NAME
  readline - get a line from a user with editing

NOTATION

  An emacs-style notation is used to denote keystrokes.  Control keys are
  denoted by C-_k_e_y, e.g., C-n means Control-N.  Similarly, _m_e_t_a keys are
  denoted by M-_k_e_y, so M-x means Meta-X.  (On keyboards without a _m_e_t_a key,
  M-_x means ESC _x, i.e., press the Escape key then the _x key.  This makes ESC
  the _m_e_t_a _p_r_e_f_i_x.  The combination M-C-_x means ESC-Control-_x, or press the
  Escape key then hold the Control key while pressing the _x key.)

  Readline commands may be given numeric _a_r_g_u_m_e_n_t_s, which normally act as a
  repeat count.  Sometimes, however, it is the sign of the argument that is
  significant.  Passing a negative argument to a command that acts in the
  forward direction (e.g., kkiillll--lliinnee) causes that command to act in a back-
  ward direction.  Commands whose behavior with arguments deviates from this
  are noted.

  When a command is described as _k_i_l_l_i_n_g text, the text deleted is saved for
  possible future retrieval (_y_a_n_k_i_n_g).  The killed text is saved in a _k_i_l_l
  _r_i_n_g.  Consecutive kills cause the text to be accumulated into one unit,
  which can be yanked all at once. Commands which do not kill text separate
  the chunks of text on the kill ring.

INITIALIZATION FILE

  Readline is customized by putting commands in an initialization file (the
  _i_n_p_u_t_r_c file).  The name of this file is taken from the value of the
  IINNPPUUTTRRCC environment variable.  If that variable is unset, the default is
  ~/._i_n_p_u_t_r_c.  When a program which uses the readline library starts up, the
  init file is read, and the key bindings and variables are set.  There are
  only a few basic constructs allowed in the readline init file.  Blank lines
  are ignored.  Lines beginning with a ## are comments.  Lines beginning with
  a $$ indicate conditional constructs.  Other lines denote key bindings and
  variable settings.  Each program using this library may add its own com-
  mands and bindings.

  For example, placing

       M-Control-u: universal-argument
  or
       C-Meta-u: universal-argument
  into the _i_n_p_u_t_r_c would make M-C-u execute the readline command
  _u_n_i_v_e_r_s_a_l-_a_r_g_u_m_e_n_t.

  The following symbolic character names are recognized while processing key
  bindings: _R_U_B_O_U_T, _D_E_L, _E_S_C, _L_F_D, _N_E_W_L_I_N_E, _R_E_T, _R_E_T_U_R_N, _S_P_C, _S_P_A_C_E, and _T_A_B.
  In addition to command names, readline allows keys to be bound to a string
  that is inserted when the key is pressed (a _m_a_c_r_o).



  Key Bindings


  The syntax for controlling key bindings in the _i_n_p_u_t_r_c file is simple.  All
  that is required is the name of the command or the text of a macro and a
  key sequence to which it should be bound. The name may be specified in one
  of two ways: as a symbolic key name, possibly with _M_e_t_a- or _C_o_n_t_r_o_l- pre-
  fixes, or as a key sequence.  When using the form kkeeyynnaammee:_f_u_n_c_t_i_o_n-_n_a_m_e or
  _m_a_c_r_o, _k_e_y_n_a_m_e is the name of a key spelled out in English.  For example:

       Control-u: universal-argument
       Meta-Rubout: backward-kill-word
       Control-o: ">&output"

  In the above example, _C-_u is bound to the function uunniivveerrssaall--aarrgguummeenntt, _M-
  _D_E_L is bound to the function bbaacckkwwaarrdd--kkiillll--wwoorrdd, and _C-_o is bound to run
  the macro expressed on the right hand side (that is, to insert the text
  >&_o_u_t_p_u_t into the line).

  In the second form, ""kkeeyysseeqq"":_f_u_n_c_t_i_o_n-_n_a_m_e or _m_a_c_r_o, kkeeyysseeqq differs from
  kkeeyynnaammee above in that strings denoting an entire key sequence may be speci-
  fied by placing the sequence within double quotes.  Some GNU Emacs style
  key escapes can be used, as in the following example.

