NNAAMMEE
       readline - get a line from a user with editing

NNOOTTAATTIIOONN
       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   backward  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.

IINNIITTIIAALLIIZZAATTIIOONN FFIILLEE
       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  commands
       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).


   KKeeyy BBiinnddiinnggss
       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_-  prefixes,  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 specified 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.

   VVaarriiaabblleess
       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 characters 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, scrolling 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.

   CCoonnddiittiioonnaall CCoonnssttrruuccttss
       Readline implements a facility similar in  spirit  to  the
       conditional  compilation  features  of  the C preprocessor
       which allows key bindings  and  variable  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  bindings, 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 terminal 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 command.

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

       $$iinncclluuddee
              This  directive  takes  a  single  filename  as  an
              argument and reads commands and bindings from  that
              file.   For  example, the following directive would
              read _/_e_t_c_/_i_n_p_u_t_r_c:

              $$iinncclluuddee  _/_e_t_c_/_i_n_p_u_t_r_c

SSEEAARRCCHHIINNGG
       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 incremental 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 forward 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 history 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.

EEDDIITTIINNGG CCOOMMMMAANNDDSS
       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.

              are composed of  alphanumeric  characters  (letters
              and digits).
       bbaacckkwwaarrdd--wwoorrdd ((MM--bb))
              Move  back  to the start of the current or 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.

   CCoommmmaannddss ffoorr MMaanniippuullaattiinngg tthhee HHiissttoorryy
       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 history 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.

   CCoommmmaannddss ffoorr CChhaannggiinngg TTeexxtt
       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 argument, 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.

   KKiilllliinngg aanndd YYaannkkiinngg
       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.

   NNuummeerriicc AArrgguummeennttss
       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  followed  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.

   CCoommpplleettiinngg
       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 single  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.

   KKeeyybbooaarrdd MMaaccrrooss
       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.

   MMiisscceellllaanneeoouuss
       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  (subject  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 newline 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  output  stream.   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.
       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 formatted 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

       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  insertion  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).
