        !            56:      Boolean  options  are made TRUE by giving the name of the option as
        !            57:      an argument to the "set" command; they are made FALSE by  prefixing
        !            58:      the name  with  "no".    For  example,  "set  autoindent" makes the
        !            59:      autoindent option TRUE, and "set noautoindent" makes it FALSE.  
        !            60:

        !            71:         To change the value of a string  or  numeric  option,  pass  the
        !            72:      "set"  command  the name of the option, followed by an "=" sign and
        !            73:      the option's new value.  For example, "set tabstop=8" will give the 
        !            74:      tabstop option a value of 8.  For string options, you  may  enclose
        !            75:      the new value in quotes.

        !            80:         During  input  mode, the autoindent option will cause each added
        !            81:      line to begin with the same amount of  leading  whitespace  as  the
        !            82:      line above  it.    Without  autoindent,  added  lines are initially
        !            83:      empty.

        !            87: 
        !            88:         This option only affects EX mode.  If the autoprint  option  on,
        !            89:      and either the cursor has moved to a different line or the previous 
        !            90:      command modified the file, then Elvis will print the current line.  
        !            91:

        !            94: 
        !            95:         When  you're  editing one file and decide to switch to another -
        !            96:      via the :tag command, or :next command, perhaps - if  your  current
        !            97:      file  has  been  modified,  then Elvis will normally print an error
        !            98:      message and refuse to switch.  
        !            99: 
        !           100:         However, if the autowrite option is on, then  Elvis  will  write
        !           101:      the modified version of the current file and successfully switch to 
        !           102:      the new file.

        !           106: 
        !           107:         The :cc  command runs the C compiler.  This option should be set
        !           108:      to the name of your compiler.  
        !           109:

        !           112: 
        !           113:         Many text formatting programs allow you to designate portions of 
        !           114:      your text to be underlined, italicized, or  boldface  by  embedding
        !           115:      the special  strings  \fU,  \fI, and \fB in your text.  The special
        !           116:      string \fR marks the end of underlined or boldface text.  
        !           117: 
        !           118:         Elvis normally treats those special strings just like any  other
        !           119:      text.  
        !           120: 
        !           121:         However, if the charattr option is on, then Elvis will interpret 
        !           122:      those  special strings correctly, to display underlined or boldface
        !           123:      text on the screen.  (This only works, of course, if your  terminal
        !           124:      can  display underlined and boldface, and if the TERMCAP entry says
        !           125:      how to do it.)

        !           138: 
        !           139:         This is a "read only" option.  You can't change its  value,  but
        !           140:      you can have Elvis print it.  It shows how wide your screen is.

        !           146:      The default value is nodigraph, which means that digraphs will  not

        !           152:         Elvis stores text in temporary files.  This option allows you to 
        !           153:      control which  directory those temporary files will appear in.  The
        !           154:      default is /usr/tmp.  
        !           155: 
        !           156:         This option can only be set in a .exrc file; after  that,  elvis
        !           157:      will  have  already  started  making  temporary files in some other
        !           158:      directory, so it would be too late.

        !           162: 
        !           163:         This     option     affects     the     behaviour     of     the
        !           164:      ":s/regexp/text/options" command.    It  is normally off (:se noed)
        !           165:      which causes all of the  substitution  options  to  be  off  unless
        !           166:      explicitly given.  
        !           167: 
        !           168:         However, with edcompatible on (:se ed), the substitution command 
        !           169:      remembers which  options  you  used  last time.  Those same options
        !           170:      will continue to be used until you change them.    In  edcompatible
        !           171:      mode,  when  you explicitly give the name of a substitution option,
        !           172:      you will toggle the state of that option.  
        !           173: 
        !           174:         This all seems very strange to me, but  its  implementation  was
        !           175:      almost  free  when  I added the ":&" command to repeat the previous
        !           176:      substitution, so there it is.

        !           190: 
        !           191:         The exrefresh option is normally on, so each line is written  to

        !           277:      limit stuff  altogether.    The  big problem here is: If your arrow

        !           279:      key Elvis will wait...  and wait...  to see if maybe that  ESC  was
