+Deletion and Killing
+====================
+
+ Most commands that erase text from the buffer save it. You can get
+the text back if you change your mind, or you can move or copy it to
+other parts of the buffer. Commands which erase text and save it in the
+kill ring are known as "kill" commands. Some other commands erase text
+but do not save it; they are known as "delete" commands. (This
+distinction is made only for erasing text in the buffer.)
+
+ The commands' names and individual descriptions use the words `kill'
+and `delete' to indicate what they do. If you perform a kill or delete
+command by mistake, use the `C-x u' (`undo') command to undo it (*note
+Undo::). The delete commands include `C-d' (`delete-char') and <DEL>
+(`delete-backward-char'), which delete only one character at a time,
+and those commands that delete only spaces or newlines. Commands that
+can destroy significant amounts of nontrivial data usually kill.
+
+Deletion
+--------
+
+`C-d'
+ Delete next character (`delete-char').
+
+`<DEL>'
+ Delete previous character (`delete-backward-char').
+
+`M-\'
+ Delete spaces and tabs around point (`delete-horizontal-space').
+
+`M-<SPC>'
+ Delete spaces and tabs around point, leaving one space
+ (`just-one-space').
+
+`C-x C-o'
+ Delete blank lines around the current line (`delete-blank-lines').
+
+`M-^'
+ Join two lines by deleting the intervening newline, and any
+ indentation following it (`delete-indentation').
+
+ The most basic delete commands are `C-d' (`delete-char') and <DEL>
+(`delete-backward-char'). `C-d' deletes the character after point, the
+one the cursor is "on top of". Point doesn't move. <DEL> deletes the
+character before the cursor, and moves point back. You can delete
+newlines like any other characters in the buffer; deleting a newline
+joins two lines. Actually, `C-d' and <DEL> aren't always delete
+commands; if you give them an argument, they kill instead, since they
+can erase more than one character this way.
+
+ The other delete commands delete only formatting characters: spaces,
+tabs and newlines. `M-\' (`delete-horizontal-space') deletes all
+spaces and tab characters before and after point. `M-<SPC>'
+(`just-one-space') does the same but leaves a single space after point,
+regardless of the number of spaces that existed previously (even zero).
+
+ `C-x C-o' (`delete-blank-lines') deletes all blank lines after the
+current line. If the current line is blank, it deletes all blank lines
+preceding the current line as well as leaving one blank line, the
+current line. `M-^' (`delete-indentation') joins the current line and
+the previous line, or, if given an argument, joins the current line and
+the next line by deleting a newline and all surrounding spaces, possibly
+leaving a single space. *Note M-^: Indentation.
+
+Killing by Lines
+----------------
+
+`C-k'
+ Kill rest of line or one or more lines (`kill-line').
+
+ The simplest kill command is `C-k'. If given at the beginning of a
+line, it kills all the text on the line, leaving the line blank. If
+given on a blank line, the blank line disappears. As a consequence, a
+line disappears completely if you go to the front of a non-blank line
+and type `C-k' twice.
+
+ More generally, `C-k' kills from point up to the end of the line,
+unless it is at the end of a line. In that case, it kills the newline
+following the line, thus merging the next line into the current one.
+Emacs ignores invisible spaces and tabs at the end of the line when
+deciding which case applies: if point appears to be at the end of the
+line, you can be sure the newline will be killed.
+
+ If you give `C-k' a positive argument, it kills that many lines and
+the newlines that follow them (however, text on the current line before
+point is not killed). With a negative argument, `C-k' kills back to a
+number of line beginnings. An argument of -2 means kill back to the
+second line beginning. If point is at the beginning of a line, that
+line beginning doesn't count, so `C-u - 2 C-k' with point at the front
+of a line kills the two previous lines.
+
+ `C-k' with an argument of zero kills all the text before point on the
+current line.
+
+Other Kill Commands
+-------------------
+
+`C-w'
+ Kill region (from point to the mark) (`kill-region'). *Note
+ Words::.
+
+`M-d'
+ Kill word (`kill-word').
