrolls the contents to the right, which
+moves backwards in time.
+
+ The commands `C-v' and `M-v' scroll the calendar by an entire
+"screenful"--three months--in analogy with the usual meaning of these
+commands. `C-v' makes later dates visible and `M-v' makes earlier
+dates visible. These commands take a numeric argument as a repeat
+count; in particular, since `C-u' multiplies the next command by four,
+typing `C-u C-v' scrolls the calendar forward by a year and typing `C-u
+M-v' scrolls the calendar backward by a year.
+
+ The function keys <NEXT> and <PRIOR> are equivalent to `C-v' and
+`M-v', just as they are in other modes.
+

+
+The Mark and the Region
+-----------------------
+
+ The concept of the mark applies to the calendar just as to any other
+buffer, but it marks a _date_, not a _position_ in the buffer. The
+region consists of the days between the mark and point (including the
+starting and stopping dates).
+
+`C-SPC'
+ Set the mark to today's date (`calendar-set-mark').
+
+`C-@'
+ The same.
+
+`C-x C-x'
+ Interchange mark and point (`calendar-exchange-point-and-mark').
+
+`M-='
+ Display the number of days in the current region
+ (`calendar-count-days-region').
+
+ You set the mark in the calendar, as in any other buffer, by using
+`C-@' or `C-SPC' (`calendar-set-mark'). You return to the marked date
+with the command `C-x C-x' (`calendar-exchange-point-and-mark') which
+puts the mark where point was and point where mark was. The calendar
+is scrolled as necessary, if the marked date was not visible on the
+screen. This does not change the extent of the region.
+
+ To determine the number of days in the region, type `M-='
+(`calendar-count-days-region'). The numbers of days printed is
+_inclusive_; that is, it includes the days specified by mark and point.
+
+ The main use of the mark in the calendar is to remember dates that
+you may want to go back to. To make this feature more useful, the mark
+ring (*note Mark Ring::) operates exactly as in other buffers: Emacs
+remembers 16 previous locations of the mark. To return to a marked
+date, type `C-u C-SPC' (or `C-u C-@'); this is the command
+`calendar-set-mark' given a numeric argument. It moves point to where
+the mark was, restores the mark from the ring of former marks, and
+stores the previous point at the end of the mark ring. So, repeated
+use of this command moves point through all the old marks on the ring,
+one by one.

-
-Commands to Add to the Diary
-----------------------------
-
- While in the calendar, there are several commands to create diary
-entries:
-
-`i d'
- Add a diary entry for the selected date (`insert-diary-entry').
-
-`i w'
- Add a diary entry for the selected day of the week
- (`insert-weekly-diary-entry').
-
-`i m'
- Add a diary entry for the selected day of the month
- (`insert-monthly-diary-entry').
-
-`i y'
- Add a diary entry for the selected day of the year
- (`insert-yearly-diary-entry').
-
- You can make a diary entry for a specific date by selecting that date
-in the calendar window and typing the `i d' command. This command
-displays the end of your diary file in another window and inserts the
-date; you can then type the rest of the diary entry.
-
- If you want to make a diary entry that applies to a specific day of
-the week, select that day of the week (any occurrence will do) and type
-`i w'. This inserts the day-of-week as a generic date; you can then
-type the rest of the diary entry. You can make a monthly diary entry in
-the same fashion. Select the day of the month, use the `i m' command,
-and type rest of the entry. Similarly, you can insert a yearly diary
-entry with the `i y' command.
-
- All of the above commands make marking diary entries by default. To
-make a nonmarking diary entry, give a numeric argument to the command.
-For example, `C-u i w' makes a nonmarking weekly diary entry.
-
- When you modify the diary file, be sure to save the file before
-exiting Emacs.

