  94 <P>

  96 The following paragraphs describe the notation used to represent
  97 keystrokes.
  98 </P><P>
  99
 100 The text <KBD>C-k</KBD> is read as `Control-K' and describes the character
 101 produced when the <KBD>k</KBD> key is pressed while the Control key
 102 is depressed.
 103 </P><P>
 104
 105 The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character
 106 produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD>
 107 key is pressed.
 108 The Meta key is labeled <KBD>ALT</KBD> on many keyboards.
 109 On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of
 110 the space bar), the <KBD>ALT</KBD> on the left side is generally set to
 111 work as a Meta key.
 112 The <KBD>ALT</KBD> key on the right may also be configured to work as a
 113 Meta key or may be configured as some other modifier, such as a
 114 Compose key for typing accented characters.
 115 </P><P>
 116
 117 If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as
 118 a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD>
 119 <EM>first</EM>, and then typing <KBD>k</KBD>.
 120 Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key.
 121 </P><P>
 122
 123 The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the
 124 character produced by <EM>metafying</EM> <KBD>C-k</KBD>.
 125 </P><P>
 126
 127 In addition, several keys have their own names.  Specifically,
 128 <KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all
 129 stand for themselves when seen in this text, or in an init file
 130 (see section <A HREF="rluserman.html#SEC9">1.3 Readline Init File</A>).
 131 If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will
 132 produce the desired character.
 133 The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on
 134 some keyboards.

 152 <!--docid::SEC3::-->
 153 <P>
 154
 155 Often during an interactive session you type in a long line of text,
 156 only to notice that the first word on the line is misspelled.  The
 157 Readline library gives you a set of commands for manipulating the text
 158 as you type it in, allowing you to just fix your typo, and not forcing
 159 you to retype the majority of the line.  Using these editing commands,
 160 you move the cursor to the place that needs correction, and delete or
 161 insert the text of the corrections.  Then, when you are satisfied with
 162 the line, you simply press <KBD>RET</KBD>.  You do not have to be at the
 163 end of the line to press <KBD>RET</KBD>; the entire line is accepted
 164 regardless of the location of the cursor within the line.

 192 <P>
 193
 194 In order to enter characters into the line, simply type them.  The typed
 195 character appears where the cursor was, and then the cursor moves one
 196 space to the right.  If you mistype a character, you can use your
 197 erase character to back up and delete the mistyped character.
 198 </P><P>
 199
 200 Sometimes you may mistype a character, and
 201 not notice the error until you have typed several other characters.  In
 202 that case, you can type <KBD>C-b</KBD> to move the cursor to the left, and then
 203 correct your mistake.  Afterwards, you can move the cursor to the right
 204 with <KBD>C-f</KBD>.
 205 </P><P>
 206
 207 When you add text in the middle of a line, you will notice that characters
 208 to the right of the cursor are `pushed over' to make room for the text
 209 that you have inserted.  Likewise, when you delete text behind the cursor,
 210 characters to the right of the cursor are `pulled back' to fill in the
 211 blank space created by the removal of the text.  A list of the bare
 212 essentials for editing the text of an input line follows.

 256 The above table describes the most basic keystrokes that you need
 257 in order to do editing of the input line.  For your convenience, many
 258 other commands have been added in addition to <KBD>C-b</KBD>, <KBD>C-f</KBD>,
 259 <KBD>C-d</KBD>, and <KBD>DEL</KBD>.  Here are some commands for moving more rapidly
 260 about the line.

 264 <DT><KBD>C-a</KBD>
 265 <DD>Move to the start of the line.

 269 <DD>Move forward a word, where a word is composed of letters and digits.
 270 <DT><KBD>M-b</KBD>

 276
 277 Notice how <KBD>C-f</KBD> moves forward a character, while <KBD>M-f</KBD> moves
 278 forward a word.  It is a loose convention that control keystrokes
 279 operate on characters while meta keystrokes operate on words.

 304 <EM>Killing</EM> text means to delete the text from the line, but to save
 305 it away for later use, usually by <EM>yanking</EM> (re-inserting)
 306 it back into the line.
 307 (`Cut' and `paste' are more recent jargon for `kill' and `yank'.)
 308 </P><P>
 309
 310 If the description for a command says that it `kills' text, then you can
 311 be sure that you can get the text back in a different (or the same)
 312 place later.
 313 </P><P>
 314
 315 When you use a kill command, the text is saved in a <EM>kill-ring</EM>.
 316 Any number of consecutive kills save all of the killed text together, so
 317 that when you yank it back, you get it all.  The kill
 318 ring is not line specific; the text that you killed on a previously
 319 typed line is available to be yanked back later, when you are typing
 320 another line.

