 The day and week commands are natural analogues of the usual Emacs

 moves to the same day in the previous week.

 The commands for motion by months and years work like those for
 weeks, but move a larger distance.  The month commands @kbd{M-@}} and
 @kbd{M-@{} move forward or backward by an entire month's time.  The
-year commands @kbd{C-x ]} and @kbd{C-x [} move forward or backward a
+year commands @kbd{C-x ]} and @w{@kbd{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.

 @subsection Scrolling the Calendar through Time
+@cindex scrolling in the calendar
 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.

 @findex scroll-calendar-right
 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.  @kbd{C-x <} scrolls
 the calendar contents one month to the left; that is, it moves the
 display forward in time.  @kbd{C-x >} scrolls the contents to the
 right, which moves backwards in time.

 with the command @kbd{C-x C-x} (@code{calendar-exchange-point-and-mark})

 is scrolled as necessary, if the marked date was not visible on the

 @cindex mark ring
 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
 (@pxref{Mark Ring}) operates exactly as in other buffers:  Emacs remembers
 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.

-You can also use just numbers to express a date, as in
-@samp{@var{month}/@var{day}} or
-@samp{@var{month}/@var{day}/@var{year}}.  This must be followed by a
-nondigit.  In the date itself, @var{month} and @var{day} are numbers of

 You can inhibit the marking of certain diary entries in the calendar
 window; to do this, insert an ampersand (@samp{&}) at the beginning of
 the entry, before the date.  This has no effect on display of the entry

 that would otherwise mark many different dates.

 name with no following blanks or punctuation, then the diary window
 display doesn't include that line; only the continuation lines appear.

 As with simple diary display, you can print a hard copy of the buffer
 with @code{print-diary-entries}.  To print a hard copy of a day-by-day
 diary for a week by positioning point on Sunday of that week, type
 @kbd{7 d} and then do @kbd{M-x print-diary-entries}.  As usual, the
 @code{list-diary-entries-hook} to sort each day's diary entries by their
 time of day.  Add this line to your @file{.emacs} file:
 @findex sort-diary-entries
 @example
-(add-hook 'list-diary-entries-hook 'sort-diary-entries)
+(add-hook 'list-diary-entries-hook 'sort-diary-entries t)
 @end example

 For each day, this sorts diary entries that begin with a recognizable
 time of day according to their times.  Diary entries without times come
 first within each day.

+Suppose you get paid on the 21st of the month if it is a weekday, and
+on the Friday before if the 21st is on a weekend.  Here is how to write
+a sexp diary entry that matches those dates:
 @smallexample
 &%%(let ((dayname (calendar-day-of-week date))
 (day (car (cdr date))))
 (or (and (= day 21) (memq dayname '(1 2 3 4 5)))
 entries are being found.  If the value of the expression is @code{t},
 the entry applies to that date.  If the expression evaluates to
 @code{nil}, the entry does @emph{not} apply to that date.
 The following sexp diary entries take advantage of the ability (in the fancy
