-.Sh NAME
-.Nm editrc
-.Nd configuration file for editline library
-.Sh SYNOPSIS
-.Nm
-.Sh DESCRIPTION
-The
-.Nm
-file defines various settings to be used by the
-.Xr editline 3
-library.
-.Pp
-The format of each line is:
-.Pp
-.Dl [prog:]command [arg ...]
-.Pp
-.Ar command
-is one of the
-.Xr editline 3
-builtin commands.
-Refer to
-.Sx BUILTIN COMMANDS
-for more information.
-.Pp
-.Ar prog
-is the program name string that a program defines when it calls
-.Xr el_init 3
-to set up
-.Xr editline 3 ,
-which is usually
-.Va argv[0] .
-.Ar command
-will be executed for any program which matches
-.Ar prog .
-.Pp
-.Ar prog
-may also be a
-.Xr regex 3
-style
-regular expression, in which case
-.Ar command
-will be executed for any program that matches the regular expression.
-.Pp
-If
-.Ar prog
-is absent,
-.Ar command
-is executed for all programs.
-.Sh BUILTIN COMMANDS
-The
-.Nm editline
-library has some builtin commands, which affect the way
-that the line editing and history functions operate.
-These are based on similar named builtins present in the
-.Xr tcsh 1
-shell.
-.Pp
-The following builtin commands are available:
-.Bl -tag -width 4n
-.It Ic bind Oo Fl aeklrsv Oc Op Ar key Op Ar command
-Without options and arguments, list all bound keys and macros, and
-the editor command or input string to which each one is bound.
-If only
-.Ar key
-is supplied, show the binding for that key or macro.
-If
-.Ar key command
-is supplied, bind the editor
-.Ar command
-to that key or macro.
-.Pp
-The options are as follows:
-.Bl -tag -width 4n
-.It Fl a
-List or change key bindings in the
-.Xr vi 1
-mode alternate (command mode) key map.
-.It Fl e
-Bind all keys to the standard GNU Emacs-like bindings.
-.It Fl k
-.Ar key
-is interpreted as a symbolic arrow key name, which may be one of
-.Sq up ,
-.Sq down ,
-.Sq left
-or
-.Sq right .
-.It Fl l
-List all editor commands and a short description of each.
-.It Fl r
-Remove the binding of the key or macro
-.Ar key .
-.It Fl s
-Define a keyboard macro rather than a key binding or command macro:
-.Ar command
-is taken as a literal string and appended to the input queue whenever
-.Ar key
-is typed.
-Bound keys and macros in
-.Ar command
-are themselves reinterpreted, and this continues for ten levels of
-interpretation.
-.It Fl v
-Bind all keys to the standard
-.Xr vi 1 Ns -like
-bindings.
-.El
-.Pp
-The
-.Xr editline 7
-manual documents all editor commands and contains more information
-about macros and the input queue.
-.Pp
-.Ar key
-and
-.Ar command
-can contain control characters of the form
-.Sm off
-.Sq No ^ Ar character
-.Sm on
-.Po
-e.g.\&
-.Sq ^A
-.Pc ,
-and the following backslashed escape sequences:
-.Pp
-.Bl -tag -compact -offset indent -width 4n
-.It Ic \ea
-Bell
-.It Ic \eb
-Backspace
-.It Ic \ee
-Escape
-.It Ic \ef
-Formfeed
-.It Ic \en
-Newline
-.It Ic \er
-Carriage return
-.It Ic \et
-Horizontal tab
-.It Ic \ev
-Vertical tab
-.Sm off
-.It Sy \e Ar nnn
-.Sm on
-The ASCII character corresponding to the octal number
-.Ar nnn .
-.El
-.Pp
-.Sq \e
-nullifies the special meaning of the following character,
-if it has any, notably
-.Sq \e
-and
-.Sq ^ .
-.It Ic echotc Oo Fl sv Oc Ar arg Ar ...
-Exercise terminal capabilities given in
-.Ar arg ... .
-If
-.Ar arg
-is
-.Sq baud ,
-.Sq cols ,
-.Sq lines ,
-.Sq rows ,
-.Sq meta ,
-or
-.Sq tabs ,
-the value of that capability is printed, with
-.Dq yes
-or
-.Dq no
-indicating that the terminal does or does not have that capability.
-.Pp
-.Fl s
-returns an empty string for non-existent capabilities, rather than
-causing an error.
-.Fl v
-causes messages to be verbose.
-.It Ic edit Op Li on | Li off
-Enable or disable the
-.Nm editline
-functionality in a program.
-.It Ic history Ar list | Ar size Dv n | Ar unique Dv n
-The
-.Ar list
-command lists all entries in the history.
-The
-.Ar size
-command sets the history size to
-.Dv n
-entries.
-The
-.Ar unique
-command controls if history should keep duplicate entries.
-If
-.Dv n
-is non zero, only keep unique history entries.
-If
-.Dv n
-is zero, then keep all entries (the default).
-.It Ic settc Ar cap Ar val
-Set the terminal capability
-.Ar cap
-to
-.Ar val ,
-as defined in
-.Xr termcap 5 .
-No sanity checking is done.
-.It Ic setty Oo Fl a Oc Oo Fl d Oc Oo Fl q Oc Oo Fl x Oc Oo Ar +mode Oc \
-Oo Ar -mode Oc Oo Ar mode Oc Oo Ar char=c Oc
-Control which tty modes that
-.Nm
-won't allow the user to change.
-.Fl d ,
-.Fl q
-or
-.Fl x
-tells
-.Ic setty
-to act on the
-.Sq edit ,
-.Sq quote
-or
-.Sq execute
-set of tty modes respectively; defaulting to
-.Fl x .
-.Pp
-Without other arguments,
-.Ic setty
-lists the modes in the chosen set which are fixed on
-.Po
-.Sq +mode
-.Pc
-or off
-.Po
-.Sq -mode
-.Pc .
-.Fl a
-lists all tty modes in the chosen set regardless of the setting.
-With
-.Ar +mode ,
-.Ar -mode
-or
-.Ar mode ,
-fixes
-.Ar mode
-on or off or removes control of
-.Ar mode
-in the chosen set.
-.Pp
-.Ic Setty
-can also be used to set tty characters to particular values using
-.Ar char=value .
-If
-.Ar value
-is empty
-then the character is set to
-.Dv _POSIX_VDISABLE .
-.It Ic telltc
-List the values of all the terminal capabilities (see
-.Xr termcap 5 ) .
