NANORC(5)                              File Formats Manual                              NANORC(5)

NAME
       nanorc - GNU nano's configuration file

DESCRIPTION
       The nanorc files contain the default settings for nano, a small and friendly editor.  Dur-
       ing startup, if --rcfile is not given, nano will read two  files:  first  the  system-wide
       settings,  from  /etc/nanorc  (the exact path might be different on your system), and then
       the user-specific settings, either from ~/.nanorc or from $XDG_CONFIG_HOME/nano/nanorc  or
       from  ~/.config/nano/nanorc,  whichever  is encountered first.  If --rcfile is given, nano
       will read just the specified settings file.

NOTICE
       Since version 4.0, nano by default:

           o does not automatically hard-wrap lines that become overlong,
           o includes the line below the title bar in the editing area,
           o does linewise (smooth) scrolling.

       To get the old, Pico behavior back, you can use set breaklonglines, set emptyline, and set
       jumpyscrolling.

OPTIONS
       The  configuration  file  accepts a series of set and unset commands, which can be used to
       configure nano on startup without using command-line  options.   Additionally,  there  are
       some  commands  to  define  syntax highlighting and to rebind keys -- see the two separate
       sections on those.  nano reads one command per line.  All commands and keywords should  be
       written in lowercase.

       Options  in  nanorc  files  take precedence over nano's defaults, and command-line options
       override nanorc settings.  Also, options that do not take an argument  are  unset  by  de-
       fault.   So  using  the unset command is only needed when wanting to override a setting of
       the system's nanorc file in your own nanorc.  Options that take an argument cannot be  un-
       set.

       Quotes  inside  the  characters   parameters below should not be escaped.  The last double
       quote on the line will be seen as the closing quote.

       The supported commands and arguments are:

       set afterends
          Make Ctrl+Right and Ctrl+Delete stop at word ends instead of beginnings.

       set allow_insecure_backup
          When backing up files, allow the backup to succeed even if  its  permissions  can't  be
          (re)set due to special OS considerations.  You should NOT enable this option unless you
          are sure you need it.

       set atblanks
          When soft line wrapping is enabled, make it wrap lines at blank  characters  (tabs  and
          spaces) instead of always at the edge of the screen.

       set autoindent
          Automatically  indent  a newly created line to the same number of tabs and/or spaces as
          the previous line (or as the next line if the previous line is the beginning of a para-
          graph).

       set backup
          When saving a file, create a backup file by adding a tilde (~) to the file's name.

       set backupdir directory
          Make and keep not just one backup file, but make and keep a uniquely numbered one every
          time a file is saved -- when backups are enabled with set backup  or  --backup  or  -B.
          The uniquely numbered files are stored in the specified directory.

       set boldtext
          Use  bold  instead of reverse video for the title bar, status bar, key combos, function
          tags, line numbers, and selected text.  This can be overridden by setting  the  options
          titlecolor, statuscolor, keycolor, functioncolor, numbercolor, and selectedcolor.

       set bookstyle
          When justifying, treat any line that starts with whitespace as the beginning of a para-
          graph (unless auto-indenting is on).

       set brackets "characters"
          Set the characters treated as closing brackets when justifying  paragraphs.   This  may
          not  include  blank  characters.   Only closing punctuation (see set punct), optionally
          followed by the specified closing brackets, can end sentences.  The  default  value  is
          ""')>]}".

       set breaklonglines
          Automatically hard-wrap the current line when it becomes overlong.

       set casesensitive
          Do case-sensitive searches by default.

       set constantshow
          Constantly  display  the  cursor position in the status bar.  This overrides the option
          quickblank.

       set cutfromcursor
          Use cut-from-cursor-to-end-of-line by default, instead of cutting the whole line.

       set emptyline
          Do not use the line below the title bar, leaving it entirely blank.

       set errorcolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for the status bar when an error message is displayed.   The
          default value is bold,white,red.  See set titlecolor for valid color names.

       set fill number
          Set  the target width for justifying and automatic hard-wrapping at this number of col-
          umns.  If the value is 0 or less, wrapping will occur at the width of the screen  minus
          number  columns,  allowing the wrap point to vary along with the width of the screen if
          the screen is resized.  The default value is -8.

