Subject: Rename catsh to 1sh

Yes it's another rename because I felt like catsh was too long. 1sh is
short and unique.

-.Dt EDITLINE 7
-.Os
-.Sh NAME
-.Nm editline
-.Nd line editing user interface
-.Sh DESCRIPTION
-When a program using the
-.Xr editline 3
-library prompts for an input string using the function
-.Xr el_wgets 3 ,
-it reads characters from the terminal.
-Invalid input bytes that do not form characters are silently
-discarded.
-For each character read, one editor command is executed.
-The mapping of input characters to editor commands depends on the
-editing mode.
-There are three editing modes: vi insert mode, vi command mode,
-and emacs mode.
-The default is vi insert mode.
-The program can switch the default to emacs mode by using the
-.Xr el_set 3
-or
-.Xr el_parse 3
-functions, and the user can switch to emacs mode either in the
-.Xr editrc 5
-configuration file or interactively with the
-.Ic ed-command
-editor command, in all three cases executing the
-.Ic bind Fl e
-builtin command.
-.Pp
-If trying to read from the terminal results in end of file or an
-error, the library signals end of file to the program and does not
-return a string.
-.Ss Input character bindings
-All default bindings described below can be overridden by individual
-programs and can be changed with the
-.Xr editrc 5
-.Ic bind
-builtin command.
-.Pp
-In the following tables,
-.Sq Ctrl-
-indicates a character with the bit 0x40 flipped, and
-.Sq Meta-
-indicates a character with the bit 0x80 set.
-In vi insert mode and in emacs mode, all Meta-characters considered
-printable by the current
-.Xr locale 1
-are bound to
-.Ic ed-insert
-instead of to the editor command listed below.
-Consequently, in UTF-8 mode, most of the Meta-characters are not
-directly accessible because their code points are occupied by
-printable Unicode characters, and Meta-characters are usually input
-using the
-.Ic em-meta-next
-editor command.
-For example, to enter
-.Sq Meta-B
-in order to call the
-.Ic ed-prev-word
-editor command in emacs mode, call
-.Ic em-meta-next
-by pressing and releasing the escape key (or equivalently, Ctrl-[),
-then press and release the
-.Sq B
-key.
-If you have configured a Meta-key on your keyboard, for example
-with
-.Ql setxkbmap -option altwin:left_meta_win ,
-the Ctrl-Meta-characters are directly accessible.
-For example, to enter
-.Sq Ctrl-Meta-H
-in order to call the
-.Ic ed-delete-prev-word
-editor command in emacs mode, hold down the keys
-.Sq Ctrl ,
-.Sq Meta ,
-and
-.Sq H
-at the same time.
-Alternatively, press and release the escape key, then press and
-release
-.Sq Ctrl-H .
-.Pp
-In vi input mode, input characters are bound to the following editor
-commands by default:
-.Bl -column -offset indent "Ctrl-Z, TSTP" "ed-search-next-history"
-.It Ctrl-D, EOF Ta Ic vi-list-or-eof

-If standard output is not connected to a terminal device
-or
-.Xr el_set 3
-was used to set
-.Dv EL_EDITMODE
-to 0, all input character bindings are disabled and all characters
-typed are appended to the edit buffer.
-In that case, the edit buffer is returned to the program after a
-newline or carriage return character is typed, or after the first
-character typed if
-.Xr el_set 3
-was used to set
-.Dv EL_UNBUFFERED
-to non-zero.
-.Ss Editor commands
-Most editor commands accept an optional argument.
-The argument is entered by prefixing the editor command with one
-or more of the editor commands
-.Ic ed-argument-digit ,
-.Ic ed-digit ,
-.Ic em-universal-argument ,
-or
-.Ic vi-zero .
-When an argument is not provided, it defaults to 1.
-For most editor commands, the effect of an argument is to repeatedly
-execute the command that number of times.
-.Pp
-When talking about a character string from a left character to a
-right character, the left character is included in the string, while
-the right character is not included.
-.Pp
-If an editor command causes an error, the input character is discarded,
-no action occurs, and the terminal bell is rung.
-In case of a non-fatal error, the terminal bell is also rung,
-but the editor command takes effect anyway.

-.El
-.Ss Macros
-If an input character is bound to the editor command
-.Ic ed-sequence-lead-in ,
-.Nm
-attempts to call a macro.
-If the input character by itself forms the name of a macro, that
-macro is executed.
-Otherwise, additional input characters are read until the string
-read forms the name of a macro, in which case that macro is executed,
-or until the string read matches the beginning of none of the existing
-macro names, in which case the string including the final, mismatching
-character is discarded and the terminal bell is rung.
-.Pp
-There are two kinds of macros.
-Command macros execute a single editor command.
-Keyboard macros return a string of characters that is appended
-as a new line to the
-.Sx Input Queue .
-.Pp
-The following command macros are defined by default in vi command
-mode and in emacs mode:
-.Bl -column -offset indent "Esc O A, Esc O A" "em-exchange-mark"
-.It Esc \&[ A, Esc O A Ta Ic ed-prev-history
-.It Esc \&[ B, Esc O B Ta Ic ed-next-history
-.It Esc \&[ C, Esc O C Ta Ic ed-next-char
-.It Esc \&[ D, Esc O D Ta Ic ed-prev-char
-.It Esc \&[ F, Esc O F Ta Ic ed-move-to-end
-.It Esc \&[ H, Esc O H Ta Ic ed-move-to-beg
-.El
-.Pp
-In vi command mode, they are also defined by default without the
-initial escape character.
-.Pp
-In addition, the
-.Nm
-library tries to bind the strings generated by the arrow keys
-as reported by the
-.Xr terminfo 5
-database to these editor commands, unless that would clobber
-user settings.
-.Pp
-In emacs mode, the two-character string
-.Dq Ctrl-X Ctrl-X
-is bound to the
-.Ic em-exchange-mark
-editor command.
-.Ss Input Queue
-The
-.Nm
-library maintains an input queue operated in FIFO mode.
-Whenever it needs an input character, it takes the first character
-from the first line of the input queue.
-When the queue is empty, it reads from the terminal.
-.Pp
-A line can be appended to the end of the input queue in several ways:
-.Bl -dash -offset indent
-.It
-By calling one of the keyboard
-.Sx Macros .
-.It
-By calling the editor command
-.Ic vi-redo .
-.It
-By calling the editor command
-.Ic vi-alias .
-.It
-By pressing a key in emacs incremental search mode that doesn't
-have a special meaning in that mode but returns to normal emacs
-mode.
-.It
-If an application program directly calls the functions
-.Xr el_push 3
-or
-.Xr el_wpush 3 ,
-it can provide additional, program-specific ways
-of appending to the input queue.