       "\C-u": universal-argument
       "\C-x\C-r": re-read-init-file
       "\e[11~": "Function Key 1"

  In this example, _C-_u is again bound to the function uunniivveerrssaall--aarrgguummeenntt.
  _C-_x _C-_r is bound to the function rree--rreeaadd--iinniitt--ffiillee, and _E_S_C [ _1 _1 ~ is
  bound to insert the text FFuunnccttiioonn KKeeyy 11.  The full set of GNU Emacs style
  escape sequences is
       \\CC--
         control prefix
       \\MM--
         meta prefix
       \\ee
         an escape character
       \\\\
         backslash
       \\""
         literal "
       \\''
         literal '

  In addition to the GNU Emacs style escape sequences, a second set of
  backslash escapes is available:
       \\aa
         alert (bell)
       \\bb
         backspace
       \\dd
         delete
       \\ff
         form feed
       \\nn
         newline
       \\rr
         carriage return
       \\tt
         horizontal tab
       \\vv
         vertical tab
       \\_n_n_n
         the character whose ASCII code is the octal value _n_n_n (one to three
         digits)
       \\xx_n_n_n
         the character whose ASCII code is the hexadecimal value _n_n_n (one to
         three digits)

  When entering the text of a macro, single or double quotes should be used
  to indicate a macro definition.  Unquoted text is assumed to be a function
  name.  In the macro body, the backslash escapes described above are
  expanded.  Backslash will quote any other character in the macro text,
  including " and '.

  BBaasshh allows the current readline key bindings to be displayed or modified
  with the bbiinndd builtin command.  The editing mode may be switched during
  interactive use by using the --oo option to the sseett builtin command.  Other
  programs using this library provide similar mechanisms.  The _i_n_p_u_t_r_c file
  may be edited and re-read if a program does not provide any other means to
  incorporate new bindings.

  Variables


  Readline has variables that can be used to further customize its behavior.
  A variable may be set in the _i_n_p_u_t_r_c file with a statement of the form

       sseett _v_a_r_i_a_b_l_e-_n_a_m_e _v_a_l_u_e

  Except where noted, readline variables can take the values OOnn or OOffff.  The
  variables and their default values are:

  bbeellll--ssttyyllee ((aauuddiibbllee))
       Controls what happens when readline wants to ring the terminal bell.
       If set to nnoonnee, readline never rings the bell.  If set to vviissiibbllee,
       readline uses a visible bell if one is available.  If set to aauuddiibbllee,
       readline attempts to ring the terminal's bell.
  ccoommmmeenntt--bbeeggiinn ((````;;''''))
       The string that is inserted in vvii mode when the iinnsseerrtt--ccoommmmeenntt command
       is executed.  This command is bound to MM--## in emacs mode and to ## in
       vi command mode.
  ccoommpplleettiioonn--iiggnnoorree--ccaassee ((OOffff))
       If set to OOnn, readline performs filename matching and completion in a
       case-insensitive fashion.
  bblliinnkk--mmaattcchhiinngg--ppaarreenn ((OOnn))
       If set to OOnn, readline will display the corresponding opening
       parenthesis when a closing parenthesis is typed.
  ccoommpplleettiioonn--qquueerryy--iitteemmss ((110000))
       This determines when the user is queried about viewing the number of
       possible completions generated by the ppoossssiibbllee--ccoommpplleettiioonnss command.
       It may be set to any integer value greater than or equal to zero.  If
       the number of possible completions is greater than or equal to the
       value of this variable, the user is asked whether or not he wishes to
       view them; otherwise they are simply listed on the terminal.
  ddiissaabbllee--ccoommpplleettiioonn ((OOffff))
       If set to OOnn, readline will inhibit word completion.  Completion char-
       acters will be inserted into the line as if they had been mapped to
       sseellff--iinnsseerrtt.
  eeddiittiinngg--mmooddee ((eemmaaccss))
       Controls whether readline begins with a set of key bindings similar to
       _e_m_a_c_s or _v_i.  eeddiittiinngg--mmooddee can be set to either eemmaaccss or vvii.
  eennaabbllee--kkeeyyppaadd ((OOffff))
       When set to OOnn, readline will try to enable the application keypad
       when it is called.  Some systems need this to enable the arrow keys.
  eexxppaanndd--ttiillddee ((OOffff))
       If set to oonn, tilde expansion is performed when readline attempts word
       completion.
  hhoorriizzoonnttaall--ssccrroollll--mmooddee ((OOffff))
       When set to OOnn, makes readline use a single line for display, scrol-
       ling the input horizontally on a single screen line when it becomes
       longer than the screen width rather than wrapping to a new line.
  kkeeyymmaapp ((eemmaaccss))
       Set the current readline keymap.  The set of legal keymap names is
       _e_m_a_c_s, _e_m_a_c_s-_s_t_a_n_d_a_r_d, _e_m_a_c_s-_m_e_t_a, _e_m_a_c_s-_c_t_l_x, _v_i, _v_i-_m_o_v_e, _v_i-
       _c_o_m_m_a_n_d, and _v_i-_i_n_s_e_r_t.  _v_i is equivalent to _v_i-_c_o_m_m_a_n_d; _e_m_a_c_s is
       equivalent to _e_m_a_c_s-_s_t_a_n_d_a_r_d.  The default value is _e_m_a_c_s; the value
       of eeddiittiinngg--mmooddee also affects the default keymap.
  mmaarrkk--ddiirreeccttoorriieess ((OOnn))
       If set to OOnn, completed directory names have a slash appended.
  mmaarrkk--mmooddiiffiieedd--lliinneess ((OOffff))
       If set to OOnn, history lines that have been modified are displayed with
       a preceding asterisk (**).
  ccoonnvveerrtt--mmeettaa ((OOnn))
       If set to OOnn, readline will convert characters with the eighth bit set
       to an ASCII key sequence by stripping the eighth bit and prepending an
       escape character (in effect, using escape as the _m_e_t_a _p_r_e_f_i_x).
  mmeettaa--ffllaagg ((OOffff))
       If set to OOnn, readline will enable eight-bit input (that is, it will
       not strip the high bit from the characters it reads), regardless of
       what the terminal claims it can support.
  oouuttppuutt--mmeettaa ((OOffff))
       If set to OOnn, readline will display characters with the eighth bit set
       directly rather than as a meta-prefixed escape sequence.
  pprriinntt--ccoommpplleettiioonnss--hhoorriizzoonnttaallllyy ((OOffff))
       If set to OOnn, readline will display completions with matches sorted
       horizontally in alphabetical order, rather than down the screen.
  sshhooww--aallll--iiff--aammbbiigguuoouuss ((OOffff))
       This alters the default behavior of the completion functions.  If set
       to oonn, words which have more than one possible completion cause the
       matches to be listed immediately instead of ringing the bell.
  vviissiibbllee--ssttaattss ((OOffff))
       If set to OOnn, a character denoting a file's type as reported by
       ssttaatt(2) is appended to the filename when listing possible completions.

  Conditional Constructs


  Readline implements a facility similar in spirit to the conditional compi-
  lation features of the C preprocessor which allows key bindings and vari-
  able settings to be performed as the result of tests.  There are four
  parser directives used.

  $$iiff  The $$iiff construct allows bindings to be made based on the editing
       mode, the terminal being used, or the application using readline.  The
       text of the test extends to the end of the line; no characters are
       required to isolate it.

       mmooddee
         The mmooddee== form of the $$iiff directive is used to test whether readline
         is in emacs or vi mode.  This may be used in conjunction with the
         sseett kkeeyymmaapp command, for instance, to set bindings in the _e_m_a_c_s-
         _s_t_a_n_d_a_r_d and _e_m_a_c_s-_c_t_l_x keymaps only if readline is starting out in
         emacs mode.

       tteerrmm
         The tteerrmm== form may be used to include terminal-specific key bind-
         ings, perhaps to bind the key sequences output by the terminal's
         function keys.  The word on the right side of the == is tested
         against the full name of the terminal and the portion of the termi-
         nal name before the first --.  This allows _s_u_n to match both _s_u_n and
         _s_u_n-_c_m_d, for instance.

       aapppplliiccaattiioonn
         The aapppplliiccaattiioonn construct is used to include application-specific
         settings.  Each program using the readline library sets the _a_p_p_l_i_c_a_-
         _t_i_o_n _n_a_m_e, and an initialization file can test for a particular
         value.  This could be used to bind key sequences to functions useful
         for a specific program.  For instance, the following command adds a
         key sequence that quotes the current or previous word in Bash:

         $$iiff bash
         # Quote the current or previous word
         "\C-xq": "\eb\"\ef\""
         $$eennddiiff

  $$eennddiiff
       This command, as seen in the previous example, terminates an $$iiff com-
       mand.