 382 <!--docid::SEC7::-->
 383 <P>
 384
 385 You can pass numeric arguments to Readline commands.  Sometimes the
 386 argument acts as a repeat count, other times it is the <I>sign</I> of the
 387 argument that is significant.  If you pass a negative argument to a
 388 command which normally acts in a forward direction, that command will
 389 act in a backward direction.  For example, to kill text back to the
 390 start of the line, you might type <SAMP>`M-- C-k'</SAMP>.
 391 </P><P>
 392
 393 The general way to pass numeric arguments to a command is to type meta
 394 digits before the command.  If the first `digit' typed is a minus
 395 sign (<SAMP>`-'</SAMP>), then the sign of the argument will be negative.  Once
 396 you have typed one meta digit to get the argument started, you can type
 397 the remainder of the digits, and then the command.  For example, to give
 398 the <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>,
 399 which will delete the next ten characters on the input line.

 416 <H3> 1.2.5 Searching for Commands in the History </H3>
 417 <!--docid::SEC8::-->
 418 <P>
 419
 420 Readline provides commands for searching through the command history
 421 for lines containing a specified string.
 422 There are two search modes:  <EM>incremental</EM> and <EM>non-incremental</EM>.
 423 </P><P>
 424
 425 Incremental searches begin before the user has finished typing the
 426 search string.
 427 As each character of the search string is typed, Readline displays
 428 the next entry from the history matching the string typed so far.
 429 An incremental search requires only as many characters as needed to
 430 find the desired history entry.
 431 To search backward in the history for a particular string, type
 432 <KBD>C-r</KBD>.  Typing <KBD>C-s</KBD> searches forward through the history.
 433 The characters present in the value of the <CODE>isearch-terminators</CODE> variable
 434 are used to terminate an incremental search.
 435 If that variable has not been assigned a value, the <KBD>ESC</KBD> and
 436 <KBD>C-J</KBD> characters will terminate an incremental search.
 437 <KBD>C-g</KBD> will abort an incremental search and restore the original line.
 438 When the search is terminated, the history entry containing the
 439 search string becomes the current line.
 440 </P><P>
 441
 442 To find other matching entries in the history list, type <KBD>C-r</KBD> or
 443 <KBD>C-s</KBD> as appropriate.
 444 This will search backward or forward in the history for the next
 445 entry matching the search string typed so far.
 446 Any other key sequence bound to a Readline command will terminate
 447 the search and execute that command.
 448 For instance, a <KBD>RET</KBD> will terminate the search and accept
 449 the line, thereby executing the command from the history list.
 450 A movement command will terminate the search, make the last line found
 451 the current line, and begin editing.
 452 </P><P>
 453
 454 Readline remembers the last incremental search string.  If two
 455 <KBD>C-r</KBD>s are typed without any intervening characters defining a new
 456 search string, any remembered search string is used.
 457 </P><P>
 458
 459 Non-incremental searches read the entire search string before starting
 460 to search for matching history lines.  The search string may be
 461 typed by the user or be part of the contents of the current line.

 480 <P>
 481
 482 Although the Readline library comes with a set of Emacs-like
 483 keybindings installed by default, it is possible to use a different set
 484 of keybindings.
 485 Any user can customize programs that use Readline by putting
 486 commands in an <EM>inputrc</EM> file, conventionally in his home directory.
 487 The name of this
 488 file is taken from the value of the environment variable <CODE>INPUTRC</CODE>.  If
 489 that variable is unset, the default is <TT>`~/.inputrc'</TT>.
 490 </P><P>
 491
 492 When a program which uses the Readline library starts up, the
 493 init file is read, and the key bindings are set.
 494 </P><P>
 495
 496 In addition, the <CODE>C-x C-r</CODE> command re-reads this init file, thus
 497 incorporating any changes that you might have made to it.

 535 Lines beginning with a <SAMP>`#'</SAMP> are comments.
 536 Lines beginning with a <SAMP>`$'</SAMP> indicate conditional

 595 The number of possible completions that determines when the user is
 596 asked whether he wants to see the list of possibilities.  If the
 597 number of possible completions is greater than this value,
 598 Readline will ask the user whether or not he wishes to view
 599 them; otherwise, they are simply listed.
 600 This variable must be set to an integer value greater than or equal to 0.