+
+`M-<DEL>'
+ Kill word backwards (`backward-kill-word').
+
+`C-x <DEL>'
+ Kill back to beginning of sentence (`backward-kill-sentence').
+ *Note Sentences::.
+
+`M-k'
+ Kill to end of sentence (`kill-sentence').
+
+`C-M-k'
+ Kill sexp (`kill-sexp'). *Note Lists::.
+
+`M-z CHAR'
+ Kill up to next occurrence of CHAR (`zap-to-char').
+
+ `C-w' (`kill-region') is a very general kill command; it kills
+everything between point and the mark. You can use this command to kill
+any contiguous sequence of characters by first setting the mark at one
+end of a sequence of characters, then going to the other end and typing
+`C-w'.
+
+ A convenient way of killing is combined with searching: `M-z'
+(`zap-to-char') reads a character and kills from point up to (but not
+including) the next occurrence of that character in the buffer. If
+there is no next occurrence, killing goes to the end of the buffer. A
+numeric argument acts as a repeat count. A negative argument means to
+search backward and kill text before point.
+
+ Other syntactic units can be killed: words, with `M-<DEL>' and `M-d'
+(*note Words::); sexps, with `C-M-k' (*note Lists::); and sentences,
+with `C-x <DEL>' and `M-k' (*note Sentences::).

+Yanking
+=======
+
+ "Yanking" means getting back text which was killed. Some systems
+call this "pasting". The usual way to move or copy text is to kill it
+and then yank it one or more times.
+
+`C-y'
+ Yank last killed text (`yank').
+
+`M-y'
+ Replace re-inserted killed text with the previously killed text
+ (`yank-pop').
+
+`M-w'
+ Save region as last killed text without actually killing it
+ (`copy-region-as-kill').
+
+`C-M-w'
+ Append next kill to last batch of killed text (`append-next-kill').

+
+The Kill Ring
+-------------
+
+ All killed text is recorded in the "kill ring", a list of blocks of
+text that have been killed. There is only one kill ring, used in all
+buffers, so you can kill text in one buffer and yank it in another
+buffer. This is the usual way to move text from one file to another.
+(*Note Accumulating Text::, for some other ways.)
+
+ If you have two separate Emacs processes, you cannot use the kill
+ring to move text. If you are using XEmacs under X, however, you can
+use the X selection mechanism to move text from one to another.
+
+ If you are using XEmacs under X and have one Emacs process with
+multiple frames, they do share the same kill ring. You can kill or
+copy text in one Emacs frame, then yank it in the other frame belonging
+to the same process.
+
+ The command `C-y' (`yank') reinserts the text of the most recent
+kill. It leaves the cursor at the end of the text and sets the mark at
+the beginning of the text. *Note Mark::.
+
+ `C-u C-y' yanks the text, leaves the cursor in front of the text,
+and sets the mark after it, if the argument is with just a `C-u'. Any
+other argument, including `C-u' and digits, has different results,
+described below, under "Yanking Earlier Kills".
+
+ To copy a block of text, you can also use `M-w'
+(`copy-region-as-kill'), which copies the region into the kill ring
+without removing it from the buffer. `M-w' is similar to `C-w' followed
+by `C-y' but does not mark the buffer as "modified" and does not
+actually cut anything.

- Emacs "registers" are places in which you can save text or positions

+
+ (set-register ?z '(file . "/usr/src/xemacs/src/ChangeLog"))

+
+Bookmarks
+=========
+
+ "Bookmarks" are somewhat like registers in that they record
+positions you can jump to. Unlike registers, they have long names, and
+they persist automatically from one Emacs session to the next. The
+prototypical use of bookmarks is to record "where you were reading" in
+various files.
+
+ Note: bookmark.el is distributed in edit-utils package. You need to
+install that to use bookmark facility (*note Packages::).
+
+`C-x r m <RET>'
+ Set the bookmark for the visited file, at point.
+
+`C-x r m BOOKMARK <RET>'
+ Set the bookmark named BOOKMARK at point (`bookmark-set').