  $$eellssee
       Commands in this branch of the $$iiff directive are executed if the test
       fails.

  $$iinncclluuddee
       This directive takes a single filename as an argument and reads com-
       mands and bindings from that file.  For example, the following direc-
       tive would read /_e_t_c/_i_n_p_u_t_r_c:

       $$iinncclluuddee  /_e_t_c/_i_n_p_u_t_r_c

SEARCHING

  Readline provides commands for searching through the command history for
  lines containing a specified string.  There are two search modes: _i_n_c_r_e_m_e_n_-
  _t_a_l and _n_o_n-_i_n_c_r_e_m_e_n_t_a_l.

  Incremental searches begin before the user has finished typing the search
  string.  As each character of the search string is typed, readline displays
  the next entry from the history matching the string typed so far.  An
  incremental search requires only as many characters as needed to find the
  desired history entry.  The Escape character is used to terminate an incre-
  mental search.  Control-J will also terminate the search.  Control-G will
  abort an incremental search and restore the original line.  When the search
  is terminated, the history entry containing the search string becomes the
  current line.  To find other matching entries in the history list, type
  Control-S or Control-R as appropriate.  This will search backward or for-
  ward in the history for the next line matching the search string typed so
  far.  Any other key sequence bound to a readline command will terminate the
  search and execute that command.  For instance, a _n_e_w_l_i_n_e will terminate
  the search and accept the line, thereby executing the command from the his-
  tory list.

  Non-incremental searches read the entire search string before starting to
  search for matching history lines.  The search string may be typed by the
  user or be part of the contents of the current line.

EDITING COMMANDS

  The following is a list of the names of the commands and the default key
  sequences to which they are bound.  Command names without an accompanying
  key sequence are unbound by default.

  Commands for Moving


  bbeeggiinnnniinngg--ooff--lliinnee ((CC--aa))
       Move to the start of the current line.
  eenndd--ooff--lliinnee ((CC--ee))
       Move to the end of the line.
  ffoorrwwaarrdd--cchhaarr ((CC--ff))
       Move forward a character.
  bbaacckkwwaarrdd--cchhaarr ((CC--bb))
       Move back a character.
  ffoorrwwaarrdd--wwoorrdd ((MM--ff))

       alphanumeric characters (letters and digits).
  bbaacckkwwaarrdd--wwoorrdd ((MM--bb))
       Move back to the start of this, or the previous, word.  Words are
       composed of alphanumeric characters (letters and digits).
  cclleeaarr--ssccrreeeenn ((CC--ll))
       Clear the screen leaving the current line at the top of the screen.
       With an argument, refresh the current line without clearing the
       screen.
  rreeddrraaww--ccuurrrreenntt--lliinnee
       Refresh the current line.

  Commands for Manipulating the History


  aacccceepptt--lliinnee ((NNeewwlliinnee,, RReettuurrnn))
       Accept the line regardless of where the cursor is.  If this line is
       non-empty, add it to the history list. If the line is a modified his-
       tory line, then restore the history line to its original state.
  pprreevviioouuss--hhiissttoorryy ((CC--pp))
       Fetch the previous command from the history list, moving back in the
       list.
  nneexxtt--hhiissttoorryy ((CC--nn))
       Fetch the next command from the history list, moving forward in the
       list.
  bbeeggiinnnniinngg--ooff--hhiissttoorryy ((MM--<<))
       Move to the first line in the history.
  eenndd--ooff--hhiissttoorryy ((MM-->>))
       Move to the end of the input history, i.e., the line currently being
       entered.
  rreevveerrssee--sseeaarrcchh--hhiissttoorryy ((CC--rr))
       Search backward starting at the current line and moving `up' through
       the history as necessary.  This is an incremental search.
  ffoorrwwaarrdd--sseeaarrcchh--hhiissttoorryy ((CC--ss))
       Search forward starting at the current line and moving `down' through
       the history as necessary.  This is an incremental search.
  nnoonn--iinnccrreemmeennttaall--rreevveerrssee--sseeaarrcchh--hhiissttoorryy ((MM--pp))
       Search backward through the history starting at the current line using
       a non-incremental search for a string supplied by the user.
  nnoonn--iinnccrreemmeennttaall--ffoorrwwaarrdd--sseeaarrcchh--hhiissttoorryy ((MM--nn))
       Search forward through the history using a non-incremental search for
       a string supplied by the user.
  hhiissttoorryy--sseeaarrcchh--ffoorrwwaarrdd
       Search forward through the history for the string of characters
       between the start of the current line and the current cursor position
       (the _p_o_i_n_t).  This is a non-incremental search.
  hhiissttoorryy--sseeaarrcchh--bbaacckkwwaarrdd
       Search backward through the history for the string of characters
       between the start of the current line and the point.  This is a non-
       incremental search.
  yyaannkk--nntthh--aarrgg ((MM--CC--yy))
       Insert the first argument to the previous command (usually the second
       word on the previous line) at point (the current cursor position).
       With an argument _n, insert the _nth word from the previous command (the
       words in the previous command begin with word 0).  A negative argument
       inserts the _nth word from the end of the previous command.
  yyaannkk--llaasstt--aarrgg ((MM--..,, MM--__))
       Insert the last argument to the previous command (the last word of the
       previous history entry).  With an argument, behave exactly like
       yyaannkk--nntthh--aarrgg.  Successive calls to yyaannkk--llaasstt--aarrgg move back through the
       history list, inserting the last argument of each line in turn.



  Commands for Changing Text


  ddeelleettee--cchhaarr ((CC--dd))
       Delete the character under the cursor.  If point is at the beginning
       of the line, there are no characters in the line, and the last
       character typed was not bound to ddeelleettee--cchhaarr, then return EEOOFF.
  bbaacckkwwaarrdd--ddeelleettee--cchhaarr ((RRuubboouutt))
       Delete the character behind the cursor.  When given a numeric argu-
       ment, save the deleted text on the kill ring.
  qquuootteedd--iinnsseerrtt ((CC--qq,, CC--vv))
       Add the next character that you type to the line verbatim.  This is
       how to insert characters like CC--qq, for example.
  ttaabb--iinnsseerrtt ((MM--TTAABB))
       Insert a tab character.
  sseellff--iinnsseerrtt ((aa,, bb,, AA,, 11,, !!,, ......))
       Insert the character typed.
  ttrraannssppoossee--cchhaarrss ((CC--tt))
       Drag the character before point forward over the character at point.
       Point moves forward as well.  If point is at the end of the line, then
       transpose the two characters before point.  Negative arguments don't
       work.
  ttrraannssppoossee--wwoorrddss ((MM--tt))
       Drag the word behind the cursor past the word in front of the cursor
       moving the cursor over that word as well.
  uuppccaassee--wwoorrdd ((MM--uu))
       Uppercase the current (or following) word.  With a negative argument,
       uppercase the previous word, but do not move point.
  ddoowwnnccaassee--wwoorrdd ((MM--ll))
       Lowercase the current (or following) word.  With a negative argument,
       lowercase the previous word, but do not move point.
  ccaappiittaalliizzee--wwoorrdd ((MM--cc))
       Capitalize the current (or following) word.  With a negative argument,
       capitalize the previous word, but do not move point.

  Killing and Yanking


  kkiillll--lliinnee ((CC--kk))
       Kill the text from the current cursor position to the end of the line.
  bbaacckkwwaarrdd--kkiillll--lliinnee ((CC--xx RRuubboouutt))
       Kill backward to the beginning of the line.
  uunniixx--lliinnee--ddiissccaarrdd ((CC--uu))
       Kill backward from point to the beginning of the line.  The killed
       text is saved on the kill-ring.
  kkiillll--wwhhoollee--lliinnee
       Kill all characters on the current line, no matter where the cursor
       is.
  kkiillll--wwoorrdd ((MM--dd))
       Kill from the cursor to the end of the current word, or if between
       words, to the end of the next word.  Word boundaries are the same as
       those used by ffoorrwwaarrdd--wwoorrdd.
  bbaacckkwwaarrdd--kkiillll--wwoorrdd ((MM--RRuubboouutt))
       Kill the word behind the cursor.  Word boundaries are the same as
       those used by bbaacckkwwaarrdd--wwoorrdd.
  uunniixx--wwoorrdd--rruubboouutt ((CC--ww))
       Kill the word behind the cursor, using white space as a word boundary.
       The word boundaries are different from bbaacckkwwaarrdd--kkiillll--wwoorrdd.
  ddeelleettee--hhoorriizzoonnttaall--ssppaaccee ((MM--\\))
       Delete all spaces and tabs around point.
  kkiillll--rreeggiioonn
       Kill the text between the point and _m_a_r_k (saved cursor position).
       This text is referred to as the _r_e_g_i_o_n.
  ccooppyy--rreeggiioonn--aass--kkiillll
       Copy the text in the region to the kill buffer.
  ccooppyy--bbaacckkwwaarrdd--wwoorrdd
       Copy the word before point to the kill buffer.  The word boundaries
       are the same as bbaacckkwwaarrdd--wwoorrdd.
  ccooppyy--ffoorrwwaarrdd--wwoorrdd
       Copy the word following point to the kill buffer.  The word boundaries
       are the same as ffoorrwwaarrdd--wwoorrdd.
  yyaannkk ((CC--yy))
       Yank the top of the kill ring into the buffer at the cursor.
  yyaannkk--ppoopp ((MM--yy))
       Rotate the kill ring, and yank the new top.  Only works following yyaannkk
       or yyaannkk--ppoopp.

  Numeric Arguments


  ddiiggiitt--aarrgguummeenntt ((MM--00,, MM--11,, ......,, MM----))
       Add this digit to the argument already accumulating, or start a new
       argument.  M-- starts a negative argument.
  uunniivveerrssaall--aarrgguummeenntt
       This is another way to specify an argument.  If this command is fol-
       lowed by one or more digits, optionally with a leading minus sign,
       those digits define the argument.  If the command is followed by
       digits, executing uunniivveerrssaall--aarrgguummeenntt again ends the numeric argument,
       but is otherwise ignored.  As a special case, if this command is
       immediately followed by a character that is neither a digit or minus
       sign, the argument count for the next command is multiplied by four.
       The argument count is initially one, so executing this function the
       first time makes the argument count four, a second time makes the
       argument count sixteen, and so on.

  Completing


  ccoommpplleettee ((TTAABB))
       Attempt to perform completion on the text before point.  The actual
       completion performed is application-specific.  CClliisspp, for instance,
       attempts completion of symbol names, of function names (if the text is
       prefixed by (( or ##'') or of filenames (if the text is prefixed by ##"").
       BBaasshh, on the other hand, attempts completion treating the text as a
       variable (if the text begins with $$), username (if the text begins
       with ~~), hostname (if the text begins with @@), or command (including
       aliases and functions) in turn.  If none of these produces a match,
       filename completion is attempted.  GGddbb, finally, allows completion of
       program functions and variables, and only attempts filename completion
       under certain circumstances.
  ppoossssiibbllee--ccoommpplleettiioonnss ((MM--??))
       List the possible completions of the text before point.
  iinnsseerrtt--ccoommpplleettiioonnss ((MM--**))
       Insert all completions of the text before point that would have been
       generated by ppoossssiibbllee--ccoommpplleettiioonnss.
  mmeennuu--ccoommpplleettee
       Similar to ccoommpplleettee, but replaces the word to be completed with a sin-
       gle match from the list of possible completions.  Repeated execution
       of mmeennuu--ccoommpplleettee steps through the list of possible completions,
       inserting each match in turn.  At the end of the list of completions,
       the bell is rung and the original text is restored.  An argument of _n
       moves _n positions forward in the list of matches; a negative argument
       may be used to move backward through the list.  This command is
       intended to be bound to TTAABB, but is unbound by default.

  Keyboard Macros


  ssttaarrtt--kkbbdd--mmaaccrroo ((CC--xx (())
       Begin saving the characters typed into the current keyboard macro.
  eenndd--kkbbdd--mmaaccrroo ((CC--xx ))))
       Stop saving the characters typed into the current keyboard macro and
       store the definition.
  ccaallll--llaasstt--kkbbdd--mmaaccrroo ((CC--xx ee))
       Re-execute the last keyboard macro defined, by making the characters
       in the macro appear as if typed at the keyboard.


  Miscellaneous


  rree--rreeaadd--iinniitt--ffiillee ((CC--xx CC--rr))
       Read in the contents of the _i_n_p_u_t_r_c file, and incorporate any bindings
       or variable assignments found there.
  aabboorrtt ((CC--gg))
       Abort the current editing command and ring the terminal's bell (sub-
       ject to the setting of bbeellll--ssttyyllee).
  ddoo--uuppppeerrccaassee--vveerrssiioonn ((MM--aa,, MM--bb,, MM--_x,, ......))
       If the metafied character _x is lowercase, run the command that is
       bound to the corresponding uppercase character.
  pprreeffiixx--mmeettaa ((EESSCC))
       Metafy the next character typed.  EESSCC ff is equivalent to MMeettaa--ff.
  uunnddoo ((CC--__,, CC--xx CC--uu))
       Incremental undo, separately remembered for each line.
  rreevveerrtt--lliinnee ((MM--rr))
       Undo all changes made to this line.  This is like executing the uunnddoo
       command enough times to return the line to its initial state.
  ttiillddee--eexxppaanndd ((MM--~~))
       Perform tilde expansion on the current word.
  sseett--mmaarrkk ((CC--@@,, MM--<<ssppaaccee>>))
       Set the mark to the current point.  If a numeric argument is supplied,
       the mark is set to that position.
  eexxcchhaannggee--ppooiinntt--aanndd--mmaarrkk ((CC--xx CC--xx))
       Swap the point with the mark.  The current cursor position is set to
       the saved position, and the old cursor position is saved as the mark.
  cchhaarraacctteerr--sseeaarrcchh ((CC--]]))
       A character is read and point is moved to the next occurrence of that
       character.  A negative count searches for previous occurrences.
  cchhaarraacctteerr--sseeaarrcchh--bbaacckkwwaarrdd ((MM--CC--]]))
       A character is read and point is moved to the previous occurrence of
       that character.  A negative count searches for subsequent occurrences.
  iinnsseerrtt--ccoommmmeenntt ((MM--##))
       The value of the readline ccoommmmeenntt--bbeeggiinn variable is inserted at the
       beginning of the current line, and the line is accepted as if a new-
       line had been typed.  This makes the current line a shell comment.
  dduummpp--ffuunnccttiioonnss
       Print all of the functions and their key bindings to the readline out-
       put stream.  If a numeric argument is supplied, the output is format-
       ted in such a way that it can be made part of an _i_n_p_u_t_r_c file.
  dduummpp--vvaarriiaabblleess
       Print all of the settable variables and their values to the readline
       output stream.  If a numeric argument is supplied, the output is for-
       matted in such a way that it can be made part of an _i_n_p_u_t_r_c file.
  dduummpp--mmaaccrrooss
       Print all of the readline key sequences bound to macros and the
       strings they ouput.  If a numeric argument is supplied, the output is
       formatted in such a way that it can be made part of an _i_n_p_u_t_r_c file.
  eemmaaccss--eeddiittiinngg--mmooddee ((CC--ee))
       When in vvii editing mode, this causes a switch to eemmaaccss editing mode.
  vvii--eeddiittiinngg--mmooddee ((MM--CC--jj))
       When in eemmaaccss editing mode, this causes a switch to vvii editing mode.

DEFAULT KEY BINDINGS

  The following is a list of the default emacs and vi bindings.  Characters
  with the 8th bit set are written as M-<character>, and are referred to as
  _m_e_t_a_f_i_e_d characters.  The printable ASCII characters not mentioned in the
  list of emacs standard bindings are bound to the _s_e_l_f-_i_n_s_e_r_t function,
  which just inserts the given character into the input line.  In vi inser-
  tion mode, all characters not specifically mentioned are bound to
  _s_e_l_f-_i_n_s_e_r_t.  Characters assigned to signal generation by _s_t_t_y(1) or the
  terminal driver, such as C-Z or C-C, retain that function.  Upper and lower
  case _m_e_t_a_f_i_e_d characters are bound to the same function in the emacs mode
  meta keymap.  The remaining characters are unbound, which causes readline
  to ring the bell (subject to the setting of the bbeellll--ssttyyllee variable).
