OPTIONS SCREEN HELP

The Options Screen allows you to set and modify many Lynx features.
Note: some options appear on the screen only if they have been compiled in or chosen in `lynx.cfg':

Cookies

This can be set to accept or reject all cookies or to ask each time. See the Users Guide for details of cookie usage.

Editor

This is the editor to be invoked when editing browsable files, sending mail or comments, or filling form's textarea (multiline input field). The full pathname of the editor command should be specified when possible. It is assumed the text editor supports the same character set you have for "display character set" in Lynx.

Emacs keys

If set to 'ON' then the CTRL-P, CTRL-N, CTRL-F and CTRL-B keys will be mapped to up-arrow, down-arrow, right-arrow and left-arrow respectively. Otherwise, they remain mapped to their configured bindings (normally UP_TWO lines, DOWN_TWO lines, NEXT_PAGE and PREV_PAGE respectively).

Note: setting emacs keys does not affect the line-editor bindings.

Execution links

If set to 'ALWAYS ON', Lynx will locally execute commands contained inside any links. This can be HIGHLY DANGEROUS, so it is recommended that they remain 'ALWAYS OFF' or 'FOR LOCAL FILES ONLY'.

Keypad mode

This gives the choice between navigating with the keypad (as arrows; see Lynx Navigation) and having every link numbered (numbered links) so that the links may be selected by numbers instead of moving to them with the arrow keys. You can also number form fields.

Line edit style

This allows you to set alternate key bindings for the built-in line editor, if your system administrator has installed Alternate Bindings. Otherwise, Lynx uses the Default Binding.

Personal Mail Address

You may set your mail address here so that when mailing messages to other people or mailing files to yourself, your email address can be automatically filled in. Your email address will also be sent to HTTP servers in a `from:' field.

Pop-ups for select fields

Lynx normally uses a pop-up 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 pop-up 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.

Searching type

If set to 'case sensitive', user searches invoked by '/' will be case-sensitive substring searches. Default is 'Case Insensitive'.

Show color

This will be present if color support is available. If Lynx is built with slang, this is equivalent to having included the -color command line switch or having the COLORTERM 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.

A saved value of NEVER will cause Lynx to assume a monochrome terminal at start-up. It is similar to the -nocolor switch, but (when the slang library is used) can be overridden with the -color switch. If the setting is OFF or ON when the current options are saved to a '.lynxrc' file, the default start-up 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 slang is used) if forced on via the -color switch or COLORTERM variable. This default behavior always is used in anonymous accounts, or if the 'option'_save restriction is set explicitly. If for any reason the start-up color mode is incorrect for your terminal, set it appropriately on or off via this option.

Show cursor for current link or option

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 is also 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 display.

User Mode

Novice: Shows 2 extra lines of help at the bottom of the screen for beginners.
Intermediate (normal): Normal status-line messages appear.
Advanced: The URL is shown on the status line.

Assumed document character set

This changes the handling of documents which do not explicitly specify a charset. Normally Lynx assumes that 8-bit characters in those documents are encoded according to iso-8859-1 (the official default for HTTP protocol). Unfortunately, many non-English web pages forget to include proper charset info; this option helps you browse those broken pages if you know somehow what the charset is. When the value given here or by an -assume_charset command-line flag is in effect, Lynx will treat documents as if they were encoded accordingly. Option is active when 'Raw 8-bit or CJK Mode' is OFF.

Raw 8-bit or CJK mode

This is set automatically, but can be toggled manually in certain cases: it toggles whether 8-bit characters are assumed to correspond with the display character set and therefore are processed without translation via the chartrans conversion tables. ON by default when the display character set is one of the Asian (CJK) sets and the 8-bit characters are Kanji multibytes. 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 have no better idea than viewing it as from display character set (see 'assumed document character set' for best choice). 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 can also be toggled via the RAW_TOGGLE command, normally mapped to '@', and at startup via the -raw switch.

HTML error recovery

Lynx often has to deal with invalid HTML markup. It always tries to recover from errors, but there is no universally correct way for doing this. As a result, there are two parsing modes: "SortaSGML" attempts to enforce valid nesting of most tags at an earlier stage of processing, while "TagSoup" relies more on the HTML rendering stage to mimic the behavior of some other browsers. You can also switch between these modes with the CTRL-V key, and the default can be changed in lynx.cfg or with the -tagsoup command line switch.