+
+`C-x r b BOOKMARK <RET>'
+ Jump to the bookmark named BOOKMARK (`bookmark-jump').
+
+`C-x r l'
+ List all bookmarks (`list-bookmarks').
+
+`M-x bookmark-save'
+ Save all the current bookmark values in the default bookmark file.
+
+ The prototypical use for bookmarks is to record one current position
+in each of several files. So the command `C-x r m', which sets a
+bookmark, uses the visited file name as the default for the bookmark
+name. If you name each bookmark after the file it points to, then you
+can conveniently revisit any of those files with `C-x r b', and move to
+the position of the bookmark at the same time.
+
+ To display a list of all your bookmarks in a separate buffer, type
+`C-x r l' (`list-bookmarks'). If you switch to that buffer, you can
+use it to edit your bookmark definitions or annotate the bookmarks.
+Type `C-h m' in that buffer for more information about its special
+editing commands.
+
+ When you kill XEmacs, XEmacs offers to save your bookmark values in
+your default bookmark file, `~/.emacs.bmk', if you have changed any
+bookmark values. You can also save the bookmarks at any time with the
+`M-x bookmark-save' command. The bookmark commands load your default
+bookmark file automatically. This saving and loading is how bookmarks
+persist from one XEmacs session to the next.
+
+ If you set the variable `bookmark-save-flag' to 1, then each command
+that sets a bookmark will also save your bookmarks; this way, you don't
+lose any bookmark values even if XEmacs crashes. (The value, if a
+number, says how many bookmark modifications should go by between
+saving.)
+
+ Bookmark position values are saved with surrounding context, so that
+`bookmark-jump' can find the proper position even if the file is
+modified slightly. The variable `bookmark-search-size' says how many
+characters of context to record, on each side of the bookmark's
+position.
+
+ Here are some additional commands for working with bookmarks:
+
+`M-x bookmark-load <RET> FILENAME <RET>'
+ Load a file named FILENAME that contains a list of bookmark
+ values. You can use this command, as well as `bookmark-write', to
+ work with other files of bookmark values in addition to your
+ default bookmark file.
+
+`M-x bookmark-write <RET> FILENAME <RET>'
+ Save all the current bookmark values in the file FILENAME.
+
+`M-x bookmark-delete <RET> BOOKMARK <RET>'
+ Delete the bookmark named BOOKMARK.
+
+`M-x bookmark-insert-location <RET> BOOKMARK <RET>'
+ Insert in the buffer the name of the file that bookmark BOOKMARK
+ points to.
+
+`M-x bookmark-insert <RET> BOOKMARK <RET>'
+ Insert in the buffer the _contents_ of the file that bookmark
+ BOOKMARK points to.

-Variables Controlling Display
-=============================
-
- This section contains information for customization only. Beginning
-users should skip it.
-
- When you reenter XEmacs after suspending, XEmacs normally clears the
-screen and redraws the entire display. On some terminals with more than
-one page of memory, it is possible to arrange the termcap entry so that
-the `ti' and `te' strings (output to the terminal when XEmacs is
-entered and exited, respectively) switch between pages of memory so as
-to use one page for XEmacs and another page for other output. In that
-case, you might want to set the variable `no-redraw-on-reenter' to
-non-`nil' so that XEmacs will assume, when resumed, that the screen
-page it is using still contains what XEmacs last wrote there.
-
- The variable `echo-keystrokes' controls the echoing of
-multi-character keys; its value is the number of seconds of pause
-required to cause echoing to start, or zero, meaning don't echo at all.
-*Note Echo Area::.
-
- If the variable `ctl-arrow' is `nil', control characters in the
-buffer are displayed with octal escape sequences, all except newline and
-tab. If its value is `t', then control characters will be printed with
-an up-arrow, for example `^A'.
-
- If its value is not `t' and not `nil', then characters whose code is
-greater than 160 (that is, the space character (32) with its high bit
-set) will be assumed to be printable, and will be displayed without
-alteration. This is the default when running under X Windows, since
-XEmacs assumes an ISO/8859-1 character set (also known as "Latin1").