       set functioncolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for the concise function descriptions in the two help  lines
          at the bottom of the screen.  See set titlecolor for more details.

       set guidestripe number
          Draw  a vertical stripe at the given column, to help judge the width of the text.  (The
          color of the stripe can be changed with set stripecolor.)

       set historylog
          Save the last hundred search strings and replacement strings and executed commands,  so
          they can be easily reused in later sessions.

       set indicator
          Display  a "scrollbar" on the righthand side of the edit window.  It shows the position
          of the viewport in the buffer and how much of the buffer is covered by the viewport.

       set jumpyscrolling
          Scroll the buffer contents per half-screen instead of per line.

       set keycolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for the shortcut key combos in the two  help  lines  at  the
          bottom of the screen.  See set titlecolor for more details.

       set linenumbers
          Display  line numbers to the left of the text area.  (Any line with an anchor addition-
          ally gets a mark in the margin.)

       set locking
          Enable vim-style lock-files for when editing files.

       set magic
          When neither the file's name nor its first line give a clue, try using libmagic to  de-
          termine the applicable syntax.  (Calling libmagic can be relatively time consuming.  It
          is therefore not done by default.)

       set matchbrackets "characters"
          Specify the opening and closing brackets that can be found by bracket  searches.   This
          may  not  include  blank characters.  The opening set must come before the closing set,
          and the two sets must be in the same order.  The default value is "(<[{)>]}".

       set minibar
          Suppress the title bar and instead show information about the  current  buffer  at  the
          bottom  of the screen, in the space for the status bar.  In this "minibar" the filename
          is shown on the left, followed by an asterisk if the buffer has been modified.  On  the
          right are displayed the current line and column number, the code of the character under
          the cursor (in Unicode format: U+xxxx), the same flags as are shown by set  stateflags,
          and a percentage that expresses how far the cursor is into the file (linewise).  When a
          file is loaded or saved, and also when switching between buffers, the number  of  lines
          in  the  buffer  is displayed after the filename.  This number is cleared upon the next
          keystroke, or replaced with an [i/n] counter when multiple buffers are open.  The  line
          plus  column numbers and the character code are displayed only when set constantshow is
          used, and can be toggled on and off with M-C.  The state flags are displayed only  when
          set stateflags is used.

       set minicolor [bold,][italic,]fgcolor,bgcolor
          Use  this  color  combination for the minibar.  (When this option is not specified, the
          colors of the title bar are used.)  See set titlecolor for more details.

       set mouse
          Enable mouse support, if available for your system.  When enabled, mouse clicks can  be
          used  to  place  the cursor, set the mark (with a double click), and execute shortcuts.
          The mouse will work in the X Window System, and on the console  when  gpm  is  running.
          Text can still be selected through dragging by holding down the Shift key.

       set multibuffer
          When reading in a file with ^R, insert it into a new buffer by default.

       set noconvert
          Don't convert files from DOS/Mac format.

       set nohelp
          Don't display the two help lines at the bottom of the screen.

       set nonewlines
          Don't  automatically  add a newline when a text does not end with one.  (This can cause
          you to save non-POSIX text files.)

       set nowrap
          Deprecated option since it has become the default  setting.   When  needed,  use  unset
          breaklonglines instead.

       set numbercolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for line numbers.  See set titlecolor for more details.

       set operatingdir directory
          nano will only read and write files inside directory and its subdirectories.  Also, the
          current directory is changed to here, so files are inserted from  this  directory.   By
          default, the operating directory feature is turned off.

       set positionlog
          Save the cursor position of files between editing sessions.  The cursor position is re-
          membered for the 200 most-recently edited files.

       set preserve
          Preserve the XON and XOFF keys (^Q and ^S).

       set promptcolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for the prompt bar.  (When this option is not specified, the
          colors of the title bar are used.)  See set titlecolor for more details.

       set punct "characters"
          Set the characters treated as closing punctuation when justifying paragraphs.  This may
          not include blank characters.  Only the specfified closing punctuation, optionally fol-
          lowed  by  closing  brackets  (see  brackets), can end sentences.  The default value is
          "!.?".

