- Diary display works by preparing the diary buffer and then running the
-hook @code{diary-display-hook}. The default value of this hook
-(@code{diary-simple-display}) hides the irrelevant diary entries and
-then displays the buffer. However, if you specify the hook as follows,
-
-@cindex diary buffer
@findex diary-fancy-display
-@example
-(add-hook 'diary-display-hook 'diary-fancy-display)
-@end example
+@cindex diary buffer
-@noindent
-this enables fancy diary display. It displays diary entries and
-holidays by copying them into a special buffer that exists only for the
-sake of display. Copying to a separate buffer provides an opportunity
-to change the displayed text to make it prettier---for example, to sort
-the entries by the dates they apply to.
-
- As with simple diary display, you can print a hard copy of the buffer
-with @code{diary-print-entries}. To print a hard copy of a day-by-day
-diary for a week, position point on Sunday of that week, type
-@kbd{7 d}, and then do @kbd{M-x diary-print-entries}. As usual, the
-inclusion of the holidays slows down the display slightly; you can speed
-things up by setting the variable @code{diary-show-holidays-flag} to
-@code{nil}.

+
+ The alternative display method @code{diary-simple-display} shows the
+actual diary buffer, and uses invisible text to hide entries that don't
+apply. Holidays are shown in the mode line. The advantage of this
+method is that you can edit the buffer and save your changes directly to
+the diary file. This method is not as flexible as the fancy method,
+however. For example, it cannot sort entries. Another disadvantage is
+that invisible text can be confusing. For example, if you copy a region
+of text in order to paste it elsewhere, invisible text may be included.
+Similarly, since the diary buffer as you see it is an illusion, simply
+printing the buffer may not print what you see on your screen.
+
+@vindex diary-print-entries-hook
+@findex diary-print-entries
+ For this reason, there is a special command to print hard copy of the
+diary buffer @emph{as it appears}; this command is @kbd{M-x
+diary-print-entries}. It works with either display method, although
+with the fancy display you can also print the buffer like any other. To
+print a hard copy of a day-by-day diary for a week, position point on
+the first day of the week, type @kbd{7 d}, and then do @kbd{M-x
+diary-print-entries}. As usual, the inclusion of the holidays slows
+down the display slightly; you can speed things up by setting the
+variable @code{diary-show-holidays-flag} to @code{nil}.
+
+ This command prepares a temporary buffer that contains only the diary
+entries currently visible in the diary buffer. Unlike with the simple
+display, the other irrelevant entries are really absent, not just
+hidden. After preparing the buffer, it runs the hook
+@code{diary-print-entries-hook}. The default value of this hook sends
+the data directly to the printer with the command @code{lpr-buffer}
+@iftex
+(@pxref{Printing,,, emacs, the Emacs Manual}).
+@end iftex
+@ifnottex
+(@pxref{Printing}).
+@end ifnottex
+If you want to use a different command to do the
+printing, just change the value of this hook. Other uses might include,
+for example, rearranging the lines into order by day and time.
+
+ You can edit the diary entries as they appear in the simple diary
+window, but it is important to remember that the buffer displayed
+contains the @emph{entire} diary file, with portions of it concealed
+from view. This means, for instance, that the @kbd{C-f}
+(@code{forward-char}) command can put point at what appears to be the
+end of the line, but what is in reality the middle of some concealed
+line.
+
+ @emph{Be careful when editing the diary entries in the simple display!}
+Inserting additional lines or adding/deleting characters in the middle
+of a visible line cannot cause problems, but editing at the end of a
+line may not do what you expect. Deleting a line may delete other
+invisible entries that follow it. Before editing the simple diary
+buffer, it is best to display the entire file with @kbd{s}
+(@code{diary-show-all-entries}).

@noindent
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.
-
- Fancy diary display also has the ability to process included diary
-files. This permits a group of people to share a diary file for events
-that apply to all of them. Lines in the diary file of this form:

+of the hook list, in case earlier members of the list change the order
+of the diary entries, or add items.
+
+@vindex diary-comment-start
+ You can write @samp{comments} in diary entries, by setting the
+variables @code{diary-comment-start} and @code{diary-comment-end} to
+strings that delimit comments. The fancy display does not print
+comments. You might want to put meta-data for the use of other packages

@subsection Sexp Entries and the Fancy Diary Display
@cindex sexp diary entries
+@vindex diary-sexp-entry-symbol
Sexp diary entries allow you to do more than just have complicated
-conditions under which a diary entry applies. If you use the fancy
-diary display, sexp entries can generate the text of the entry depending
-on the date itself. For example, an anniversary diary entry can insert
+conditions under which a diary entry applies. Sexp entries should be
+preceded by @code{diary-sexp-entry-symbol} (default @samp{%%}) in the
+diary file. With the fancy diary display, sexp entries can generate the
+text of the entry depending on the date itself.
+
+For example, an anniversary diary entry can insert
the number of years since the anniversary date into the text of the
diary entry. Thus the @samp{%d} in this diary entry:
