-Rectangles
-==========
-
- The rectangle commands affect rectangular areas of text: all
-characters between a certain pair of columns, in a certain range of
-lines. Commands are provided to kill rectangles, yank killed
-rectangles, clear them out, or delete them. Rectangle commands are
-useful with text in multicolumnar formats, like code with comments at
-the right, or for changing text into or out of such formats.
-
- To specify the rectangle a command should work on, put the mark at
-one corner and point at the opposite corner. The specified rectangle is
-called the "region-rectangle" because it is controlled about the same
-way the region is controlled. Remember that a given combination of
-point and mark values can be interpreted either as specifying a region
-or as specifying a rectangle; it is up to the command that uses them to
-choose the interpretation.
-
-`M-x delete-rectangle'
- Delete the text of the region-rectangle, moving any following text
- on each line leftward to the left edge of the region-rectangle.
-
-`M-x kill-rectangle'
- Similar, but also save the contents of the region-rectangle as the
- "last killed rectangle".
-
-`M-x yank-rectangle'
- Yank the last killed rectangle with its upper left corner at point.
-
-`M-x open-rectangle'
- Insert blank space to fill the space of the region-rectangle. The
- previous contents of the region-rectangle are pushed rightward.
-
-`M-x clear-rectangle'
- Clear the region-rectangle by replacing its contents with spaces.
-
- The rectangle operations fall into two classes: commands deleting and
-moving rectangles, and commands for blank rectangles.
-
- There are two ways to get rid of the text in a rectangle: you can
-discard the text (delete it) or save it as the "last killed" rectangle.
-The commands for these two ways are `M-x delete-rectangle' and `M-x
-kill-rectangle'. In either case, the portion of each line that falls
-inside the rectangle's boundaries is deleted, causing following text
-(if any) on the line to move left.
-
- Note that "killing" a rectangle is not killing in the usual sense;
-the rectangle is not stored in the kill ring, but in a special place
-that only records the most recently killed rectangle (that is, does not
-append to a killed rectangle). Different yank commands have to be used
-and only one rectangle is stored, because yanking a rectangle is quite
-different from yanking linear text and yank-popping commands are
-difficult to make sense of.
-
- Inserting a rectangle is the opposite of deleting one. You specify
-where to put the upper left corner by putting point there. The
-rectangle's first line is inserted at point, the rectangle's second line
-is inserted at a point one line vertically down, and so on. The number
-of lines affected is determined by the height of the saved rectangle.
-
- To insert the last killed rectangle, type `M-x yank-rectangle'.
-This can be used to convert single-column lists into double-column
-lists; kill the second half of the list as a rectangle and then yank it
-beside the first line of the list.
-
- There are two commands for working with blank rectangles: `M-x
-clear-rectangle' erases existing text, and `M-x open-rectangle' inserts
-a blank rectangle. Clearing a rectangle is equivalent to deleting it
-and then inserting a blank rectangle of the same size.
-
- Rectangles can also be copied into and out of registers. *Note
-Rectangle Registers: RegRect.

-Registers
-*********
-
- Emacs "registers" are places in which you can save text or positions
-for later use. Text saved in a register can be copied into the buffer
-once or many times; a position saved in a register is used by moving
-point to that position. Rectangles can also be copied into and out of
-registers (*note Rectangles::).
-
- Each register has a name, which is a single character. A register
-can store either a piece of text, a position, or a rectangle, but only
-one thing at any given time. Whatever you store in a register remains
-there until you store something else in that register.
-
-* Menu:
-
-* RegPos:: Saving positions in registers.
-* RegText:: Saving text in registers.
-* RegRect:: Saving rectangles in registers.
-
-`M-x view-register <RET> R'
- Display a description of what register R contains.
-
- `M-x view-register' reads a register name as an argument and then
-displays the contents of the specified register.