       set quickblank
          Make status-bar messages disappear after 1 keystroke instead of after  20.   Note  that
          option  constantshow  overrides this.  When option minibar or zero is in effect, quick-
          blank makes a message disappear after 0.8 seconds instead of after the default 1.5 sec-
          onds.

       set quotestr "regex"
          Set  the regular expression for matching the quoting part of a line.  The default value
          is "^([ \t]*([!#%:;>|}]|//))+".  (Note that \t stands for  an  actual  Tab  character.)
          This  makes it possible to rejustify blocks of quoted text when composing email, and to
          rewrap blocks of line comments when writing source code.

       set rawsequences
          Interpret escape sequences directly, instead of asking ncurses to translate them.   (If
          you need this option to get some keys to work properly, it means that the terminfo ter-
          minal description that is used does not fully match the actual behavior of your  termi-
          nal.  This can happen when you ssh into a BSD machine, for example.)  Using this option
          disables nano's mouse support.

       set rebinddelete
          Interpret the Delete and Backspace keys differently so that both Backspace  and  Delete
          work  properly.   You  should only use this option when on your system either Backspace
          acts like Delete or Delete acts like Backspace.

       set regexp
          Do regular-expression searches by default.  Regular expressions in nano are of the  ex-
          tended type (ERE).

       set saveonexit
          Save  a changed buffer automatically on exit (^X); don't prompt.  (The old form of this
          option, set tempfile, is deprecated.)

       set scrollercolor fgcolor,bgcolor
          Use this color combination for the indicator alias "scrollbar".  (On terminal emulators
          that  link  to a libvte older than version 0.55, using a background color here does not
          work correctly.)  See set titlecolor for more details.

       set selectedcolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for selected text.  See set titlecolor for more details.

       set showcursor
          Put the cursor on the highlighted item in the file browser, and show the cursor in  the
          help viewer, to aid braille users and people with poor vision.

       set smarthome
          Make  the Home key smarter.  When Home is pressed anywhere but at the very beginning of
          non-whitespace characters on a line, the cursor will jump  to  that  beginning  (either
          forwards or backwards).  If the cursor is already at that position, it will jump to the
          true beginning of the line.

       set softwrap
          Display lines that exceed the screen's width over multiple screen lines.  (You can make
          this soft-wrapping occur at whitespace instead of rudely at the screen's edge, by using
          also set atblanks.)

       set speller "program [argument ...]"
          Use the given program to do spell checking and correcting, instead of using the  built-
          in corrector that calls hunspell(1) or spell(1).

       set spotlightcolor [bold,][italic,]fgcolor,bgcolor
          Use  this  color  combination  for  highlighting  a search match.  The default value is
          black,lightyellow.  See set titlecolor for valid color names.

       set stateflags
          Use the top-right corner of the screen for showing some state flags:  I  when  auto-in-
          denting,  M  when  the  mark  is on, L when hard-wrapping (breaking long lines), R when
          recording a macro, and S when soft-wrapping.  When the buffer is modified, a  star  (*)
          is shown after the filename in the center of the title bar.

       set statuscolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for the status bar.  See set titlecolor for more details.

       set stripecolor [bold,][italic,]fgcolor,bgcolor
          Use  this  color  combination  for the vertical guiding stripe.  See set titlecolor for
          more details.

       set suspendable
          Obsolete option; ignored.  Suspension is enabled by default, reachable via  ^T^Z.   (If
          you want a plain ^Z to suspend nano, add bind ^Z suspend main to your nanorc.)

       set tabsize number
          Use a tab size of number columns.  The value of number must be greater than 0.  The de-
          fault value is 8.

       set tabstospaces
          Convert each typed tab to spaces -- to the number of spaces that a tab at that position
          would take up.

       set titlecolor [bold,][italic,]fgcolor,bgcolor
          Use this color combination for the title bar.  Valid names for the foreground and back-
          ground colors are: red, green, blue, magenta, yellow, cyan, white, and black.  Each  of
          these eight names may be prefixed with the word light to get a brighter version of that
          color.  The word grey or gray may be used as a synonym for lightblack.  On terminal em-
          ulators  that  can  do  at least 256 colors, other valid (but unprefixable) color names
          are: pink, purple, mauve, lagoon, mint, lime, peach, orange, latte, rosy,  beet,  plum,
          sea,  sky,  slate, teal, sage, brown, ocher, sand, tawny, brick, crimson, and normal --
          where normal means the default foreground or background color.  On such emulators,  the
          color  may  also be specified as a three-digit hexadecimal number prefixed with #, with
          the digits representing the amounts of red, green, and blue, respectively.  This  tells
          nano to select from the available palette the color that approximates the given values.

          Either  "fgcolor"  or  ",bgcolor" may be left out, and the pair may be preceded by bold
          and/or italic (separated by commas) to get a bold and/or  slanting  typeface,  if  your
          terminal can do those.

       set trimblanks
          Remove  trailing  whitespace  from wrapped lines when automatic hard-wrapping occurs or
          when text is justified.

       set unix
          Save a file by default in Unix format.  This overrides nano's default behavior of  sav-
          ing a file in the format that it had.  (This option has no effect when you also use set
          noconvert.)

       set whitespace "characters"
          Set the two characters used to indicate the presence of tabs and spaces.  They must  be
          single-column  characters.  The default pair for a UTF-8 locale is ">>.", and for other
          locales ">.".

       set wordbounds
          Detect word boundaries differently by  treating  punctuation  characters  as  parts  of
          words.

       set wordchars "characters"
          Specify which other characters (besides the normal alphanumeric ones) should be consid-
          ered as parts of words.  When using this option, you probably want to unset wordbounds.

       set zap
          Let an unmodified Backspace or Delete erase the marked  region  (instead  of  a  single
          character, and without affecting the cutbuffer).

       set zero
          Hide  all elements of the interface (title bar, status bar, and help lines) and use all
          rows of the terminal for showing the contents of the buffer.  The  status  bar  appears
          only  when there is a significant message, and disappears after 1.5 seconds or upon the
          next keystroke.  With M-Z the title bar plus status bar can be toggled.  With  M-X  the
          help lines.

SYNTAX HIGHLIGHTING
       Coloring  the  different syntactic elements of a file is done via regular expressions (see
       the color command below).  This is inherently imperfect, because regular  expressions  are
       not powerful enough to fully parse a file.  Nevertheless, regular expressions can do a lot
       and are easy to make, so they are a good fit for a small editor like nano.

       All regular expressions in nano are POSIX extended regular expressions.  This  means  that
       ., ?, *, +, ^, $, and several other characters are special.  The period . matches any sin-
       gle character, ? means the preceding item is optional, * means the preceding item  may  be
       matched  zero or more times, + means the preceding item must be matched one or more times,
       ^ matches the beginning of a line, and $ the end, \< matches the start of a word,  and  \>
       the end, and \s matches a blank.  It also means that lookahead and lookbehind are not pos-
       sible.  A complete explanation can be found in the manual page of GNU grep: man grep.

       For each kind of file a separate syntax can be defined via the following commands:

       syntax name ["fileregex" ...]
              Start the definition of a syntax with this name.  All subsequent  color  and  other
              such  commands  will be added to this syntax, until a new syntax command is encoun-
              tered.

              When nano is run, this syntax will be automatically activated if the current  file-
              name  matches  the extended regular expression fileregex.  Or the syntax can be ex-
              plicitly activated by using the -Y or --syntax command-line option followed by  the
              name.

              The  syntax  default  is  special: it takes no fileregex, and applies to files that
              don't match any syntax's regexes.  The syntax none is reserved;  specifying  it  on
              the command line is the same as not having a syntax at all.

       header "regex" ...
              If  from  all  defined  syntaxes  no fileregex matched, then compare this regex (or
              regexes) against the first line of the current file, to determine whether this syn-
              tax should be used for it.

       magic "regex" ...
              If no fileregex matched and no header regex matched either, then compare this regex
              (or regexes) against the result of querying the magic database  about  the  current
              file,  to determine whether this syntax should be used for it.  (This functionality
              only works when libmagic is installed on the system and will  be  silently  ignored
              otherwise.)

       formatter program [argument ...]
              Run  the  given  program  on the full contents of the current buffer.  (The current
              buffer is written out to a temporary file, the program is run on it, and  then  the
              temporary file is read back in, replacing the contents of the buffer.)

       linter program [argument ...]
              Use the given program to run a syntax check on the current buffer.

       comment "string"
              Use the given string for commenting and uncommenting lines.  If the string contains
              a vertical bar or pipe character (|), this designates bracket-style  comments;  for
              example,  "/*|*/"  for  CSS files.  The characters before the pipe are prepended to
              the line and the characters after the pipe are appended at the end of the line.  If
              no  pipe  character  is present, the full string is prepended; for example, "#" for
              Python files.  If empty double quotes are specified, the comment/uncomment function
              is disabled; for example, "" for JSON.  The default value is "#".

       tabgives "string"
              Make the <Tab> key produce the given string.  Useful for languages like Python that
              want to see only spaces for indentation.  This overrides the setting  of  the  tab-
              stospaces option.

       color [bold,][italic,]fgcolor,bgcolor "regex" ...
              Paint  all pieces of text that match the extended regular expression regex with the
              given foreground and background colors, at least one of which  must  be  specified.
              Valid  color  names are: red, green, blue, magenta, yellow, cyan, white, and black.
              Each of these eight names may be prefixed with the word light  to  get  a  brighter
              version  of  that color.  The word grey or gray may be used as a synonym for light-
              black.  On terminal emulators that can do at least 256 colors, other valid (but un-
              prefixable)  color  names  are: pink, purple, mauve, lagoon, mint, lime, peach, or-
              ange, latte, rosy, beet, plum, sea, sky, slate, teal,  sage,  brown,  ocher,  sand,
              tawny,  brick,  crimson, and normal -- where normal means the default foreground or
              background color.  On such emulators, the color may also be specified as  a  three-
              digit  hexadecimal number prefixed with #, with the digits representing the amounts
              of red, green, and blue, respectively.  This tells nano to select from  the  avail-
              able palette the color that approximates the given values.

              The color pair may be preceded by bold and/or italic (separated by commas) to get a
              bold and/or slanting typeface, if your terminal can do those.

              All coloring commands are applied in the order in which they are  specified,  which
              means that later commands can recolor stuff that was colored earlier.

       icolor [bold,][italic,]fgcolor,bgcolor "regex" ...
              Same as above, except that the matching is case insensitive.

       color [bold,][italic,]fgcolor,bgcolor start="fromrx" end="torx"
              Paint all pieces of text whose start matches extended regular expression fromrx and
              whose end matches extended regular expression torx with the  given  foreground  and
              background colors, at least one of which must be specified.  This means that, after
              an initial instance of fromrx, all text until the first instance of  torx  will  be
              colored.  This allows syntax highlighting to span multiple lines.

       icolor [bold,][italic,]fgcolor,bgcolor start="fromrx" end="torx"
              Same as above, except that the matching is case insensitive.

       include "syntaxfile"
              Read  in  self-contained  color syntaxes from syntaxfile.  Note that syntaxfile may
              contain only the above commands, from syntax to icolor.

       extendsyntax name command argument ...
              Extend the syntax previously defined as name with  another  command.   This  allows
              adding  a new color, icolor, header, magic, formatter, linter, comment, or tabgives
              command to an already defined syntax -- useful when you want to slightly improve  a
              syntax  defined  in  one  of  the  system-installed  files  (which normally are not
              writable).

REBINDING KEYS
       Key bindings can be changed via the following three commands:

          bind key function menu
                 Rebinds the given key to the given function in the given menu (or in  all  menus
                 where the function exists when all is used).

          bind key "string" menu
                 Makes  the given key produce the given string in the given menu (or in all menus
                 where the key exists when all is used).  The string can consist of text or  com-
                 mands  or  a mix of them.  (To enter a command into the string, precede its key-
                 stroke with M-V.)

          unbind key menu
                 Unbinds the given key from the given menu (or from all menus where the  key  ex-
                 ists when all is used).