-Special Diary Entries
----------------------
-
- In addition to entries based on calendar dates, the diary file can
-contain "sexp entries" for regular events such as anniversaries. These
-entries are based on Lisp expressions (sexps) that Emacs evaluates as
-it scans the diary file. Instead of a date, a sexp entry contains `%%'
-followed by a Lisp expression which must begin and end with
-parentheses. The Lisp expression determines which dates the entry
-applies to.
-
- Calendar mode provides commands to insert certain commonly used sexp
-entries:
-
-`i a'
- Add an anniversary diary entry for the selected date
- (`insert-anniversary-diary-entry').
-
-`i b'
- Add a block diary entry for the current region
- (`insert-block-diary-entry').
-
-`i c'
- Add a cyclic diary entry starting at the date
- (`insert-cyclic-diary-entry').
-
- If you want to make a diary entry that applies to the anniversary of
-a specific date, move point to that date and use the `i a' command.
-This displays the end of your diary file in another window and inserts
-the anniversary description; you can then type the rest of the diary
-entry. The entry looks like this:
-
- The effect of `i a' is to add a `diary-anniversary' sexp to your
-diary file. You can also add one manually, for instance:
-
- %%(diary-anniversary 10 31 1948) Arthur's birthday
-
-This entry applies to October 31 in any year after 1948; `10 31 1948'
-specifies the date. (If you are using the European calendar style, the
-month and day are interchanged.) The reason this expression requires a
-beginning year is that advanced diary functions can use it to calculate
-the number of elapsed years.
-
- A "block" diary entry applies to a specified range of consecutive
-dates. Here is a block diary entry that applies to all dates from June
-24, 1990 through July 10, 1990:
-
- %%(diary-block 6 24 1990 7 10 1990) Vacation
-
-The `6 24 1990' indicates the starting date and the `7 10 1990'
-indicates the stopping date. (Again, if you are using the European
-calendar style, the month and day are interchanged.)
-
- To insert a block entry, place point and the mark on the two dates
-that begin and end the range, and type `i b'. This command displays
-the end of your diary file in another window and inserts the block
-description; you can then type the diary entry.
-
- "Cyclic" diary entries repeat after a fixed interval of days. To
-create one, select the starting date and use the `i c' command. The
-command prompts for the length of interval, then inserts the entry,
-which looks like this:
-
- %%(diary-cyclic 50 3 1 1990) Renew medication
-
-This entry applies to March 1, 1990 and every 50th day following; `3 1
-1990' specifies the starting date. (If you are using the European
-calendar style, the month and day are interchanged.)
-
- All three of these commands make marking diary entries. To insert a
-nonmarking entry, give a numeric argument to the command. For example,
-`C-u i a' makes a nonmarking anniversary diary entry.
-
- Marking sexp diary entries in the calendar is _extremely_
-time-consuming, since every date visible in the calendar window must be
-individually checked. So it's a good idea to make sexp diary entries
-nonmarking (with `&') when possible.
-
- Another sophisticated kind of sexp entry, a "floating" diary entry,
-specifies a regularly occurring event by offsets specified in days,
-weeks, and months. It is comparable to a crontab entry interpreted by
-the `cron' utility. Here is a nonmarking, floating diary entry that
-applies to the last Thursday in November:
-
- &%%(diary-float 11 4 -1) American Thanksgiving
-
-The 11 specifies November (the eleventh month), the 4 specifies Thursday
-(the fourth day of the week, where Sunday is numbered zero), and the -1
-specifies "last" (1 would mean "first", 2 would mean "second", -2 would
-mean "second-to-last", and so on). The month can be a single month or
-a list of months. Thus you could change the 11 above to `'(1 2 3)' and
-have the entry apply to the last Thursday of January, February, and
-March. If the month is `t', the entry applies to all months of the
-year.
-
- The sexp feature of the diary allows you to specify diary entries
-based on any Emacs Lisp expression. You can use the library of built-in
-functions or you can write your own functions. The built-in functions
-include the ones shown in this section, plus a few others (*note Sexp
-Diary Entries::).
-
- The generality of sexps lets you specify any diary entry that you can
-describe algorithmically. Suppose you get paid on the 21st of the month
-if it is a weekday, and to the Friday before if the 21st is on a
-weekend. The diary entry
-
- &%%(let ((dayname (calendar-day-of-week date))
- (day (car (cdr date))))
- (or (and (= day 21) (memq dayname '(1 2 3 4 5)))
- (and (memq day '(19 20)) (= dayname 5)))
- ) Pay check deposited
-
-to just those dates. This example illustrates how the sexp can depend
-on the variable `date'; this variable is a list (MONTH DAY YEAR) that
-gives the Gregorian date for which the diary entries are being found.
-If the value of the sexp is `t', the entry applies to that date. If
-the sexp evaluates to `nil', the entry does _not_ apply to that date.

-
- If you set the variable `view-diary-entries-initially' to `t',
-calling up the calendar automatically displays the diary entries for
-the current date as well. The diary dates appear only if the current
-date is visible. If you add both of the following lines to your
-`.emacs' file:
-
- (setq view-diary-entries-initially t)

-
-this displays both the calendar and diary windows whenever you start
-Emacs.
-
- Similarly, if you set the variable
-`view-calendar-holidays-initially' to `t', entering the calendar
-automatically displays a list of holidays for the current three-month
-period. The holiday list appears in a separate window.
-
- You can set the variable `mark-diary-entries-in-calendar' to `t' in
-order to mark any dates with diary entries. This takes effect whenever
-the calendar window contents are recomputed. There are two ways of
-marking these dates: by changing the face (*note Faces::), if the
-display supports that, or by placing a plus sign (`+') beside the date
-otherwise.
-
- Similarly, setting the variable `mark-holidays-in-calendar' to `t'
-marks holiday dates, either with a change of face or with an asterisk
-(`*').
-
- The variable `calendar-holiday-marker' specifies how to mark a date
-as being a holiday. Its value may be a character to insert next to the
-date, or a face name to use for displaying the date. Likewise, the
-variable `diary-entry-marker' specifies how to mark a date that has
-diary entries. The calendar creates faces named `holiday-face' and
-`diary-face' for these purposes; those symbols are the default values
-of these variables, when Emacs supports multiple faces on your terminal.
-
- The variable `calendar-load-hook' is a normal hook run when the
-calendar package is first loaded (before actually starting to display
-the calendar).
-
- Starting the calendar runs the normal hook
-`initial-calendar-window-hook'. Recomputation of the calendar display
-does not run this hook. But if you leave the calendar with the `q'
-command and reenter it, the hook runs again.
-
- The variable `today-visible-calendar-hook' is a normal hook run
-after the calendar buffer has been prepared with the calendar when the
-current date is visible in the window. One use of this hook is to
-replace today's date with asterisks; to do that, use the hook function
-`calendar-star-date'.
-
- (add-hook 'today-visible-calendar-hook 'calendar-star-date)
-
-Another standard hook function marks the current date, either by
-changing its face or by adding an asterisk. Here's how to use it:
-
- (add-hook 'today-visible-calendar-hook 'calendar-mark-today)
-
-The variable `calendar-today-marker' specifies how to mark today's
-date. Its value should be a character to insert next to the date or a
-face name to use for displaying the date. A face named
-`calendar-today-face' is provided for this purpose; that symbol is the
-default for this variable when Emacs supports multiple faces on your
-terminal.
-
-A similar normal hook, `today-invisible-calendar-hook' is run if the
-current date is _not_ visible in the window.
