   <dt>Multi-bookmarks
        <dd>Lynx supports a default bookmark file, and up to 26 total
            bookmark files (see below).  When multi-bookmarks is OFF,
            the default bookmark file is used for the '<em>v</em>'iew
            bookmarks and '<em>a</em>'dd bookmark link commands.  If
            multi-bookmark support is available in your account, the
            setting can be changed to STANDARD or ADVANCED.  In STANDARD
            mode, a menu of available bookmarks always is invoked when
            you seek to view a bookmark file or add a link, and you select
            the bookmark file by its letter token (see
            <em>Bookmark file</em>, below) in that menu.  In ADVANCED mode,
            you instead are prompted for the letter of the desired bookmark
            file, but can enter '<em>=</em>' to invoke the STANDARD selection
            menu, or <em>RETURN</em> for the default bookmark file.

   <dt>Personal mail address
        <dd>This mail address will be used to help you send files to
            yourself and will be included as the From: address in any mail
            or comments that you send.  It will also be sent as the From:
            field in HTTP or HTTPS requests if inclusion of that header
            has been enabled via the NO_FROM_HEADER definition in
            <A HREF="#lynx.cfg">lynx.cfg</A>
            (the compilation default is not to send the header), or via the
            <em>-from</em> command line toggle.

   <dt>Popups for select fields
        <dd>Lynx normally uses a popup window for the OPTIONs in form
            SELECT fields when the field does not have the MULTIPLE
            attribute specified, and thus only one OPTION can be selected.
            The use of popup windows can be disabled by changing this setting
            to OFF, in which case the OPTIONs will be rendered as a list of
            radio buttons.  Note that if the SELECT field does have the
            MULTIPLE attribute specified, the OPTIONs always are rendered
            as a list of checkboxes.

   <dt>Preferred Document Language
        <dd>The language you prefer if multi-language files are available
            from servers.  Use RFC 1766 abbreviations, e.g., en for English,
            fr for French, etc.  Can be a comma-separated list, which may
            be interpreted by servers as descending order of preferences.
            You can also make your order of preference explicit by using
            q factors as defined by the HTTP protocol, for servers which
            understand it, for example:
            da,&nbsp;en-gb;q=0.8,&nbsp;en;q=0.7

   <dt>Preferred Document Charset
        <dd>The character set you prefer if sets in addition to ISO-8859-1
            and US-ASCII are available from servers.  Use MIME notation
            (e.g., ISO-8859-2) and do not include ISO-8859-1 or US-ASCII,
            since those values are always assumed by default.  Can be a
            comma-separated list, which may be interpreted by servers as
            descending order of preferences.  You can also make your order
            of preference explicit by using q factors as defined by the
            HTTP protocol, for servers which understand it, for example:
            iso-8859-5,&nbsp;utf-8;q=0.8

   <dt>Raw 8-bit or CJK Mode
        <dd>Whether 8-bit characters are assumed to correspond with the
            display character set and therefore are processed without
            translation via the chartrans conversion tables.  Should be ON
            by default when the display character set is one of the
            Asian (CJK) sets and the 8-bit characters are Kanji multibytes.
            Should be OFF for the other display character sets,
            but can be turned ON
            when the document's charset is unknown (e.g., is not ISO-8859-1
            and no charset parameter was specified in a reply header from
            an HTTP server to indicate what it is) but you know by some
            means that you have the matching display character set selected.
            Should be OFF when an Asian (CJK) set is selected but the document
            is ISO-8859-1 or another 'assumed document character set'.
            The setting also can be toggled via the RAW_TOGGLE
            command, normally mapped to '<em>@</em>', and at startup via the
            <em>-raw</em> switch.

   <dt>Show color.
        <dd>This option will be present if color support is available.
            If set to ON or ALWAYS, color mode will be forced on if possible.
            If (n)curses color support is available but cannot be used for
            the current terminal type, selecting ON is rejected with a message.
            If set to OFF or NEVER, color mode will be turned off.<BR>
            ALWAYS and
            NEVER are not offered in anonymous accounts.  If saved to a
            <em>.lynxrc</em> file in non-anonymous accounts, ALWAYS will
            cause Lynx to set color mode on at startup if supported.
            If Lynx is built with the slang library, this is equivalent to
            having included the <em>-color</em> command line switch or having the
            <em>COLORTERM</em> environment variable set.  If color support is
            provided by curses or ncurses, this is equivalent to the default
            behavior of using color when the terminal type supports it.
            If (n)curses color support is available but cannot be used for
            the current terminal type, the preference can still be saved
            but will have no effect.<BR>
            A saved value of NEVER will
            cause Lynx to assume a monochrome terminal at startup.
            It is similar to the <em>-nocolor</em> switch, but (when the
            slang library is used) can be overridden with the <em>-color</em>
            switch.<BR>
            If the setting is OFF or ON
            when the current options are saved to a <em>.lynxrc</em> file,
            the default startup behavior is retained, such that color mode
            will be turned on at startup only if the terminal info indicates
            that you have a color-capable terminal, or (when the
            slang library is used) if forced on via the
            <em>-color</em> switch or <em>COLORTERM</em> variable.  This
            default behavior always is used in anonymous accounts, or if
            the <em>option_save</em> restriction is set explicitly.  If
            for any reason the startup color mode is incorrect for your
            terminal, set it appropriately on or off via this option.

   <dt>Searching type
        <dd>Searching type has two possible values: CASE INSENSITIVE
            (default) and CASE SENSITIVE.  The searching type effects
            inter-document searches only, and determines whether searches
            for words within documents will be done in a case-sensitive or
            case-insensitive manner.

   <dt>Show cursor for current link or option.
        <dd>Lynx normally hides the cursor by positioning it to the right
            and if possible the very bottom of the screen, so that the
            current link or OPTION is indicated solely by its highlighting
            or color.  If show cursor is set to ON, the cursor will be
            positioned at the left of the current link or OPTION.  This
            is helpful when Lynx is being used with a speech or braille
            interface.  It also is useful for sighted users when the
            terminal cannot distinguish the character attributes used
            to distinguish the current link or OPTION from the others in
            the screen display.

   <dt>Show dot files
        <dd>If display/creation of hidden (dot) files/directories is
            enabled, you can turn the feature on or off via this setting.

   <dt>Use locale-based character set
        <dd>This option allows you to request lynx to obtain a MIME name
            from the operating system which corresponds to your locale
            setting.  If successful, it overrides the normal setting of
            the display character set.

   <dt>Underline links
        <dd>Use underline-attribute rather than bold for links.

   <dt>User Agent
        <dd>The header string which Lynx sends to HTTP servers to indicate the
            User-Agent is displayed here.  Changes may be disallowed via
            the <em>-restrictions</em> switch.  Otherwise, the header can be
            changed temporarily to a string such as <em>L_y_n_x/2.8.5</em>
            for access to sites which discriminate against Lynx based on
            checks for the presence of &quot;Lynx&quot; in the header.  If
            the User-Agent header has been changed, it can
            be restored to the built-in default value
            by deleting the modified string in the
            Options Menu.  Whenever the User-Agent header is
            changed, the current document is reloaded, with the no-cache
            flags set, on exit from the Options Menu.   Changes of
            the header are not saved in the RC file.
        <dd><em ID="noteUA">NOTE:</em> Some sites may regard misrepresenting
            the browser
            as fraudulent deception, or as gaining unauthorized access, if
            it is used to circumvent blocking that was intentionally put in
            place.  Some browser manufacturers may find the transmission of
            their product's name objectionable.  If you change the User-Agent
            string, it is your responsibility.  The Options Menu issues
            a reminder whenever the
            header is changed to one which does not include &quot;Lynx&quot;
            or &quot;L_y_n_x&quot;.

   <dt>User Mode
       <dd>There are three possible choices: Novice, Intermediate, and
           Advanced.
         <dl>
            <dt>Novice
                <dd>In Novice mode two lines of help are displayed at the
                    bottom of the screen.
            <dt>Intermediate
                <dd>Intermediate mode turns off the help lines.
            <dt>Advanced
                <dd>Advanced mode displays the URL of the currently selected
                    link at the bottom of the screen.
         </dl>

   <dt>Verbose Images
        <dd>Controls whether or not Lynx replaces the [LINK], [INLINE] and
            [IMAGE] comments (for images without ALT) with filenames of these
            images.  This is extremely useful because now we can determine
            immediately what images are just decorations (button.gif, line.gif)
            and what images are important.  This setting can also be toggled
            on startup via the <em>-verbose</em> switch.

   <dt>VI keys
        <dd>If set to ON then the lowercase h, j, k, and l keys will be
            mapped to left, down, up, and right arrow, respectively.  The
            uppercase H, J, K, and L keys remain mapped to their configured
            bindings (normally HELP, JUMP, KEYMAP, and LIST, respectively).

         <p>Note: this has no effect on the line-editor's key bindings.

   <dt>Visited Pages
        <dd>Enable several different views of the visited links:
        <dl>
          <dt>By First Visit
          <dt>By First Visit Reversed
          <dt>As Visit Tree
          <dt>By Last Visit
          <dt>By Last Visit Reversed
        </dl>
</dl>

<h2 ID="Mail"><A NAME="Mail"><em>Comments and mailto: links</em></A></h2>

At any time while viewing documents within Lynx, you may use the
'<em>c</em>' command to send a mail message to the owner of the current
document if the author of the document has specified ownership.  (Note to
authors: if you want to assign the ownership to your document, you need to add
into HEAD section a LINK element with appropriate value for REV attribute.  Two
values are recognized: <em>owner</em> and <em>made</em> (these are case
insensitive).  For example, <pre>
&lt;HEAD&gt;
    &#8230;
    &lt;LINK REV="made" HREF="mailto:[e-mail]"&gt;
    &#8230;
&lt;HEAD&gt;
</pre>
You may also add a TITLE attribute with, for example, the name of your page) If
no ownership is specified then comments are disabled.  Certain links called
<a href="lynx_url_support.html#mailto">mailto:</a> links will also allow
you to send mail to other people.  Using the mail features within Lynx is
straightforward.

<p>Once you have decided to send a comment or have selected a
<em>mailto:</em> link a new screen will appear showing you to whom you
are sending the message.  Lynx will ask for your name, your e-mail
address, and the subject of the message.  If you have filled in the
"personal mail address" field in the <em>Options Menu</em>, your e-mail
address will be filled in automatically.  After entering the above
information, if you have an editor defined in the <em>Options Menu</em>
and you are not an anonymous user then your specified editor will be
spawned for you so  that you can enter your message.  If you do not have
an editor defined or you are an anonymous user, a simple line mode input
scheme will allow you to enter your message.

<p>To finish sending the message, exit your spawned editor or, if you are
using the simple line mode input scheme, type a '<em>.</em>' (period) on
a line by itself.  You will be asked a final time whether to send the
message.  If you press '<em>y</em>', you will be prompted whether to
append your signature file if one was defined in
<A HREF="#lynx.cfg">lynx.cfg</A> and is accessible,
and then the message will be sent, whereas if you press '<em>n</em>' the
message will be deleted.  Entering Control-G in response to any prompts
also will cancel the mailing.[<A HREF="#ToC-Mail">ToC</A>]