       The format of key should be one of:

          ^X     where  X  is a Latin letter, or one of several ASCII characters (@, ], \, ^, _),
                 or the word "Space".  Example: ^C.

          M-X    where X is any ASCII character except [, or the word "Space".  Example: M-8.

          Sh-M-X where X is a Latin letter.  Example: Sh-M-U.  By default, each Meta+letter  key-
                 stroke  does  the  same  as  the  corresponding Shift+Meta+letter.  But when any
                 Shift+Meta bind is made, that will no longer be the case, for all letters.

          FN     where N is a numeric value from 1 to 24.  Example: F10.  (Often, F13 to F24  can
                 be typed as F1 to F12 with Shift.)

          Ins or Del.

       Rebinding  ^M  (Enter) or ^I (Tab) is probably not a good idea.  Rebinding ^[ (Esc) is not
       possible, because its keycode is the starter byte of Meta keystrokes and escape sequences.
       Rebinding any of the dedicated cursor-moving keys (the arrows, Home, End, PageUp and Page-
       Down) is not possible.  On some terminals it's not possible to rebind ^H (unless --raw  is
       used) because its keycode is identical to that of the Backspace key.

       Valid function names to be bound are:

          help
            Invokes the help viewer.

          cancel
            Cancels the current command.

          exit
            Exits from the program (or from the help viewer or file browser).

          writeout
            Writes the current buffer to disk, asking for a name.

          savefile
            Writes the current file to disk without prompting.

          insert
            Inserts  a  file  into the current buffer (at the current cursor position), or into a
            new buffer when option multibuffer is set.

          whereis
            Starts a forward search for text in the current buffer -- or for filenames matching a
            string in the current list in the file browser.

          wherewas
            Starts  a backward search for text in the current buffer -- or for filenames matching
            a string in the current list in the file browser.

          findprevious
            Searches the next occurrence in the backward direction.

          findnext
            Searches the next occurrence in the forward direction.

          replace
            Interactively replaces text within the current buffer.

          cut
            Cuts and stores the current line (or the marked region).

          copy
            Copies the current line (or the marked region) without deleting it.

          paste
            Pastes the currently stored text into the current buffer at the current cursor  posi-
            tion.

          zap
            Throws  away the current line (or the marked region).  (This function is bound by de-
            fault to <Meta+Delete>.)

          chopwordleft
            Deletes from the cursor position to the beginning of the preceding word.  (This func-
            tion  is  bound  by default to <Shift+Ctrl+Delete>.  If your terminal produces ^H for
            <Ctrl+Backspace>, you can make <Ctrl+Backspace> delete the word to the  left  of  the
            cursor by rebinding ^H to this function.)

          chopwordright
            Deletes  from  the cursor position to the beginning of the next word.  (This function
            is bound by default to <Ctrl+Delete>.)

          cutrestoffile
            Cuts all text from the cursor position till the end of the buffer.

          mark
            Sets the mark at the current position, to start selecting text.  Or, when it is  set,
            unsets the mark.

          location
            Reports the current position of the cursor in the buffer: the line, column, and char-
            acter positions.  (The old name of this function, 'curpos', is deprecated.)

          wordcount
            Counts and reports on the status bar the number of lines, words,  and  characters  in
            the current buffer (or in the marked region).

          execute
            Prompts  for  a  program  to execute.  The program's output will be inserted into the
            current buffer (or into a new buffer when M-F is toggled).

          speller
            Invokes a spell-checking program, either the default hunspell(1) or GNU spell(1),  or
            the one defined by --speller or set speller.

          formatter
            Invokes a full-buffer-processing program (if the active syntax defines one).

          linter
            Invokes a syntax-checking program (if the active syntax defines one).

          justify
            Justifies  the  current  paragraph (or the marked region).  A paragraph is a group of
            contiguous lines that, apart from possibly the first line, all have the same indenta-
            tion.   The beginning of a paragraph is detected by either this lone line with a dif-
            fering indentation or by a preceding blank line.

