Otherwise,they remain mapped to their configured bindings (normally UP_TWO lines,DOWN_TWO lines, NEXT_PAGE and PREV_PAGE respectively).<p>Note: setting emacs keys does not affect the line-editor bindings.<H1><A NAME="LL">Execution links</A></H1>If set to 'ALWAYS ON', Lynx will locally execute commands containedinside any links. This can be HIGHLY DANGEROUS, so it is recommendedthat they remain 'ALWAYS OFF' or 'FOR LOCAL FILES ONLY'.<H1><A NAME="KM">Keypad mode</A></H1>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 themwith the arrow keys. You can also number form fields.<H1><A NAME="LE">Line edit style</A></H1>This allows you to set alternate key bindings for the built-in line editor,if <A HREF="alt_edit_help.html">Alternate Bindings</A> have been installed.Otherwise, Lynx uses the <A HREF="edit_help.html">Default Binding</A>.<H1><A NAME="PM">Personal Mail Address</A></H1>You may set your mail address here so that when mailing messagesto other people or mailing files to yourself, your email address can beautomatically filled in. Your email address will also be sentto HTTP servers in a `from:' field.<H1><A NAME="PU">Pop-ups for select fields</A></H1>Lynx normally uses a pop-up window for the OPTIONs in form SELECT fieldswhen the field does not have the MULTIPLE attribute specified, and thusonly one OPTION can be selected. The use of pop-up windows can be disabledby changing this setting to OFF, in which case the OPTIONs will be renderedas a list of radio buttons. Note that if the SELECT field does havethe MULTIPLE attribute specified, the OPTIONs always are renderedas a list of checkboxes.<H1><A NAME="ST">Searching type</A></H1>If set to 'case sensitive', user searches invoked by '/' will becase-sensitive substring searches. Default is 'Case Insensitive'.<H1><A NAME="SC">Show color</A></H1>This will be present if color support is available.<ul><li>If set to ON or ALWAYS,color mode will be forced on if possible. If (n)curses color supportis available but cannot be used for the current terminal type, selecting ONis rejected with a message.<li>If set to OFF or NEVER, color mode will beturned off.<li>ALWAYS and NEVER are not offered in anonymous accounts.If saved to a '.lynxrc' file in non-anonymous accounts, ALWAYS will cause Lynxto set color mode on at startup if supported.</ul>If Lynx is built with slang,this is equivalent to having included the -color command line switchor having the COLORTERM environment variable set. If color support isprovided by curses or ncurses, this is equivalent to the default behaviorof using color when the terminal type supports it. If (n)curses color supportis available but cannot be used for the current terminal type, the preferencecan still be saved but will have no effect.<p>A saved value of NEVER willcause Lynx to assume a monochrome terminal at start-up. It is similarto the -nocolor switch, but (when the slang library is used) can be overriddenwith the -color switch. If the setting is OFF or ON when the current optionsare 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 infoindicates that you have a color-capable terminal, or (when slang is used)if forced on via the -color switch or COLORTERM variable. This defaultbehavior always is used in anonymous accounts, or if the 'option'_saverestriction is set explicitly. If for any reason the start-up color modeis incorrect for your terminal, set it appropriately on or off via this option.<H1><A NAME="CL">Show cursor for current link or option</A></H1>Lynx normally hides the cursor by positioning it to the right and if possiblethe very bottom of the screen, so that the current link or OPTION is indicatedsolely by its highlighting or color. If show cursor is set to ON, the cursorwill be positioned at the left of the current link or OPTION. This is helpfulwhen Lynx is being used with a speech or braille interface. It is also usefulfor sighted users when the terminal cannot distinguish the character attributesused to distinguish the current link or OPTION from the others in the display.<H1><A NAME="UM">User Mode</A></H1><dl><dt><EM>Novice</EM>: Shows 2 extra lines of help at the bottom of the screenfor beginners.<dt><EM>Intermediate (normal)</EM>: Normal status-line messages appear.<dt><EM>Advanced</EM>: The URL is shown on the status line.</dl><H1><A NAME="AD">Assumed document character set</A></H1>This changes the handling of documents which do not explicitly specifya charset. Normally Lynx assumes that 8-bit characters in those documentsare encoded according to iso-8859-1 (the official default for HTTP protocol).Unfortunately, many non-English web pages forget to include proper charsetinfo; this option helps you browse those broken pages if you know somehowwhat the charset is. When the value given here or by an -assume_charsetcommand-line flag is in effect, Lynx will treat documents as if they wereencoded accordingly. Option is active when 'Raw 8-bit or CJK Mode' is OFF.<H1><A NAME="JK">Raw 8-bit or CJK mode</A></H1>This is set automatically, but can be toggled manually in certain cases:it toggles whether 8-bit characters are assumed to correspond with the displaycharacter set and therefore are processed without translationvia the chartrans conversion tables. ON by default when the displaycharacter set is one of the Asian (CJK) sets and the 8-bit charactersare 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 specifiedin 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 OFFwhen an Asian (CJK) set is selected but the document is ISO-8859-1or another 'assumed document character set'. The setting can also be toggledvia the RAW_TOGGLE command, normally mapped to '@', and at startupvia the -raw switch.<H1><A NAME="tagsoup">HTML error recovery</A></H1>Lynx often has to deal with invalid HTML markup.