 648 This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>.  Setting it
 649 to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll
 650 horizontally on a single screen line when they are longer than the width
 651 of the screen, instead of wrapping onto a new screen line.  By default,
 652 this variable is set to <SAMP>`off'</SAMP>.

 685 <CODE>vi</CODE> is equivalent to <CODE>vi-command</CODE>; <CODE>emacs</CODE> is
 686 equivalent to <CODE>emacs-standard</CODE>.  The default value is <CODE>emacs</CODE>.

 711 <DT><CODE>match-hidden-files</CODE>
 712 <DD><A NAME="IDX21"></A>
 713 This variable, when set to <SAMP>`on'</SAMP>, causes Readline to match files whose
 714 names begin with a <SAMP>`.'</SAMP> (hidden files) when performing filename
 715 completion, unless the leading <SAMP>`.'</SAMP> is
 716 supplied by the user in the filename to be completed.

 724 sequence.  The default is <SAMP>`off'</SAMP>.
 725 <P>
 726
 727 <DT><CODE>page-completions</CODE>
 728 <DD><A NAME="IDX23"></A>
 729 If set to <SAMP>`on'</SAMP>, Readline uses an internal <CODE>more</CODE>-like pager
 730 to display a screenful of possible completions at a time.
 731 This variable is <SAMP>`on'</SAMP> by default.
 732 <P>
 733
 734 <DT><CODE>print-completions-horizontally</CODE>
 735 <DD>If set to <SAMP>`on'</SAMP>, Readline will display completions with matches
 736 sorted horizontally in alphabetical order, rather than down the screen.
 737 The default is <SAMP>`off'</SAMP>.
 738 <P>
 739
 740 <DT><CODE>show-all-if-ambiguous</CODE>
 741 <DD><A NAME="IDX24"></A>
 742 This alters the default behavior of the completion functions.  If
 743 set to <SAMP>`on'</SAMP>,
 744 words which have more than one possible completion cause the
 745 matches to be listed immediately instead of ringing the bell.
 746 The default value is <SAMP>`off'</SAMP>.
 747 <P>
 748
 749 <DT><CODE>visible-stats</CODE>
 750 <DD><A NAME="IDX25"></A>
 751 If set to <SAMP>`on'</SAMP>, a character denoting a file's type

 759 <DT>Key Bindings
 760 <DD>The syntax for controlling key bindings in the init file is
 761 simple.  First you need to find the name of the command that you

 763 name, the default keybinding, if any, and a short description of what
 764 the command does.
 765 <P>
 766
 767 Once you know the name of the command, simply place on a line
 768 in the init file the name of the key
 769 you wish to bind the command to, a colon, and then the name of the
 770 command.  The name of the key
 771 can be expressed in different ways, depending on what you find most
 772 comfortable.
 773 </P><P>

 780 <DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR>
 781 <DD><VAR>keyname</VAR> is the name of a key spelled out in English.  For example:

 912 <H3> 1.3.2 Conditional Init Constructs </H3>
 913 <!--docid::SEC11::-->
 914 <P>
 915
 916 Readline implements a facility similar in spirit to the conditional
 917 compilation features of the C preprocessor which allows key
 918 bindings and variable settings to be performed as the result
 919 of tests.  There are four parser directives used.
 920 </P><P>
 921
 922 <DL COMPACT>
 923 <DT><CODE>$if</CODE>
 924 <DD>The <CODE>$if</CODE> construct allows bindings to be made based on the
 925 editing mode, the terminal being used, or the application using
 926 Readline.  The text of the test extends to the end of the line;
 927 no characters are required to isolate it.
 928 <P>
 929
 930 <DL COMPACT>
 931 <DT><CODE>mode</CODE>
 932 <DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test
 933 whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode.
 934 This may be used in conjunction
 935 with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in
 936 the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if
 937 Readline is starting out in <CODE>emacs</CODE> mode.
 938 <P>
 939
 940 <DT><CODE>term</CODE>
 941 <DD>The <CODE>term=</CODE> form may be used to include terminal-specific
 942 key bindings, perhaps to bind the key sequences output by the
 943 terminal's function keys.  The word on the right side of the
 944 <SAMP>`='</SAMP> is tested against both the full name of the terminal and
 945 the portion of the terminal name before the first <SAMP>`-'</SAMP>.  This
 946 allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>,
 947 for instance.
 948 <P>
 949
 950 <DT><CODE>application</CODE>
 951 <DD>The <VAR>application</VAR> construct is used to include
 952 application-specific settings.  Each program using the Readline
 953 library sets the <VAR>application name</VAR>, and you can test for
 954 a particular value.
 955 This could be used to bind key sequences to functions useful for
 956 a specific program.  For instance, the following command adds a
 957 key sequence that quotes the current or previous word in Bash:
 958 <TABLE><tr><td>&nbsp;</td><td class=example><pre>$if Bash
 959 # Quote the current or previous word
 960 "\C-xq": "\eb\"\ef\""
 961 $endif
 962 </pre></td></tr></table></DL>
 963 <P>
 964
 965 <DT><CODE>$endif</CODE>
 966 <DD>This command, as seen in the previous example, terminates an
 967 <CODE>$if</CODE> command.
 968 <P>
 969
 970 <DT><CODE>$else</CODE>
 971 <DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if
 972 the test fails.
 973 <P>
 974
 975 <DT><CODE>$include</CODE>
 976 <DD>This directive takes a single filename as an argument and reads commands
 977 and bindings from that file.
 978 For example, the following directive reads from <TT>`/etc/inputrc'</TT>:
 979 <TABLE><tr><td>&nbsp;</td><td class=example><pre>$include /etc/inputrc
 980 </pre></td></tr></table></DL>