-
-Saving Positions in Registers
-=============================
-
- Saving a position records a spot in a buffer so you can move back
-there later. Moving to a saved position re-selects the buffer and
-moves point to the spot.
-
-`C-x r SPC R'
- Save the location of point in register R (`point-to-register').
-
-`C-x r j R'
- Jump to the location saved in register R (`register-to-point').
-
- To save the current location of point in a register, choose a name R
-and type `C-x r SPC R'. The register R retains the location thus saved
-until you store something else in that register.
-
- The command `C-x r j R' moves point to the location recorded in
-register R. The register is not affected; it continues to record the
-same location. You can jump to the same position using the same
-register as often as you want.

-
-Saving Text in Registers
-========================
-
- When you want to insert a copy of the same piece of text many times,
-it can be impractical to use the kill ring, since each subsequent kill
-moves the piece of text further down on the ring. It becomes hard to
-keep track of the argument needed to retrieve the same text with `C-y'.
-An alternative is to store the text in a register with `C-x r s'
-(`copy-to-register') and then retrieve it with `C-x r g'
-(`insert-register').
-
-`C-x r s R'
- Copy region into register R (`copy-to-register').
-
-`C-x r g R'
- Insert text contents of register R (`insert-register').
-
- `C-x r s R' stores a copy of the text of the region into the
-register named R. Given a numeric argument, `C-x r s' deletes the text
-from the buffer as well.
-
- `C-x r g R' inserts the text from register R in the buffer. By
-default it leaves point before the text and places the mark after it.
-With a numeric argument, it puts point after the text and the mark
-before it.

-Saving Rectangles in Registers
-==============================
-
- A register can contain a rectangle instead of lines of text. The
-rectangle is represented as a list of strings. *Note Rectangles::, for
-basic information on rectangles and how to specify rectangles in a
-buffer.
-
-`C-x r r R'
- Copy the region-rectangle into register
- R(`copy-rectangle-to-register'). With a numeric argument, delete
- it as well.
-
-`C-x r g R'
- Insert the rectangle stored in register R (if it contains a
- rectangle) (`insert-register').
-
- The `C-x r g' command inserts linear text if the register contains
-that, or inserts a rectangle if the register contains one.

-Controlling the Display
-***********************
-
- Since only part of a large buffer fits in the window, XEmacs tries

- Clear frame and redisplay, scrolling the selected window to center
- point vertically within it (`recenter').
-
-`C-v'
-`pgdn'
-`next'
- Scroll forward (a windowful or a specified number of lines)
- (`scroll-up'). On most X keyboards, you can get this
- functionality using the key labelled `Page Down', which generates
- either `next' or `pgdn'.
-
-`M-v'
-`pgup'
-`prior'
- Scroll backward (`scroll-down'). On most X keyboards, you can get