          fulljustify
            Justifies the entire current buffer (or the marked region).

          indent
            Indents (shifts to the right) the current line or the marked lines.

          unindent
            Unindents (shifts to the left) the current line or the marked lines.

          comment
            Comments or uncomments the current line or the marked lines, using the comment  style
            specified in the active syntax.

          complete
            Completes  (when  possible) the fragment before the cursor to a full word found else-
            where in the current buffer.

          left
            Goes left one position (in the editor or browser).

          right
            Goes right one position (in the editor or browser).

          up
            Goes one line up (in the editor or browser).

          down
            Goes one line down (in the editor or browser).

          scrollup
            Scrolls the viewport up one row (meaning that the text slides down) while keeping the
            cursor in the same text position, if possible.  (This function is bound by default to
            <Alt+Up>.   If  <Alt+Up>  does  nothing  on  your  Linux  console,   see   the   FAQ:
            <https://nano-editor.org/dist/latest/faq.html#4.1>.)

          scrolldown
            Scrolls the viewport down one row (meaning that the text slides up) while keeping the
            cursor in the same text position, if possible.  (This function is bound by default to
            <Alt+Down>.)

          center
            Scrolls the line with the cursor to the middle of the screen.

          prevword
            Moves the cursor to the beginning of the previous word.

          nextword
            Moves the cursor to the beginning of the next word.

            Moves the cursor to the end of the current paragraph.

          prevblock
            Moves the cursor to the beginning of the current or preceding block of text.  (Blocks
            are separated by one or more blank lines.)

          nextblock
            Moves the cursor to the beginning of the next block of text.

          pageup
            Goes up one screenful.

            Goes to the last line of the file.

          gotoline
            Goes to a specific line (and column if specified).  Negative numbers count  from  the
            end of the file (and end of the line).

          findbracket
            Moves  the cursor to the bracket (or brace or parenthesis, etc.) that matches (pairs)
            with the one under the cursor.  See set matchbrackets.

          anchor
            Places an anchor at the current line, or removes it when already present.  (An anchor
            is visible when line numbers are activated.)

          prevanchor
            Goes to the first anchor before the current line.

          nextanchor
            Goes to the first anchor after the current line.

          delete
            Deletes the character under the cursor.

          backspace
            Deletes the character before the cursor.

          recordmacro
            Starts the recording of keystrokes -- the keystrokes are stored as a macro.  When al-
            ready recording, the recording is stopped.

          runmacro
            Replays the keystrokes of the last recorded macro.

          undo
            Undoes the last performed text action (add text, delete text, etc).

          redo
            Redoes the last undone action (i.e., it undoes an undo).

          refresh
            Refreshes the screen.

          suspend
            Suspends the editor and returns control to the shell (until you tell the  process  to
            resume execution with fg).

          casesens

            format.  Converting is the default.

          dosformat
            When writing a file, switches to writing a DOS format (CR/LF).

          macformat
            When writing a file, switches to writing a Mac format.

          append

          prepend
            When writing a file, 'prepends' (writes at the beginning) instead of overwriting.

          backup
            When writing a file, creates a backup of the current file.

          discardbuffer
            When about to write a file, discard the current buffer without saving.   (This  func-
            tion is bound by default only when option --saveonexit is in effect.)

          browser
            Starts  the file browser (in the Read File and Write Out menus), allowing to select a
            file from a list.

          gotodir
            Goes to a directory to be specified, allowing to browse anywhere in the filesystem.

            Toggles the presence of the two-line list of  key  bindings  at  the  bottom  of  the
            screen.  (This toggle is special: it is available in all menus except the help viewer
            and the linter.  All further toggles are available in the main menu only.)

          autoindent
            Toggles whether a newly created line will contain the same amount of  leading  white-
            space  as  the preceding line -- or as the next line if the preceding line is the be-
            ginning of a paragraph.

          cutfromcursor

            position to the end of the line.

          breaklonglines
            Toggles  whether  long lines will be hard-wrapped to the next line.  (The old name of
            this function, 'nowrap', is deprecated.)