-The `ctl-arrow' variable may also be set to an integer, in which case
-all characters whose codes are greater than or equal to that value will
-be assumed to be printable.
-
- Altering the value of `ctl-arrow' makes it local to the current
-buffer; until that time, the default value is in effect. *Note
-Locals::.
-
- Normally, a tab character in the buffer is displayed as whitespace
-which extends to the next display tab stop position, and display tab
-stops come at intervals equal to eight spaces. The number of spaces
-per tab is controlled by the variable `tab-width', which is made local
-by changing it, just like `ctl-arrow'. Note that how the tab character
-in the buffer is displayed has nothing to do with the definition of
-<TAB> as a command.
-
- If you set the variable `selective-display-ellipses' to `nil', the
-three dots at the end of a line that precedes invisible lines do not
-appear. There is no visible indication of the invisible lines. This
-variable becomes local automatically when set.

-Searching and Replacement
-*************************
-
- Like other editors, Emacs has commands for searching for occurrences
-of a string. The principal search command is unusual in that it is
-"incremental": it begins to search before you have finished typing the
-search string. There are also non-incremental search commands more like
-those of other editors.
-
- Besides the usual `replace-string' command that finds all
-occurrences of one string and replaces them with another, Emacs has a
-fancy replacement command called `query-replace' which asks
-interactively which occurrences to replace.
-
-* Menu:
-
-* Incremental Search:: Search happens as you type the string.
-* Non-Incremental Search:: Specify entire string and then search.
-* Word Search:: Search for sequence of words.
-* Regexp Search:: Search for match for a regexp.
-* Regexps:: Syntax of regular expressions.
-* Search Case:: To ignore case while searching, or not.
-* Replace:: Search, and replace some or all matches.
-* Other Repeating Search:: Operating on all matches for some regexp.

-Incremental Search
-==================
-
- An incremental search begins searching as soon as you type the first
-character of the search string. As you type in the search string, Emacs
-shows you where the string (as you have typed it so far) is found.
-When you have typed enough characters to identify the place you want,
-you can stop. Depending on what you do next, you may or may not need to
-terminate the search explicitly with a <RET>.
-
-`C-s'
- Incremental search forward (`isearch-forward').
-
-`C-r'
- Incremental search backward (`isearch-backward').
-
- `C-s' starts an incremental search. `C-s' reads characters from the
-keyboard and positions the cursor at the first occurrence of the
-characters that you have typed. If you type `C-s' and then `F', the
-cursor moves right after the first `F'. Type an `O', and see the
-cursor move to after the first `FO'. After another `O', the cursor is
-after the first `FOO' after the place where you started the search.
-Meanwhile, the search string `FOO' has been echoed in the echo area.
-
- The echo area display ends with three dots when actual searching is
-going on. When search is waiting for more input, the three dots are
-removed. (On slow terminals, the three dots are not displayed.)
-
- If you make a mistake in typing the search string, you can erase
-characters with <DEL>. Each <DEL> cancels the last character of the
-search string. This does not happen until Emacs is ready to read
-another input character; first it must either find, or fail to find,
-the character you want to erase. If you do not want to wait for this
-to happen, use `C-g' as described below.
-
- When you are satisfied with the place you have reached, you can type
-<RET> (or <C-m>), which stops searching, leaving the cursor where the
-search brought it. Any command not specially meaningful in searches
-also stops the search and is then executed. Thus, typing `C-a' exits
-the search and then moves to the beginning of the line. <RET> is
-necessary only if the next command you want to type is a printing
-character, <DEL>, <ESC>, or another control character that is special
-within searches (`C-q', `C-w', `C-r', `C-s', or `C-y').
-
- Sometimes you search for `FOO' and find it, but were actually
-looking for a different occurance of it. To move to the next occurrence
-of the search string, type another `C-s'. Do this as often as
-necessary. If you overshoot, you can cancel some `C-s' characters with
-<DEL>.