-Scrolling
-=========
-
- If a buffer contains text that is too large to fit entirely within
-the window that is displaying the buffer, XEmacs shows a contiguous
-section of the text. The section shown always contains point.
-
- "Scrolling" means moving text up or down in the window so that
-different parts of the text are visible. Scrolling forward means that
-text moves up, and new text appears at the bottom. Scrolling backward
-moves text down and new text appears at the top.
-
- Scrolling happens automatically if you move point past the bottom or
-top of the window. You can also explicitly request scrolling with the
-commands in this section.
-
-`C-l'
- Clear frame and redisplay, scrolling the selected window to center
- point vertically within it (`recenter').
-
-`C-v'
-`pgdn'
-`next'
- Scroll forward (a windowful or a specified number of lines)
- (`scroll-up').
-
-`M-v'
-`pgup'
-`prior'
- Scroll backward (`scroll-down').
-
-`ARG C-l'
- Scroll so point is on line ARG (`recenter').
-
- The most basic scrolling command is `C-l' (`recenter') with no
-argument. It clears the entire frame and redisplays all windows. In
-addition, it scrolls the selected window so that point is halfway down
-from the top of the window.
-
- The scrolling commands `C-v' and `M-v' let you move all the text in
-the window up or down a few lines. `C-v' (`scroll-up') with an
-argument shows you that many more lines at the bottom of the window,
-moving the text and point up together as `C-l' might. `C-v' with a
-negative argument shows you more lines at the top of the window.
-`Meta-v' (`scroll-down') is like `C-v', but moves in the opposite
-direction.
-
- To read the buffer a windowful at a time, use `C-v' with no
-argument. `C-v' takes the last two lines at the bottom of the window
-and puts them at the top, followed by nearly a whole windowful of lines
-not previously visible. Point moves to the new top of the window if it
-was in the text scrolled off the top. `M-v' with no argument moves
-backward with similar overlap. The number of lines of overlap across a
-`C-v' or `M-v' is controlled by the variable
-`next-screen-context-lines'; by default, it is two.
-
- Another way to scroll is using `C-l' with a numeric argument. `C-l'
-does not clear the frame when given an argument; it only scrolls the
-selected window. With a positive argument N, `C-l' repositions text to
-put point N lines down from the top. An argument of zero puts point on
-the very top line. Point does not move with respect to the text;
-rather, the text and point move rigidly on the frame. `C-l' with a
-negative argument puts point that many lines from the bottom of the
-window. For example, `C-u - 1 C-l' puts point on the bottom line, and
-`C-u - 5 C-l' puts it five lines from the bottom. Just `C-u' as
-argument, as in `C-u C-l', scrolls point to the center of the frame.
-
- Scrolling happens automatically if point has moved out of the visible
-portion of the text when it is time to display. Usually scrolling is
-done to put point vertically centered within the window. However, if
-the variable `scroll-step' has a non-zero value, an attempt is made to
-scroll the buffer by that many lines; if that is enough to bring point
-back into visibility, that is what happens.

-scroll the buffer by that many lines; if that is enough to bring point
-back into visibility, that is what happens.
-
- If you set `scroll-step' to a small value because you want to use
-arrow keys to scroll the screen without recentering, the redisplay
-preemption will likely make XEmacs keep recentering the screen when
-scrolling fast, regardless of `scroll-step'. To prevent this, set
-`scroll-conservatively' to a small value, which will have the result of
-overriding the redisplay preemption.

-
-Horizontal Scrolling
-====================
-
-`C-x <'
- Scroll text in current window to the left (`scroll-left').
-
-`C-x >'
- Scroll to the right (`scroll-right').
-
- The text in a window can also be scrolled horizontally. This means
-that each line of text is shifted sideways in the window, and one or
-more characters at the beginning of each line are not displayed at all.
-When a window has been scrolled horizontally in this way, text lines
-are truncated rather than continued (*note Continuation Lines::), with
-a `$' appearing in the first column when there is text truncated to the
-left, and in the last column when there is text truncated to the right.
-
- The command `C-x <' (`scroll-left') scrolls the selected window to
-the left by N columns with argument N. With no argument, it scrolls by
-almost the full width of the window (two columns less, to be precise).
-`C-x >' (`scroll-right') scrolls similarly to the right. The window
-cannot be scrolled any farther to the right once it is displaying
-normally (with each line starting at the window's left margin);
-attempting to do so has no effect.

-
-Selective Display
-=================
-
- XEmacs can hide lines indented more than a certain number of columns
-(you specify how many columns). This allows you to get an overview of
-a part of a program.
-
- To hide lines, type `C-x $' (`set-selective-display') with a numeric
-argument N. (*Note Arguments::, for information on giving the
-argument.) Lines with at least N columns of indentation disappear from
-the screen. The only indication of their presence are three dots
-(`...'), which appear at the end of each visible line that is followed
-by one or more invisible ones.
-
- The invisible lines are still present in the buffer, and most editing
-commands see them as usual, so it is very easy to put point in the
-middle of invisible text. When this happens, the cursor appears at the
-end of the previous line, after the three dots. If point is at the end
-of the visible line, before the newline that ends it, the cursor
-appears before the three dots.
-
- The commands `C-n' and `C-p' move across the invisible lines as if
-they were not there.
-
- To make everything visible again, type `C-x $' with no argument.

-
-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.