The "SortaSGML" mode will often appear to be more strict, and makes some errors apparent that are otherwise unnoticeable. One particular difference is the handling of block elements or <li>..</li> inside <a HREF="some.url">..</a>. Invalid nesting like this may turn anchors into hidden links which cannot be easily followed, this is avoided in "TagSoup" mode. See the help on following links by number for more information on hidden links. Often pages may be more readable in "TagSoup" mode, but sometimes the opposite is true. Most documents with valid HTML, and documents with only minor errors, should be rendered the same way in both modes.

If you are curious about what goes on behind the scenes, but find that the information from the -trace switch is just too much, Lynx can be started with the -preparsed switch; going into SOURCE mode ('\' key) and toggling the parsing mode (with CTRL-V) should then show some of the differences.

Show Images

Text-based browser cannot show images directly, so we have a choice: ignore all images without ALT= text string (this is also switched by '[' key), show labels (see also "verbose images" for choice between [IMAGE] and filename), use links for every image to make it possible to download them (also switched by '*' key). Changing these settings will not be saved but could be made permanent by changing the respective settings in lynx.cfg.

Verbose Images

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 which images are decorations (button.gif, line.gif) and which are important.

VI keys

If set to 'ON' then the lowercase h, j, k and l keys will be mapped to left-arrow, down-arrow, up-arrow 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).

Note: setting vi keys does not affect the line-editor bindings.

Display Character set

This allows you to set up the default character set for your specific terminal. The display character set provides a mapping from the character encodings of viewed documents and from HTML entities into viewable characters. It should be set according to your terminal's character set so that characters other than 7-bit ASCII can be displayed correctly, using approximations if necessary, try the test here. Since Lynx now supports a wide range of platforms it may be useful to note that cpXXX codepages are used within IBM PC computers, and windows-xxxx within native MS-Windows applications.

X DISPLAY variable

This option is only relevant to X Window users. It specifies the DISPLAY (Unix) or DECW$DISPLAY (VMS) variable. It is picked up automatically from the environment if it has been previously set.

Multi-bookmarks

Manage multiple bookmark files:

Bookmark file

Manage the default bookmark file: The filepaths must be from your home directory and begin with './' if subdirectories are included (e.g., './BM/lynx_bookmarks.html').

Lynx will create bookmark files when you first 'a'dd a link, but any subdirectories in the filepath must already exist.

FTP sort criteria

This allows you to specify how files will be sorted within FTP listings. The current options include `By Filename', `By Size', `By Type', `By Date'.

List directory style

Applies to Directory Editing. Files and directories can be presented in the following ways:
Mixed style: Files and directories are listed together in alphabetical order.
Directories first: Files and directories are separated into 2 alphabetical lists: directories are listed first.
Files first: Files and directories are separated into 2 alphabetical lists: files are listed first.

Show dot files

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

Preferred Document Charset

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 make your order of preference explicit by using `q factors' as defined by the HTTP protocol, for servers which understand it: e.g., iso-8859-5, utf-8;q=0.8.

Preferred Document Language

The language you prefer if multi-language files are available from servers. Use RFC 1766 tags, e.g., `en' English, `fr' French. Can be a comma-separated list, and you can use `q factors' (see previous help item): e.g., da, en-gb;q=0.8, en;q=0.7 .

User Agent

The header string which Lynx sends to servers to indicate the User-Agent is displayed here. Changes may be disallowed via the -restrictions switch. Otherwise, the header can be changed temporarily to e.g., L_y_n_x/2.8.2 for access to sites which discriminate against Lynx based on checks for the presence of `Lynx' in the header. If changed during a Lynx session, the default User-Agent header can be restored 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 Options Menu. Changes of the header are not saved in the .lynxrc file.

NOTE Netscape Communications Corp. has claimed that false transmissions of `Mozilla' as the User-Agent are a copyright infringement, which will be prosecuted. DO NOT misrepresent Lynx as Mozilla. The Options Menu issues a warning about possible copyright infringement whenever the header is changed to one which does not include `Lynx' or `lynx'.