-
- After you exit a search, you can search for the same string again by
-typing just `C-s C-s': the first `C-s' is the key that invokes
-incremental search, and the second `C-s' means "search again".
-
- If the specified string is not found at all, the echo area displays
-the text `Failing I-Search'. The cursor is after the place where Emacs
-found as much of your string as it could. Thus, if you search for
-`FOOT', and there is no `FOOT', the cursor may be after the `FOO' in
-`FOOL'. At this point there are several things you can do. If you
-mistyped the search string, correct it. If you like the place you have
-found, you can type <RET> or some other Emacs command to "accept what
-the search offered". Or you can type `C-g', which removes from the
-search string the characters that could not be found (the `T' in
-`FOOT'), leaving those that were found (the `FOO' in `FOOT'). A second
-`C-g' at that point cancels the search entirely, returning point to
-where it was when the search started.
-
- If a search is failing and you ask to repeat it by typing another
-`C-s', it starts again from the beginning of the buffer. Repeating a
-failing backward search with `C-r' starts again from the end. This is
-called "wrapping around". `Wrapped' appears in the search prompt once
-this has happened.
-
- The `C-g' "quit" character does special things during searches; just
-what it does depends on the status of the search. If the search has
-found what you specified and is waiting for input, `C-g' cancels the
-entire search. The cursor moves back to where you started the search.
-If `C-g' is typed when there are characters in the search string that
-have not been found--because Emacs is still searching for them, or
-because it has failed to find them--then the search string characters
-which have not been found are discarded from the search string. The
-search is now successful and waiting for more input, so a second `C-g'
-cancels the entire search.
-
- To search for a control character such as `C-s' or <DEL> or <ESC>,
-you must quote it by typing `C-q' first. This function of `C-q' is
-analogous to its meaning as an Emacs command: it causes the following
-character to be treated the way a graphic character would normally be
-treated in the same context.
-
- To search backwards, you can use `C-r' instead of `C-s' to start the
-search; `C-r' is the key that runs the command (`isearch-backward') to
-search backward. You can also use `C-r' to change from searching
-forward to searching backwards. Do this if a search fails because the
-place you started was too far down in the file. Repeated `C-r' keeps
-looking for more occurrences backwards. `C-s' starts going forward
-again. You can cancel `C-r' in a search with <DEL>.
-
- The characters `C-y' and `C-w' can be used in incremental search to
-grab text from the buffer into the search string. This makes it
-convenient to search for another occurrence of text at point. `C-w'
-copies the word after point as part of the search string, advancing
-point over that word. Another `C-s' to repeat the search will then
-search for a string including that word. `C-y' is similar to `C-w' but
-copies the rest of the current line into the search string.
-
- The characters `M-p' and `M-n' can be used in an incremental search
-to recall things which you have searched for in the past. A list of
-the last 16 things you have searched for is retained, and `M-p' and
-`M-n' let you cycle through that ring.
-
- The character `M-<TAB>' does completion on the elements in the
-search history ring. For example, if you know that you have recently
-searched for the string `POTATOE', you could type `C-s P O M-<TAB>'.
-If you had searched for other strings beginning with `PO' then you
-would be shown a list of them, and would need to type more to select
-one.
-
- You can change any of the special characters in incremental search
-via the normal keybinding mechanism: simply add a binding to the
-`isearch-mode-map'. For example, to make the character `C-b' mean
-"search backwards" while in isearch-mode, do this:
-
- (define-key isearch-mode-map "\C-b" 'isearch-repeat-backward)
-
- These are the default bindings of isearch-mode:
-
-`DEL'
- Delete a character from the incremental search string
- (`isearch-delete-char').
-
-`RET'
- Exit incremental search (`isearch-exit').
-
-`C-q'
- Quote special characters for incremental search
- (`isearch-quote-char').
-
-`C-s'
- Repeat incremental search forward (`isearch-repeat-forward').
-
-`C-r'
- Repeat incremental search backward (`isearch-repeat-backward').
-
-`C-y'
- Pull rest of line from buffer into search string
- (`isearch-yank-line').