1408 <DD><A NAME="IDX81"></A>
1409 Drag the character before the cursor forward over
1410 the character at the cursor, moving the
1411 cursor forward as well.  If the insertion point
1412 is at the end of the line, then this
1413 transposes the last two characters of the line.
1414 Negative arguments have no effect.
1415 <P>
1416
1417 <A NAME="IDX82"></A>
1418 <DT><CODE>transpose-words (M-t)</CODE>
1419 <DD><A NAME="IDX83"></A>
1420 Drag the word before point past the word after point,
1421 moving point past that word as well.
1422 If the insertion point is at the end of the line, this transposes
1423 the last two words on the line.

1446
1447 <A NAME="IDX90"></A>
1448 <DT><CODE>overwrite-mode ()</CODE>
1449 <DD><A NAME="IDX91"></A>
1450 Toggle overwrite mode.  With an explicit positive numeric argument,
1451 switches to overwrite mode.  With an explicit non-positive numeric
1452 argument, switches to insert mode.  This command affects only
1453 <CODE>emacs</CODE> mode; <CODE>vi</CODE> mode does overwrite differently.
1454 Each call to <CODE>readline()</CODE> starts in insert mode.
1455 <P>
1456
1457 In overwrite mode, characters bound to <CODE>self-insert</CODE> replace
1458 the text at point rather than pushing the text to the right.
1459 Characters bound to <CODE>backward-delete-char</CODE> replace the character
1460 before point with a space.

1614 This is another way to specify an argument.
1615 If this command is followed by one or more digits, optionally with a
1616 leading minus sign, those digits define the argument.
1617 If the command is followed by digits, executing <CODE>universal-argument</CODE>
1618 again ends the numeric argument, but is otherwise ignored.
1619 As a special case, if this command is immediately followed by a
1620 character that is neither a digit or minus sign, the argument count
1621 for the next command is multiplied by four.
1622 The argument count is initially one, so executing this function the
1623 first time makes the argument count four, a second time makes the

1910
1911 While the Readline library does not have a full set of <CODE>vi</CODE>
1912 editing functions, it does contain enough to allow simple editing
1913 of the line.  The Readline <CODE>vi</CODE> mode behaves as specified in
1914 the POSIX 1003.2 standard.
1915 </P><P>
1916
1917 In order to switch interactively between <CODE>emacs</CODE> and <CODE>vi</CODE>
1918 editing modes, use the command <KBD>M-C-j</KBD> (bound to emacs-editing-mode
1919 when in <CODE>vi</CODE> mode and to vi-editing-mode in <CODE>emacs</CODE> mode).
1920 The Readline default is <CODE>emacs</CODE> mode.
1921 </P><P>
1922
1923 When you enter a line in <CODE>vi</CODE> mode, you are already placed in
1924 `insertion' mode, as if you had typed an <SAMP>`i'</SAMP>.  Pressing <KBD>ESC</KBD>
1925 switches you into `command' mode, where you can edit the text of the
1926 line with the standard <CODE>vi</CODE> movement keys, move to previous
1927 history lines with <SAMP>`k'</SAMP> and subsequent lines with <SAMP>`j'</SAMP>, and
1928 so forth.