-
-`C-w'
- Pull next word from buffer into search string
- (`isearch-yank-word').
-
-`C-g'
- Cancels input back to what has been found successfully, or aborts
- the isearch (`isearch-abort').
-
-`M-p'
- Recall the previous element in the isearch history ring
- (`isearch-ring-retreat').
-
-`M-n'
- Recall the next element in the isearch history ring
- (`isearch-ring-advance').
-
-`M-<TAB>'
- Do completion on the elements in the isearch history ring
- (`isearch-complete').
-
- Any other character which is normally inserted into a buffer when
-typed is automatically added to the search string in isearch-mode.
-
-Slow Terminal Incremental Search
---------------------------------
-
- Incremental search on a slow terminal uses a modified style of
-display that is designed to take less time. Instead of redisplaying
-the buffer at each place the search gets to, it creates a new
-single-line window and uses that to display the line the search has
-found. The single-line window appears as soon as point gets outside of
-the text that is already on the screen.
-
- When the search is terminated, the single-line window is removed.
-Only at this time the window in which the search was done is
-redisplayed to show its new value of point.
-
- The three dots at the end of the search string, normally used to
-indicate that searching is going on, are not displayed in slow style
-display.
-
- The slow terminal style of display is used when the terminal baud
-rate is less than or equal to the value of the variable
-`search-slow-speed', initially 1200.
-
- The number of lines to use in slow terminal search display is
-controlled by the variable `search-slow-window-lines'. Its normal
-value is 1.

-Non-Incremental Search
-======================
-
- Emacs also has conventional non-incremental search commands, which
-require you type the entire search string before searching begins.
-
-`C-s <RET> STRING <RET>'
- Search for STRING.
-
-`C-r <RET> STRING <RET>'
- Search backward for STRING.
-
- To do a non-incremental search, first type `C-s <RET>' (or `C-s
-C-m'). This enters the minibuffer to read the search string.
-Terminate the string with <RET> to start the search. If the string is
-not found, the search command gets an error.
-
- By default, `C-s' invokes incremental search, but if you give it an
-empty argument, which would otherwise be useless, it invokes
-non-incremental search. Therefore, `C-s <RET>' invokes non-incremental
-search. `C-r <RET>' also works this way.
-
- Forward and backward non-incremental searches are implemented by the
-commands `search-forward' and `search-backward'. You can bind these
-commands to keys. The reason that incremental search is programmed to
-invoke them as well is that `C-s <RET>' is the traditional sequence of
-characters used in Emacs to invoke non-incremental search.
-
- Non-incremental searches performed using `C-s <RET>' do not call
-`search-forward' right away. They first check if the next character is
-`C-w', which requests a word search. *Note Word Search::.

-Word Search
-===========
-
- Word search looks for a sequence of words without regard to how the
-words are separated. More precisely, you type a string of many words,
-using single spaces to separate them, and the string is found even if
-there are multiple spaces, newlines or other punctuation between the
-words.
-
- Word search is useful in editing documents formatted by text
-formatters. If you edit while looking at the printed, formatted
-version, you can't tell where the line breaks are in the source file.
-Word search, allows you to search without having to know the line
-breaks.
-
-`C-s <RET> C-w WORDS <RET>'
- Search for WORDS, ignoring differences in punctuation.
-
-`C-r <RET> C-w WORDS <RET>'
- Search backward for WORDS, ignoring differences in punctuation.
-
- Word search is a special case of non-incremental search. It is
-invoked with `C-s <RET> C-w' followed by the search string, which must
-always be terminated with another <RET>. Being non-incremental, this
-search does not start until the argument is terminated. It works by
-constructing a regular expression and searching for that. *Note Regexp
-Search::.
-
- You can do a backward word search with `C-r <RET> C-w'.
-
- Forward and backward word searches are implemented by the commands
-`word-search-forward' and `word-search-backward'. You can bind these
-commands to keys. The reason that incremental search is programmed to
-invoke them as well is that `C-s <RET> C-w' is the traditional Emacs
-sequence of keys for word search.
